The Wrong Way to Use Healing Magic

---I'm not going back to my world!

When I heard those words, my mind went blank.

I had never imagined that he was so determined, or that he was willing to risk his life for his own ideals.

>

Usato-kun continues to swing both fists that are covered with electric shocks at the Demon King.

The Demon King, too, has left behind the margin to enjoy the battle so far, and is meeting his attack head-on and counterattacking with his magic.

Both are fighting with the intention of exerting all their strength.

To decide the winner of this battle..,

"You've already made up your mind. ......"

He no longer looks back, but only to the future.

Unlike me, who has no regrets about my former world, Usato has friends and family he would like to see again, but he has chosen to live for the people of this world.

I can't imagine how much it must have taken for him to do that.

"Then I'll be ready too!"

He may not be able to hear me in the midst of battle, but I will say it nonetheless.

I have no regrets for my former world.

But if you still choose the original world, I will seek it without hesitation.

"I don't know if I can stand a world without you, Usato Ken..."

"What are you trying to declare in the confusion?

"Gufu!"

He is hit from the side and rolls around in the strange space like a tuna fish in the market.

Holding my cheek with my barely moving left hand, I looked over at Ferrum, who was looking down at me with a wry smile on his face.

"I was just about to make an important declaration of preparedness!

"You can do that later!　Or I'll kick you out!"

Susanne, do it right!

Yes, sir!

I'm the lowest in the hierarchy of Usato-kun ......!

Ferrum and Amako chastised me, and I turned my attention to the battle, further complicating the supply of magic power that I had been working on in parallel earlier.

"Usato-kun!　I entrust you with a part of my magic!　You can use it as much as you like!

>

Just as I said, Usato-kun extends a blade of dark magic from his arm with a jerk, and the blade is covered with electric shocks.

He leaps over the demon king's attack, which seems to reave him off his feet, and swings his sword in the air.

>

Wow, a technique with my element in it!

A crescent-shaped electric shock is released from the blade.

The demon king, perhaps caught off guard, prevents it with his sorcery.

The nightmare of "Dasa-sa" is back!

>

For some reason, Nair and Ferrum screamed, and Amako held her forehead, but they were able to create an opening anyway.

But then Amako tells Usato-kun to stop, and as she tries to get him to back off, she instantly notices that the Demon Lord, with his left hand on his right arm, is instantly filled with a large amount of magical power as he floats a magic spell.

>

A black pattern unfolds around Usato-kun.

This is the same as when I used the Tenrashi spell ......!

Before I can raise my voice, Amako, who knew this before, raises her voice.

"Usato!　Heat rays are coming!　And lots of them from all around!"

<>

Usato-kun, his palms open and held vertically in a line, awaits the Demon Lord's attack.

The next moment, a series of hot rays, reminiscent of machine guns, shoot out from the magic circle.

>

<>

He half-swallows as if to protect Nair, and both arms are covered with purple electric shocks.

What?　He partially activated Thunder Beast Mode 3!

No, how is he able to do that?

<>

Faced with heat rays coming from all directions, Usato's defensive arms scramble away along with Shiden.

At that moment, a red flash approaching him bounces off an invisible wall at random, hitting the surrounding blocks and causing a large explosion.

>

With unusual speed, Usato bounces back the heat rays with his basket hand.

After a few seconds of repeated attacks, Kazuki's magic bullets destroy the magic surrounding him.

>

>

Usato-kun leaps with his elasticity and comes very close to the Demon King at once.

His basket hand and the magic covering the Demon Lord's arm collide with each other, coming so close that their foreheads are about to collide.

>

>

>

>

They fling their arms at each other and kick each other in the arm.

Usato-kun is blocked and lands on the ground, flipping over as he recoils, and fires an electric shock at point-blank range.

>

>

The electric shocks are canceled out, and he catches a fist with his forehead.

He starts to back away, but then, of course, he pushes the fist back with just the strength of his neck.

>

<>

Usato-kun approaches the Demon King at once.

The Demon Lord, however, dives into the heat ray while holding a basket hand as if protecting Nair who is in his chest.

<>

Despite taking direct blows to the shoulder, side, and leg, Usato-kun jumped into the Demon King's bosom and clad both of his unshackled fists in purple electricity and delivered a blinding rush.

The magic covering the Demon King's body is instantly destroyed, and he thrusts both fists into the Demon King's body.

>

>

Electric blasts and shockwaves are sent into the Demon King's body.

It was a blow after all.

The Demon King's body is paralyzed, but he quickly regains his posture.

>

<<>

The Demon King, who had struck Usato-kun with many layers of magic and blown him away, unleashed a wide variety of magic from the magic circle he had arranged in a line.

A wide range of attacks with no escape in front of you!

Usato-kun rolls and lands on his feet, his hands wrapped in baskets and spread wide, covered with electric shocks and healing magic.

>

A cat trick with magical powers.

