Part 1

With a short sword in hand, Kousuke stood between Emily and Down.

Kousuke was staring at Emily right from the front.

Yes, Kousuke split apart the fired bullet in midair, was to protect Down behind him. What he cut was Emily’s bullet.

「Ko, Kousuke……why-」

Emily questioned with the gun still raised in her trembling hand.

Kousuke slowly walked forward without any words, he didn’t even glance at Down behind him. And then, when he arrived until in front of Emily who was shaking her head left and right, he put his hand softly on the gun barrel and gently lowered it down.

「Stop it, Emily. This is not your role.」

A calm voice and a composed gaze enveloped Emily.

But, Kousuke felt a slight resistance at his hand that was put on the gun barrel. Emily was rejecting it. He could see a tragic resolve inside the eyes of Emily who was shaking her head left and right.

Kousuke didn’t know. About the words exchanged between Emily and Down.

Even so he was able to guess. Just with what kind of feeling Emily pulled the trigger. Just with what kind of feeling, she directed a killing intent at the man who she thought as a teacher and also a substitute of father.

Surely she felt hatred. Surely she also felt resentment. But, her act didn’t come only from being captured by those kinds of negative emotions and ended in madness.

Inside her eyes there was a sense of purpose. Or possibly a sense of duty. And then a sense of responsibility.

Kousuke smiled wryly in his heart, thinking that it was like Emily. Even so his hand didn’t let go from Emily’s gun that refused to be lowered.

「Kousuke-, this is something that I started, that’s why-. That’s why-」

「Is that really so? I don’t think so though. Well, even so if that’s what Emily yourself think, then I won’t really deny it. However, the end of this path is no good. It’s not a destination where Emily should go.」

He wouldn’t let her go through the path of murder. Kousuke responded with a feeling that was equally strong with the feeling Emily held.

Even so, Emily was about to object further, but Kousuke added his words.

「Because, that’s something that run counter to the wish of Emily’s big brothers and sisters right?」

「-」

Yes, no one was demanding this kind of conclusion from Emily. Even though Kousuke had never met them, even though he had never exchanged words with them, but just from hearing Emily’s story, it was something obvious to Kousuke.

There was no way they who risked their life to protect their important little sister would wish for this.

「Emily’s dream, is to save those who are suffering sickness right?」

She wished to heal her grandmother. Emily’s step that was starting from such wish, surely it was them who were rooting for it more than anyone.

「They should believe, more than anyone. Emily’s hand, it isn’t something to hurt others. It’s something to heal, to save others.」

That was why, not a single one of them blamed Emily for creating the drug of madness. They didn’t escape by saying that it was unrelated with them. They understood that it was an outrageous situation, yet they didn’t leave Emily’s side by any means.

That was why,

「My bad, but I’m not going to allow this yeah? I absolutely won’t allow only this. No matter how strong Emily’s will is, I’ll stop you with my all. Endo Kousuke, the right-hand man of the demon king and also your protector, this me will stop you with my whole body and soul. Emily Grant has reached this far by doing her best to save others. Something like the closing of curtain by such a girl murdering someone who was family, I won’t let that happen.」

「Kou, suke……」

Strength left Emily’s hand. *gatan* A sound rang. The handgun that slipped unhindered from Emily’s hand, it fell on the floor.

Surely there wasn’t any way to express the overflowing emotion inside her. All the words that existed in this world were too inadequate for that. She wondered, just how many times this body, this heart had been protected. When she needed it, a help would be given to her then without fail, by Emily Grant’s hero.

Softly, Emily’s head leaned on Kousuke’s chest. *drop, drop* The falling tears on the floor were surely the result of her emotion that couldn’t be worded appearing in a definite shape.

Kousuke gently put his hand on the head of Emily who was burying her face on his chest while trembling. He exchanged gaze with Vanessa who was relieved while still lying down on the floor and they nodded at each other.

「……So even that berserker cannot stop you. I’m keenly feeling the irrationality of your existence thoroughly.」

Down said that with an astonished expression. He wasn’t running away or shooting while Kousuke and Emily were talking. Kousuke turned a suspicious gaze at Down who was like that.

「You aren’t running away?」

「Will you let me run away?」

Down replied so while smiling bitterly. There wasn’t any hostility, or fluster and desperation that were particular for a cornered person that could be seen from him. Kousuke’s gaze narrowed in wonder of what this person was thinking. And what bothered him above all, was the reason why Down didn’t shoot.

At that time, Kousuke only cut Emily’s bullet. He used gravity magic to suck in the bullet toward his blade and slashed the bullet that shifted slightly. Naturally, he planned to use his kunai to repel the bullet that he thought would approach from behind him but……

In the first place, Down didn’t pull his trigger at that time. Down had no intention of killing Emily.

