Chapter 275


The previous chapter began from Kazuki's point of view, and this one begins from senpai's point of view.

　———I won't go back to my original world!

　When I heard those words, my mind went blank.
　I never thought that he would have been so determined at this point, and I never imagined that he would even bet his life on his ideals.

『Uoooh!』

　Usato-kun continues to swing both fists that are covered with electric shocks at the Demon King.
　The Demon King, too, has abandoned the luxury of enjoying the battle so far, and is taking his attack head-on and counterattacking with his sorcery.
　Both sides are fighting with the intention of giving it their all.
　To decide the winner of this battle———,

"So you've already made up your mind..."

　He no longer looks back, but only looks to the future.
　Unlike me, who has no regrets about my former world, Usato-kun must have friends and family he would like to see again, but he has chosen to live for the people of this world.
　I can't even imagine how much resolve that takes.

"Then I'll strengthen my resolve!"

　He probably won't hear me in the middle of a fight, but I say it anyway.
　I have no attachment to my former world.
　But if you still choose to go back to your original world, I will have no hesitation in choosing a world where you are.

"I can't live in a world where you, Usato Ken, are not ar———"
"What are you trying to declare in this confusion?!"
"Gufuh?!"

　I was hit from the side and rolled through the strange space like a tuna at a market.
　Holding my cheek with my barely moving left hand, I looked over at Ferrum, who was looking down at me with a twitching smile on her face.

"I-I was just about to make an important, heartfelt declaration!"
"Do that later! Or I'll kick you out!"
"Suzune, do your job properly!"
"Y-Yees!"

　I am the lowest in the hierarchy within Usato-kun...!
　After being scolded by Ferrum and Amako, I turned my attention to the battle and further compounded the supply of magic power that I had been working on in parallel from a moment ago.

"Usato-kun! I'm entrusting some of my magic to you! Feel free to use it to your heart's content!!"
『Yes!』

　Just as I said, Usato-kun, extending a blade of dark magic, cloaks the blade in electric shocks.
　He leapt over the Demon King's attack that slashed at his feet and swung his sword in the air.

『Lightning Healing Explosive Slash!』

　A t-technique with my element in it?!
　A crescent-shaped electric shock is fired from the blade.
　Caught off guard, the Demon King becomes shaken and uses spell to block it.

"The nightmare of tackiness is back!?"
『You're kidding me!?』

　For some reason, Nea and Ferrum screamed and Amako held her forehead, but he managed to create an opening.
　But then Amako tells Usato-kun to stop and tries to get him to back off, and he instantly notices that the Demon King, who floats a sorcery, is caging a large amount of magical power in his right arm while holding his left hand on it.

"Compound Magic, the Spell of Fire and Magic Conversion...!"

　A black pattern unfolds around Usato-kun.
　This is the same as when he used Heavenly Storm's sorcery...?
　Before I could raise my voice, Amako, who knew it by foresight earlier, raises her voice.

"Usato! Heat rays are coming! And lots of them coming from all around!"
『I'll repel them all!』

　Usato opened both his palms and lined them up vertically, waiting for the Demon King's attack.
　The next moment, a continuous stream of heat rays reminiscent of a machine gun were fired from the magic circle.

『No, this will kill us! I'll cast a resistance spell on you though!』
『No!』

　He leans forward to shield Nea, and purple electricity surrounds both his arms.
　!? He partially activated Thunder Beast (Raijuu) Mode 3!?
　No, how is that possible?!

『I will protect you!!』

　Faced with the heat rays approaching from all directions, Usato-kun's arms, which he had put up in defense, were swept away by a flash of lightning.
　In that moment, the red flashes that were approaching him bounced off randomly as if they were being bounced off an invisible wall, hitting the surrounding blocks and causing a huge explosion.
　
『———!!』

　Usato-kun deflects the heat rays with his gauntlets with incredible speed.
　After a few seconds of repeated attack and defense, Kazuki-kun's magic bullets destroy the magic surrounding him.

