I was to fight with the demon king who had become my familiar.

We promised to fight again.

My classmates and students are lying on the ground.

“What? Why did they faint?”

The Demon Lord is now in human form, and his magical power should be significantly suppressed.

“I am simply too strong. The average person will do this at the mere sight of me. Now… let the games begin.”

The silver-haired beauty’s amethyst eyes blazed.

A moment later, the demon king was right in front of me.

I made a sword with [Creation] and parried the fist she threw at me.

“Hahaha! Good! Good!”

Venomzard’s fist is bounced off, and she flies into the air with great force. But she immediately stops in mid-air. She levitated by using [Fly].

“Looks like your swordplay is as good as always,” said Venomzard.

I jump up and slash at her.

Gaghiiiiiiiiiiiiiiiiiiiiiiiiiiin

My sword and the Demon King’s fist collide.

The impact obliterates her right arm.

“What destructive power! Yes! This is the sword of the hero!”

With [Regenerate], she immediately restores her right arm.

The Demon King then unleashed a thousand fists.

Dogga-ga-ga-ga-ga

“A thousand blows at the same time! How could you easily avoid this unavoidable attack? I knew you were the best!”

As expected, I noticed something strange. I said while floating in the air with [Fly].

“Hey, Venomzard.”

“You can call me Vena.

“Well then, Vena. You aren’t holding back, right? Even though you’re restricting your magic power, you’re still too weak.”

2000 years ago, we were almost entirely even.

But now, I had completely surpassed her.

“What, you don’t realize it? There is a [Magical Pathway] between you and me.”

“Magical Pathway?”

“It is a spiritual line that connects summoners and familiars. Through this, they can pass the magic power to each other. In other words, you have obtained the power of a hero but also the immense power of the Demon King.

“Oh, is that so?”

The heroes and the Demon King are evenly matched. With the power of both, you are twice as strong as you were before your reincarnation.

“I don’t really feel it yet, do you?”

“Then let me test you against my full strength!”

Crack

Venna’s body glows black.

The evil dragon Venomzard, the Evil Calamity Dragon Emperor, has revealed itself.

The restricted magical power surged like a storm.

“Let’s fight seriously, hero.”

Vena strikes me with its wings and breath attacks.

Byo-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh-oh!

A raging storm comes toward me, gouging the ground.

I strengthen my body with my Fighting Aura.

Even though the storm hit me, my body was not injured.

Carelessly, I swat it away with my right arm.

Pang

The storm that had been raging earlier was instantly obliterated.

“With the addition of the demon king’s power, you’ve gained more than twice the strength and physical strength you once had!”

The demon king seemed really happy that the hero had become stronger.

The evil dragon lunged at me with divine speed when I let my guard down.

I caught the tip of the dragon’s nose with my right hand.

Doggo-oh-oh-oh-oh-oh-oh-oh-oh

A shock hits my body. If it had been before, it would have shattered.

But my body was unaffected by it.

“You are unscathed by the full-force rush! Amazing!”

“What? That was full power?”

“I like your attitude toward the Demon King’s full power! That’s what makes you the master of the Demon King!”

Vena moves away.

Her mouth is filled with the full force of the dragon’s breath, and her entire body is covered with the dragon’s breath.

The mouth is filled with all of its magical power.

It was the strongest ray of destruction that I, the hero, once suffered from.

“I’m not sure if this is a good idea! Let’s go, hero!”

Bigooooooooooooooooooooooooooooooooooooooooooooo

The dragon’s breath instantly reduced the vast forest within the school grounds, not to mention the school grounds, to nothing.

It was not too fast, yet its power was immense.

The trajectory of the attack was clearly visible to my eyes.

The demon king’s magical power that filled my entire body must have raised the level of my abilities as a hero.

With my super-enhanced physical strength, I swung my sword.

Zzzaaaaaaaaaaaaaaabbbbbbbbbbbbaaaaaaaaaaaaaaaaaaaan

I struck the dragon’s breath head-on.

The slash cut the evil dragon in half.

Mhm! You’re the hero!”

The evil dragon’s transformation was released, and Vena fell to the ground in a heap.

“As expected of the Demon King, I can’t believe you’re still alive after receiving that blow.”

“You are the strongest man in history, after all. I am delighted to be your familiar!”