「Just what in the world you are planning?」

「Of course, I’m thinking about myself. I have been thinking only about myself since I stole Berserk.」

Kousuke thought that perhaps, by any chance Down actually hesitated to shoot because of his affection toward Emily, but it seemed that wasn’t it. Down’s calm and composed gaze and voice seemed even more eerie.

「……I don’t know what you are thinking, but for now, surrender.」

「Oho, you won’t kill me?」

「I just don’t want Emily to lose more person close to her. ……Even if that person is only “formerly” close to her, or even if that person is an unforgivable traitor.」

If Kousuke had to say more, he also had the calculation of wanting to hand over the case’s ringleader to Chief Magdanese. Kousuke thought that it would be also necessary for Emily’s life from here on that there was the result of “the culprit was captured” regarding the【Berserk Case】that shaken the world.

Kousuke’s words caused Emily to raise her face from his chest and she looked at Down. Her gaze was certainly wishing not for Down’s death, but for him to be judged by the administration of justice.

Down listened at Kousuke’s words, and then he saw Emily’s gaze before he sighed deeply.

「Haa, really, nothing has gone well at all. Perhaps this is also because I’m mediocre.」

Saying that, Down took one, two steps back. Kousuke leaped out without any question. He would hold him down and then robbed him of his consciousness. With the danger of Berserk, it was a great concern even to just speak at him.

When Kousuke stepped at the second floor’s passage, it was at the same time when Down fell into the water reservoir from his back. Emily reflexively yelled「Teacher-」.

Kousuke jumped in to overtake Down and caught him midair. But, when he tried to hover midair, his body lurched forward with a jerk. Kousuke launched a steel string from his sleeve in panic to seize the handrail of the passage and he dangled down.

Kousuke’s movement was lacking in luster. Originally he should be able to make Down unconscious before he could jump down, but he was unable to do that was because of the effect of the previous battle.

The rapid Limit Break by using Last Zell. Naturally, he was unable to escape from the side effect. Currently Kousuke was in the middle of a remarkable weakening. He was unable to create clone, and his physical ability decreased by sixty percent. He was being assaulted by fatigue that made him wanted to just fall asleep right now. Honestly, he already felt his consciousness getting farther when he used gravity magic to suck in the bullet.

「You plan to suicide huh!」

「That’s right. Though actually I wanted Emily to kill me. After all, I understand that I won’t be able to escape. If that’s not the case, do you think I will talk that long even understanding that a monster like you is here?」

Down spoke about his own end really easily while dangling in midair seized by Kousuke.

「Although, as expected I didn’t think that berserker will be defeated this quickly though.」

「Teacher-, what are you doing!? Didn’t you want to leave your name in history!?」

Emily’s words caused Down to answer with a mysterious expression that was a mixture of resignation and madness.

「That’s right. I’ll leave my name in history. If I cannot escape anymore, then I’ll leave my name as the tragic father who tried to stop the girl that scattered disaster in this world!」

With those words, Kousuke finally guessed the thinking of what Down was trying to do. And then, he said「This stupid bastard-」while trying to throw Down on the floor.

But, before he could,

「If even that cannot come true then! Aa, fine then. I will become that very disaster itself! I’ll leave my name in history not with a great achievement, but with a great sin!」

Saying that, he exploded the moment Kousuke threw him.

*doon-* The moment that muffled sound rang, Down’s stomach exploded. Naturally, his blood and flesh scattered.  Emily became unable to move due to the abnormal situation that was too gruesome.

Kousuke desperately maintained his creaking body and his distant consciousness. He activated gravity magic while leaping toward Emily right away.

Even gravity magic that was unable to completely display its effect was able to at least knock off the approaching blood and flesh.

But, for the current Kousuke that was his limit. Down that changed his route using the impact fell into the water reservoir along with his scattered blood and flesh.

A grand spray of water rose, creating a fierce ripple at the water reservoir. At the same time, the clear and transparent water was dyed red as though ink was spilled into it.

「……」

「Damn it-, he got us-」

Emily was dumbfounded without any words while staring at the water reservoir that was dyed red while Kousuke laid bare his irritation.

「Kousuke-san-, this is!」

The lying down Vanessa threw a radio at Kousuke. Kousuke guessed what she meant and received the radio before speaking into it.

『Bernard! Can you hear me!?』

『Mu, Aby. What’s the matter?』

『Berserk spilled into the waterway! The water gate is opened and it’s flowing to somewhere! Anywhere is fine, just stop the flow before it can go through the water supply facility!』

『-. Wait a second! ――Control room-. Seal all the waterways!』

Bernard who received the contact gave instruction to his subordinates that suppressed the control room.

