Chapter 231


　A ruin that was once the stronghold of the Demon King.
　Most of the outside of the building has been reduced to rubble, and all that remains are large pillars and remnants of what was once a building.
　We entered the place where we thought Keira had come in, and the first thing we saw was a wide staircase leading to the lower level.
　Leona-san frowned at the interior of the ruins in front of her.

"I don't know what to say, but I'm going to say something commonplace, but...this is suspicious."
"...Right. Compared to the outside, the inside doesn't look that damaged...and above all, it's too bright."

　There are stone slabs that emit a white light all over the place under my feet, and the stairs below me and the walls on the sides are even more beautiful than I expected.
　It's hard to believe that this building is hundreds of years old.

"It's nice that I don't need to illuminate it with my magic, but... these stairs. Is this building structurally spread out underground?"
"It's probably going to spread underground from here like an ant nest."

　Kazuki and Senpai's words left me dumbfounded as we descended the stairs.
　There is no hesitation in Blurin's steps as he walks ahead.
　The fact that the smell remains means that Keira definitely passed through here.

"Usato, don't let your guard down. The magic power here is much stronger than outside."
『Is it really that amazing?』

　Nea on my shoulder nods strongly at the words of Ferrum, who has assimilated with me.

"To the extent that normal monsters don't even try to get close."
"...I guess there's something here after all."

　We have to find Keira quickly.
　The long staircase continued down, branching off into several passages, but Blurin ignored them and descended to the lower level, making occasional turns in the path.
　In the meantime, I've been asking Amako to predict attacks by monsters and Koga, but so far there's been no response.
　Five minutes of going down the stairs.
　Finally, the end of the stairs was in sight.

"Gruu!!"
"! Usato, Keira is just up ahead!"

　Hearing the voices of Blurin and Amako, I hurried forward while confirming that I had turned into a demon.
　At the bottom of the stairs, I found a girl, Keira, crouching down in an unnaturally large room, clutching her head and sobbing.

"... Keira!"
"...?!"

　I immediately ran over to her and checked to see if she was hurt.
　She raised her tear-stained face and grabbed onto my clothes as if clinging to me.

"I...I...I can hear...a voice...I don't know why I came here...I'm so scared..."
"It's okay now. It's okay..."
"I'm sorry...I'm sorry..."

　It must have been scary to be alone in a place like this.
　As I was trying to comfort Keira, who had started crying, and pick her up and leave this place, I heard a thud! A sound that sounded like a tremor from the ground.

"Leona-san! If we don't do something, we'll be trapped!!"
"Fuh!"

　Amako, who had predicted the future, shouted this to Leona-san, who was closest to her.
　Immediately understanding the situation, she turns around and at the same time throws her hero's spear———attempting to stop the wall that is closing the exit with the stairs leading to the ground.
　However, perhaps a moment too late, the cold-air-clad spear hits the wall and is bounced away.

"Too late, huh."

　Leona-san, who caught the returning spear, had a bitter expression on her face.
　Behind the closed wall, I hear the sound of something closing continuously.
　Accompanying it, the same earth-shaking sound as before echoes ahead. It is not the sound of something closing up, it is the sound and vibration of something ...... like a humanoid walking.

"Something's coming..."

　I jump over to where Senpai and the others are, holding Keira in my arms.

"...I guess my bad prediction came true."
"Yeah. Apparently, the purpose of the person who misled Keira and brought her here seems to be us. And this is what is commonly known as the boss's room."
"This is no time to joke around..."

　With a fearless smile, senpai puts her hand on the hilt of her sword, the hero's weapon.
　Instantly, with a tremor, some huge object falls from the ceiling.
　The huge object that fell down started moving slowly like a machine and stood up as it did. The whole thing is a large, dull-colored, humanoid object.
　Is it about 10 meters in size?
　A jewel the size of a basketball is embedded in the center of its body, its left arm is missing from its shoulder, and its right arm holds a long curved sword.

"Golem...?"

　Is that the golem Gref-san mentioned that is in the Demon King's ruins?
　No, the design is far from what I imagined a golem to be.

"Usato-kun! That's a robot! A robot from another world!?"
"U-Usato-san..."
"Keira is scared, so please stop."