『Thanks, Kazuki!!』
『You're not alone!』

　Usato-kun leaps with the elasticity grant, and at once he and the Demon King come within a hair's breadth of each other.
　His gauntlet and the magic covering the Demon King's arm collide, coming so close that their foreheads are about to collide.

『We're thinking the same thing...!』
『What do you mean?!』
『That you're not like Hisago!!』
『Yep! Now that I've seen his past, I can tell you that I am not!!』

　They fling their arms at each other and slam into each other with a spinning kick.
　Usato-kun flips and lands on the ground as a reaction to being blocked, and fires a lightning bolt at point-blank range.

"Hisago-san was all alone! He worried alone, he fought alone! He shouldered everything all by himself...!"
"Because he had the power to make it possible!"

　The electric shock is neutralized, and he blocks the incoming fist with his forehead.
　He starts to step back, but then manages to push the fist back with just the strength of his neck.

『But I am only a powerful healing wizard alone! I would not have been able to compete with you by myself!』
『!』

　Usato-kun approached the Demon King at once.
　The Demon King instantly fired a heat ray at him, trying not to let that happen, but Usato-kun actually jumped into the ray, holding up his gauntlets as if to protect Nea, who was in his chest.

"Guh...! But I have friends! Friends I can trust! That's why I'm different from Hisago-san!"

　Despite receiving direct hits to his shoulder, side, and leg, Usato-kun leaps into the Demon King's bosom, wraps both of his unraveled fists in purple lightning, and strikes with an eye-popping rush.
　The magic covering the Demon King's body is instantly destroyed, and finally both fists are thrust into the Demon King's body.

"Take this! Electric Shock・Double Fist Combo!"
"Guh...!?"

　Electricity and shock waves hit the Demon King's body.
　Finally, the blow is delivered.
　The Demon King's body is paralyzed, but he immediately regains his stance.

"This is not enough to bring me down!!"
『Gah...?!』

　The Demon King slams Usato-kun with layers of sorcery and blows him up, releasing a wide variety of sorcery from the magic circle he has arranged in a line.
　A wide-ranging attack with no escape in front of him!
　Usato-kun rolled as he landed and spread his gauntleted arms wide, wrapping them in electric and healing magic.

"Healing, Fool-The-Cat Trick (nekodamashi)!" (Note: slapping hands in front of the opponent's face to confuse him)

　A Fool-The-Cat Trick imbued with magic power.
　It was supposed to be just that, but the hand that was clapped released a shockwave and electric shocks forward with a rumbling metallic sound, and blew away the magic.

『Guh.』
"Usato!"
"Usato-kun?!"

　I quickly called out to Usato-kun, who was kneeling, but his expression was not good.
　He is too exhausted from the battle so far.
　But it is the same for the Demon King.

『Not yet...!』

　Usato-kun puts his hands on his knees and forces himself to stand up, facing the Demon King.
　The battle was still evenly matched, but it is only a matter of time before the balance is broken.

　The Demon King is getting weaker.
　I can see this clearly when we are fighting.
　It is probably because he is fighting in a weakened state, and above all, the Demon King himself has not fully recovered his magic power consumed by the sorcery in the last war.
　Although it is gradual, the power of his magic is decreasing.

"...!"

　But it's the same for me.
　I thought I had managed to conserve my magic power, but I was steadily running out of it due to the fact that I had been in a series of battles up to this point.
　In the first place, the fact that he was able to take on both Senpai and Kazuki at the same time in a weakened state was simply out of the ordinary.

"Ngh!"
"Ha!"

　Fists and sorcery collide and blow each other away.
　I hit my back against the block and stare at the Demon King, who also has wounds all over his body, as he stands up.

"Stubborn!"
"That's my line!"

　Both Kazuki and I are nearing our limits.
　Kazuki, who had been showing symptoms of running out of magic power from the start, would be in mortal danger if he pushed himself any further.
　So, it's a hopeless situation where we have to fight on our own as much as possible, but we're not giving up yet!