Just as Kousuke said, Down didn’t just blow himself up. “Scattering disaster”――just as those words meant, he wasn’t trying to transform himself into a berserker, but he exploded himself to scatter the Berserk that was stored inside his stomach and spilled it into the waterway.

Most likely this aberrant plan was hatched because of the irregularity that was Kousuke. This was Down’s final attack from thinking of the possibility that anything he did would be prevented.

No matter what place it was, no matter what reason it was for, a person who staked their life on the line was terrifying. Kousuke who got outwitted painfully realized that once more while he gritted his teeth.

Then, it was at that time a voice that sounded like a shriek rang from the radio.

『Captain-, the control doesn’t work! Both the clean water facility or the water supply facility, all of them won’t move from the opened gate state! The control is completely on the fritz!』

『What did you say-. What’s the meaning of this!?』

『Those guys, perhaps they are inserting virus to the computer-. If I have time then I think it’s possible to recover the control though.』

『How long that will take?』

『……Ten minutes. No, if I have just eight minutes, I’ll somehow……』

『Tsk, get on it right away.』

『Yes Sir-』

Silence ruled over the place for a while. At this rate, the irrigation that was polluted by Berserk would flow into a city. Even before that, it would pass through several towns. If that happened, the wave of berserker would be spreading as though eroding the country from the edge.

Most likely it wouldn’t take five minutes until the polluted water passed through the water supply facility. The time limit until the overwhelming tragedy, was just five minutes.

「Kousuke……」

「Kousuke-san……」

Emily who was staring at the water reservoir in a daze and Vanessa who had a grim expression were calling at Kousuke.

Kousuke thought of something with a grim expression, then he suddenly smiled bitterly and strength left his shoulders. And then, he ran his gaze toward Emily and Vanessa while taking the radio into his hand.

『Bernard. I’ll do something about it. Well, it will become flashy, so don’t let anyone get near the water supply facility.』

『! Aby. Got it. I’ll leave it to you-. Please, save this country!』

Bernard’s trust and slight entreaty reached Kousuke through his voice from the radio.

The same thing was also dwelling inside the gaze of Vanessa and Emily.

Kousuke kept smiling bitterly while opening his mouth to those two.

「Actually, I didn’t want to rely on him. At the very end it become a pathetic story like this but……I’ll ask a bit, for help from his majesty the demon king.」

Emily and Vanessa looked puzzled. Kousuke’s bitter smile deepened at that.

Part 2

Kousuke and others came out to the rooftop of the clean water facility while lending a shoulder to Vanessa.

There was a water supply facility downstream, and even further downstream they could see a town.

「Kousuke, what are you going to do?」

Kousuke said「I’ll do this」to Emily’s question and he took out his smartphone. And then, he called. After a few times of the call tone, there was the sullen voice of the speaker at the other side coming out from the phone.

『……What is it, Endo――』

「Nagumo! My bad but there is no time! Don’t ask anything and blow up the water supply that is near my position!」

『……』

The call partner was his majesty the demon king who was currently spending an enjoyable time of making dinner with his beloved daughter. His majesty the demon king who was wearing the frilly pink apron that was created by Myuu for him, spending an enjoyable, enjoyable time while Yue and others were holding down their laughter!

Normally, if someone was suddenly phoned, and then requested to destroy a public facility without even getting told the reason, that person would either doubt the sanity of the other party, or they would cut off the phone without delay thinking that it was a joke before returning back to the happy family time.

But, the other party here wasn’t normal. Rather, this person was the synonym of abnormal irrationality.

Therefore,

『’Kay. Don’t move from where you are.』

「-. I’m in your debt, Nagumo!」

A presence of wry smile was transmitted from the other side of the phone.

At the same time,

「E, err, Kousuke? Who are you talking to? Or rather, what are you doing? Or rather, there are various things I want to ask but, anyway, can I ask? ――What is, that?」

「Kousuke-san……I cannot believe it but……」

Emily was looking up to the sky with a completely cramping expression while asking Kousuke, while Vanessa was also similarly staring at a spot in the sky with a flustered expression that was rarely seen from her.

Kousuke shrugged his shoulders at them who were like that and said.

「There won’t be airborne infection from Berserk. Even if it is in liquid state, but it will become invalid if it is vaporized. Then, I’ll blow it up altogether with an overwhelming heat. ――Well, that kind of thing can only be done by the demon king though.」

It was right after he said that.

Far high in the sky, a dot of light was starting to shine brilliantly as though a second sun was born. It could be seen clearly even through the cloud. It then looked like as though it swelled up instantly before at the next moment, a pillar of light descended from the sky.