It was supposed to be just that, but the clapped hands sent shockwaves and electric shocks forward with a rumbling metallic sound, blasting away the magic.

"Usato!"

Usato?

I call out to Usato-kun as he falls to his knees, but his expression does not look good.

He is too exhausted from the battle so far.

But so is the Demon Lord.

>

Placing his hands on his knees, Usato-kun forces himself to stand up and faces the Demon King.

The battle is still raging, but it is only a matter of time before the balance is upset.

The balance is only a matter of time before it is lost.

The Demon Lord is weakening.

I can see it in the battle.

It is probably because he is fighting in a weakened state, and more than anything else, the Demon King himself has not fully recovered the magic power consumed by the magic in the last war.

The power of his magic is gradually decreasing.

"......ッ"

But so am I.

I thought I had managed to conserve my magical power, but I was steadily running out of it due to the fact that I had been fighting so many battles in a row.

In the first place, it's too much to be able to take on Senpai and Kazuki at the same time in a weakened state.

"Nun!"

"Ha!"

Fists and magic collide, and both are blown away by each other.

He slams his back against the block and stares at the demon king, who is also wounded to the bone, as he stands up.

"He's stubborn!

That's what I say!

Kazuki and I are both nearing our limits.

Kazuki, who had been showing symptoms of running out of magic power, would be in mortal danger if he exerted himself any longer.

So we have to fight alone as much as possible, even though we are in a desperate situation!　But my heart is not broken yet!

"Huh!"

The demon king hasn't even activated his magical armor yet.

He's saving his magic so much that he's using the rest of his magic to attack!

They are in trouble!

Then, the one with more spirit and determination will win!

>

"Hmm?"

The Demon Lord's fist is between your eyes... and you're hit with some kind of shockwave magic.

A shock that shakes your head.

You almost fall backwards, but you grab the Demon Lord's arm.

"I'm ...... proud of ......!"

"You're still conscious when your head is vibrating ......?

He raises his upper body only by the strength of his back.

There is no way that I will lose consciousness just from having my head shaken like this.

I grab the demon king's arm and pull my legs wide.

"I am!　From the day I came to this world!　I was thrown into the lifeguard squad!

......!

So I've had my head shaken so many times by the commander's fist!

With all his might, he slams a right kick into the demon king's torso.

It feels good!

"G......!?"

The Demon King is kicked in the abdomen and blown backward.

He stops in mid-air, as if he is about to crash into a block.

He wipes the blood from the edge of his mouth while holding his abdomen, and points his right hand upward.

"---Magic of the Demon King."

Then, a black magic bullet-like object appeared in the Demon Lord's palm and swelled up like a balloon.

That's not good. ......!

"This is just a ball that collects magic power from itself and the air around it. It is a magic without any characteristics, just a powerful magic. It's just an ...... efficient magic that I thought I'd never use again in my life. ......"

A magic bullet that swelled into a giant sphere.

It was obvious at first glance that it was not something that was just for show.

"This is the last big move!"

"......ck!"

Take it if you can!

A raised right hand is dropped toward us.

He immediately tries to escape the situation in Thunder Beast mode, but his right leg does not move.

"Binding spell ......!"

It was set up when I kicked him earlier!　No, we can't make it!

The magic bullet has already been released.

If he is swallowed, he will surely lose the battle.

But if we don't hold them off, it's over.

"Healing explosion!"

Just as I was about to use my remaining magical power to intercept him, the dark magic robe around my body transformed like a wall.

I screamed out in anger when I saw Ferrum and Nair appear in front of me.

"Ferrum!　Nair!　What are you doing?

It's the only way!

Yes!　It's the only way!

Nair is casting a resistance spell on the wall of dark magic that Ferrum created.

Amako and her senpai, who can't move due to magic, appear behind me because of the assimilation being broken, but there's no way they can't see what will happen if the assimilation is broken in a situation like this!

"Get back here, now!"

You'll do it for us demons, won't you!

......?

Then we have to let you win!

The magic bullet is close at hand.

As Ferrum and Nair prepare for the impact, Kazuki appears beside them.

He kneels down, catching the magic bullet with his light magic.

"I'm here too, ......!"

Kazuki to ......!

What's a brave man if he's not useful here!

He pushes his palm into the magic bullet while spitting up blood, and then releases his last light magic to chip away at the magic bullet.

Kazuki falls back, and the magic bullet crashes into the wall that Ferrum and Nair have put up.

"Kazuki!"

"Usato......!"

Kazuki grabs my hand.

He is trying desperately to talk to me in his foggy consciousness.

"It's not us. ......!"

"What?"

"If me and my senpai defeat the Demon King, that's not what it means!　It means that you, who are not a brave man, are the one who's going to settle things with the Demon King. ......!　So ......, win, Usato!"

Kazuki's strength drains from his body as he says this.

Behind him, he hears the enduring voices of Ferrum and Nair.

"---!"

I prepared for the impact coming from behind me, protecting him, Amako, and my senpai, who had fainted.