"Haaah!"

　The Demon King isn't even activating his magic armor anymore.
　He is conserving his magic power to the point that he is redirecting the rest of his magic power into attacks!!
　Over there is in a pinch too!
　In that case, the one with the most guts and determination will win!!

『No! Usato, dodge itt!!』
"Muh?"

　The Demon King's fist pierces between the eyebrows ——— some kind of magic that emits a shock or something is hit me.
　The impact shakes my head.
　While almost falling backwards, I grab the Demon King's arm instead.

"Endure... it...!"
"How can you still stay conscious after having your head vibrated...?!"

　Using the strength of my back, I raise my torso.
　There is no way that I would lose consciousness at this level, at the degree that my head is shaken.
　Grabbling the Demon King's arm, I pull my leg back.

"You see, I! Since the day I came to this world, I was thrown into the Rescue Squad!"
"...!"
"I've had my head knocked off a few times by the Commander's bare knuckles, you know!!"

　With all my might, I slam a roundhouse kick right into the Demon King's torso.
　It feels like it's working!

"Gah...?!"

　The Demon King was kicked in the stomach and sent flying backwards.
　Just as it looked like he was going to crash into the block, his body stopped in mid-air.
　Clutching his stomach, he wiped the blood from the corner of his mouth and raised his right hand.

"———Magic Strike Spell"

　Then, something like a black magic bullet appeared in the Demon King's palm and swelled up like a balloon.
　That's, bad...!?

"This is a ball that collects the magic energy of yourself and the surrounding area. It's a magic spell with no special properties, it's just powerful. ...However, it's just something I thought I'd never use again in my life, just because it's efficient at using magical energy..."

　The magic bullet swelled into a huge sphere.
　It was clear at a glance that this was no mere show.

"This is my final big move."
"...Kuh!"
"Take it if you can."

　His raised right hand is dropped toward us.
　Immediately, I try to escape the situation in Thunder Beast mode, but my right leg doesn't move.

"Restraint Spell...!"
"It was set up when I kicked him just now? It's no good, I can't make it in time!!"

　The magic bullet has already been fired.
　If I were engulfed, I would surely be unable to fight.
　However, if I could not endure this, it would be the end.

"Healing Explosive———"

　Just as I was trying to muster the rest of my magic power to intercept it, the dark magic robe around my body transformed like a wall.
　At the same time, Ferrum and Nea appeared in front of me and I raised my voice.

"Ferrum! Nea! What are you doing?!"
"This is the only way!!"
"Yeah! This is the only option!!"

　Nea has cast a resistance spell on the wall of dark magic that Ferrum has created.
　Amako and senpai, who cannot move due to magic, appear behind me because of the assimilation being undone, but there is no way they could not know what would happen if they were to undo the assimilation in such a situation!!

"Get back here right now!"
"You'll do your best for the sake of the demons, right!!"
"...!?"
"Then we have to let you win!!"

　The magic bullets are approaching.
　Just as Ferrum and Nea prepared for the impact, Kazuki appeared next to them.
　He kneels down, catching the magic bullet with his light magic.

"I'm here too...!"
"Even Kazuki...!"
"If I'm not useful here, I can't call myself a hero?!"

　He pushed his palm into the magic bullet while spitting blood, and released his last light magic to chip away the magic bullet.
　Kazuki, who fell back, is supported by me, and this time the magic bullet crashes into the wall that Ferrum and Nea have put up.

"Kazuki!"
"Usato...!"

　Kazuki grabs my hand.
　Still in a daze, he desperately tries to say something to me.

"Not us...!"
"Eh?"
"If me and Senpai were to defeat the Demon King, it would have a completely different meaning! It would be meaningful for you, who is not a hero, to settle things with the Demon King...! So... win, Usato!!"

　After saying that, Kazuki's body went limp.
　From behind me, I hear the enduring voices of Ferrum and Nea.

"———!"

　As I tried to protect the unconscious him, Amako, and senpai, I prepared myself for the impact approaching from behind.