The cloudy sky was blown away, an enormous hole was created at the sea of clouds in the sky, the atmosphere was burned down. That pillar which pierced the water supply facility along with a thunderous roar instantly destroyed the facility with a brilliant light, melted the ground, and created an outrageous crater at the blink of eye.

The light flooded the world.

The world that was gloomy from the cloudy sky was being dyed pure white. The heat wave and shockwave was spreading like a ripple and turned the surrounding of the facility into a circle-shaped empty land.

――Sunlight convergence laser   Burst Hyperion

The demon king detected the location of the water supply facility using “Compass of Crossing Guidance” with Kousuke as the reference point, and then he teleported the Burst Hyperion at the satellite orbit above the facility using a space substitution artifact.

Next the demon king pushed the button *kaclick*, like that. Just with that the laser cannon that converged sunlight annihilated anything and everything.

It was truly the heaven’s judgment. The manifestation of myth.

Though the person who pulled the trigger, was currently wearing a frilly pink apron at home.

「……」

「……」

The face of Emily and Vanessa turned into something that really couldn’t be shown to other people. Their eyes opened wide with their mouth gaping open unmoving. Drool was trickling from the corner of their mouth and not a single word leaked out.

While they were in the middle of being like that, the water supply facility was eradicated entirely. Next the light pillar that changed even the topography was getting thinner bit by bit, and before long it vanished as though melting into the air.

Color returned to the world and the sound of waterfall flowing into the deep crater resounded.

『How is it, Endo? Is it okay like that?』

「Yeah, thanks, Nagumo. Sorry that I suddenly made an outrageous request.」

『I understand that you are trying to not rely on me. And now someone like you came to rely on me without even saying the reason. You must a reason that is that important right? Well, I’ll trust you on that. That’s why, I ain’t need your apology.』

「Hahah. As I thought, the demon king is just too doting on his relatives yeah. That’s why I cannot rely on you too much.」

Kousuke scratched his cheek awkwardly while making a wry smile. And then, he reported that he meant to return to Japan in a few days and he would speak about the circumstance when he went back and he cut off the phone.

Kousuke let out a long exhale.

Putting aside if it was related to a request from Hajime, Kousuke had promised to himself that he wouldn’t rely on Hajime for anything in a matter that he poked his nose into by his own collision. But now he relied on him in the end. His shoulders dropped in dejection while he patted down his chest in relieve that they had avoided a great disaster (excluding the crater).

And then, his gaze slowly turned toward Emily and Vanessa who was still petrified wordlessly.

「Aa, Emily, Vanessa――」

「Hyuuwa!?」

「Afuh」

The moment he called at them, Emily jumped in surprise while raising her voice as though she was liberated from a binding curse before she became unable to stand up from shock and fell down. At the same time, Vanessa who was borrowing Emily’s shoulder also fell down and her butt impacted the ground.

Kousuke thought that their reaction was understandable while he was about to lend a hand at the fallen two――and he stiffened.

*choro choro choro~*

Slipping through the sound of the waterfall, there was sound of water from right nearby.

The source was of course, the Emily-chan who kept lying down on her butt while shivering all over. It seemed that her bladder loosened up completely from witnessing the situation that surpassed human knowledge. ‘Come to think of it, she gulped down a lot of coffee before riding the helicopter because she was nervous huuh’, Kousuke recalled.

「……Kousuke-san. It feels like I’m going to leak out too. Is it fine?」

「There is no way it’s fine.」

Vanessa who noticed Emily’s disgraceful behavior made a wry smile while talking at Kousuke. There Emily finally seemed to recover her sanity. Naturally, she also noticed her current situation――

「HiiIIIIIH. SToOOOOOP-. Or rather, DON’T LoOOOOOK-, DON’T LOOK AT THIS KIND OF ME, KOUSUKEEEE-」

Emily was on the verge of tears while tightening her bladder. She was desperately hiding with her lab coat while her hands held her head down and she turned small.

While Emily’s shriek was echoing,

『Oi, Aby! What was that just now!? Something came out there you know!? From the sky! Something came out!』

This time Bernard’s voice was transmitted from the radio. It seemed that Bernard and others also witnessed the light of Burst Hyperion.

「DON’T LOOOOOK-! PLEASE, STOPPPPPP!」

『Oi, Aby! Respond! Explanation please!』

「Kousuke-san, instead of “pi―”, the bleeding is not stopping. My wound seemed to open because of falling just now. Please help.」

Emily who screamed while turning small. Bernard who yelled together with his subordinates from the radio asking for explanation. Vanessa who was at the verge of death.

Kousuke sighed again in a different kind this time while,

「Now then, what to do about the clean-up I wonder……」

He looked up to the sky in this scene that was chaotic even when everything was over.
