The training in the infinite prison was very hard and there were many times I wanted to run away.

I almost died every day, Tess Onee-chan and Rio were relentless, and I came close to crossing the Sanzu River many times.

Nt: It is believed that on the way to the afterlife, the dead must cross the river, so Japanese funerals include placing six coins in the coffin of the deceased.

And there are two reasons why I was able to continue.

One, because I could feel it made me stronger.

His instructions were very precise and there was no waste. Because of that, even a quitter like me was able to get stronger and stronger.

I may be slower than other people, but it doesn't matter.

I was very happy to be able to grow, even if it was little by little.

And the second reason is because of my mentors, Tess Onee-chan and Rio.

At first I was scared and afraid of them, but as I spent time with them here, we became friends and now they are like a real family.

When I was training, Tess Onee-chan was a ruthless instructor, and she almost broke my heart many times. But when the training was over. Her attitude changed to that of an Onee-chan and she pampered me as if I was a younger brother.

Even one day when I was falling asleep, I called her "Onee-chan".

For some reason Tess Onee-chan had blood coming out of her nose and fainted. I worried that she was dangerously ill, but Rio said; "she's sick in the head, leave her alone." Shouldn't I worry about something like that?

As for Rio, she feels like she is a very dear friend.

She loves to make jokes and usually plays with me a lot.

And every time she does it, she brings her body very close next to mine, and it's something that always makes me nervous. I once said it to Rio, for which she responded with a, "Ho ho... You're such a little pervert!!! Are you lusting after a body like mine?"

Rio has the appearance of a little girl, but from my point of view, she is an attractive woman.

I tried to explain calmly, but Rio's face turned red and then she got angry at me, so she wouldn't listen to me.

They both possess inhuman strength, and even though I have spent so many centuries training to become very strong, I don't think even the current me can beat them.

In spite of everything, they were not bad people, they were just normal girls who felt hurt and lonely.

And for those reasons, I decided that I was going to do what I could to get them out of here.

Of course I don't plan to break my promise, but I wanted to save them because I wanted to, not because I want to keep that promise.

But in order to do that, I have to say goodbye to both of them.

It's hard to say goodbye to two people who are like family to me. It's hard, but... It is necessary.

It has been decided that I will leave here tomorrow, because tomorrow is the day when the aberra's power goes down for a certain cycle.

So today we will take a rest day to prepare. I am now resting in my room that Tess Onee-chan created with her magic.

It has been a long time since I had a day where I did nothing. It's been 300 years where every day I was giving my all to become strong, so it's kind of strange to be able to rest.

Thinking about these things makes me sleepy....

"Huh..."

I tried to fight the drowsiness for a while, but then I thought I wouldn't have anything to do, and fell asleep....

Muriuri.

"....Hm?"

I wonder how long it's been since I started sleeping.

I wake up to the sensation of a soft object hitting my body.

What the heck is this? I thought as I rubbed my sleepy eyes.

"Kyan ♪"

....Hmm?

That voice sounded familiar.

I opened my eyes in fear, and there she was, Tess Onee-chan, hiding on my futon. She was wearing an unusual outfit, she had a black nightgown that was too stimulating to my eyes, it left a lot on display.

"Wha...!"

"Good morning, Lucious-kun♪ I was very surprised that you touched my breasts♪"

After hearing those words, I realized that I was squeezing Tess Onee-chan's big breasts, and I hurried to remove my hands.

They were so soft!

I mean... why is Tess Onee-chan here!

I tried to get out the other side of the futon, but to my surprise, there was someone else crawling in on the other side!

"Fufu, don't even think about it. Do you think you can escape the Demon King and Dragon King's siege?"

It was Rio who was on the other side of the futon, and just like Tess Onee-chan, she was wearing a very sensual pink frilly underwear.

I know Tess Onee-chan has been up to naughty tricks, but why is Rio playing along with her!!!!

Normally she'd be the one to stop Tess Onee-chan from doing something like this!!!!!

"W-What's wrong with you guys, wasn't today supposed to be a day to rest!!!"

As much as Tess Onee-chan and Rio had a pleasant smell that put all my senses to sleep. I tried to withstand the temptation.

Then Tess Onee-chan starts talking while staring at me with warm eyes.

"Rio and I were talking, and we were wondering what we could do to properly say goodbye to Lucious-kun."

"O-Oh..."

"We've already strengthened you to the limit of what your current body allows, and we've also provided you with a lot of knowing. But we thought it's still not enough, and we wanted to give you something more."

"A-And that is...?"

When I asked fearfully, Tess Onee-chan hugged me tightly and whispered in my ear.

"Our... Virginity♪"

"!!!!!!!"

Followed by that, Tess Onee-chan puts her lips on mine.

It's not the kind of kiss you give to a brother or sister, but a passionate kiss like that of a lover.

After Tess Onee-chan kissed my lips for a few minutes, she was completely satisfied and pulled her tongue out of my mouth.

Ahah...

That feels really good... I thought she was going to suck my soul.

"Hey, don't get distracted, it's my turn now."

"Eh? Mugh!"

Followed by Rio grabbed my head and turned it forcefully to where she was, and kissed my lips as well.

Rio's kiss was rougher than Tess Onee-chan's. It was complicated to describe, and I felt like I was going to be crushed with anguish. And, for some reason, being made to do it by a child younger than them is very exciting to me.

"...Fueeh. So this is what it's like to kiss someone. It's harder than it looks."

"Hoho, Rio, your face is a nice shade of red."

"Sh-shut up!!! You think you're so experienced, but you're just a virgin!"

"Huh, what's wrong with the Demon King being a virgin, Rio, you idiot!"

"Maybe it's because you're getting old?"

I tried to escape from the bed while the two of them were yelling at each other.

But when I was almost about to get out, they grabbed me by both shoulders.

And then I'm pulled into the center of the bed.

I feel like a fish on the cutting board, waiting to be eaten.

"He... Hey... Is it possible that you could treat me kindly...?"

"That's impossible."

"No, I can't."

Both girls smiled as they said that, and then pounced on me.

Oh, heavenly father and mother.

Today, I have become a man.