　Senpai points to the golem standing there and is excited.
　Keira, who has never been involved with Senpai before, reacts with a frightened look on her face as she talks to me in her usual tone of voice.
　I sigh and put Keira on Blurin's back.

"Usato-san...?"
"Keira, maybe there will be a battle, so you stay in a safe place with Blurin and Amako. Blurin, Amako. Take care of Keira."
"Grua"
"I got it"

　When Blurin and Amako move back, a translucent ice wall created by Leona-san appears to protect them.

"Thank you"
"I don't need to be thanked for that. Better yet, we should think about how we're going to deal with it."
"...It looks like ... they're checking on us"

--- seireitranslations.blogspot.com ---

　The golem stands in the center of the room, staring at us.
　Frankly, it's creepy, but will that thing ever start moving? The next moment I thought so, and without warning, the golem took a distinctive stance, carrying a large sword on its shoulder.

"Usato-kun, it's time to stop hiding our faces."
"Yes, I understand. Let's make getting out of this situation a priority right now."

　Hearing my words, senpai removes the hood from her head.
　Along with that, Kazuki and Leona-san also remove their hoods, and I hear Keira's surprise in the back.
　However, right now we have to deal with the golem in front of us.

"I'll use ice to stop it! Using the magic of Kazuki-dono, we'll settle this quickly! Usato will support, and Suzune will act as a diversion!!"
"""Yes"""

　Following Leona-san's instructions, we each begin to move.
　Senpai, wrapped in lightning, approaches the golem at super high speed and acts as a diversion.
　The golem immediately swings a curved sword at senpai, but cannot catch her speed.

"Where are you looking? It's this way!"
"———!"

　Kazuki is accumulating magic power in his left arm to activate system strengthening.
　Leona-san is also trying to create eight ice spears on the spot in order to completely block the golem's movements.
　During that time, all I can do is support senpai who is constantly moving and hindering the movements of that big guy.
　Ordinary healing magic bullets won't work.
　In that case———,

"Nea, I'm gonna do that technique!!"
"Eh, eh!? What!? What technique!!"

　A powerful technique that can support senpai and break the golem's stance...!!
　Use the gauntlet to create elasticity magic and move it to your left hand.
　After that, create a magic bullet in your right hand, pour in the magic power, and move on to the healing explosion wave process.
　If I release it as it is, it is just a healing explosive wave ——— but I will add elasticity to it.

"Haa!!"

　By pouring in magic power, the magic bullet that was distorted and about to explode was wrapped in the elastic magic power of my left hand.
　Improvement of the healing explosion wave, which was only a strong healing magic bursting palm, so that it can be thrown...!

"Healing Explosive Wave, no! This technique that has evolved is ——— Healing Explosive Bullet!!! Nea, you know what I'm talking about!!"
"I don't want to understand, but I'm frustrated because I understand!! Here! It's the binding spell!!"
"Yoosshi!!"

　A binding spell is applied from Nea through my body to a magic bullet floating in my right palm.
　A healing explosion wave that made it possible to throw.
　This made it possible to perform wide-ranging recovery over long distances...!

"Senpai!! There will be a bit of an impact, so please be careful!!"
"I'll cut the whole impact, so it's okay! Do it!!"
"Here I go!!"
"Come ooon!!"

　After getting senpai's approval, I swing as hard as I can and throw a healing explosive toward the golem that is trying to manage to catch senpai.

"Why is Suzune not doubting Usato at all?"
『We can't understand the thoughts of crazy people, can we』

　I look at the healing explosive bullet I threw while listening to Nea and Ferrum's voices.
　Thrown at high speed, it strikes the golem's defenseless torso———instantly, a powerful shockwave spreads around the spot and the magic power of the healing magic spreads over a wide area.
　The impact causes the golem's body to tilt significantly.

"There's an opening, isn’t it!!"

　Taking advantage of this opportunity, Senpai slashes at the oncoming impact with her sword, and while repelling it, she spins once in mid-air and slams a kick, which is covered with electric shocks, into the golem's head.

"Secret Technique! Inukami Lightning Kick!!"

　The golem falls to the ground with a rumbling sound.
　Landing lightly on the spot, senpai looks surprised at the particles of healing magic that fill the area.

"Oooh! What is this?! Usato-kun! I'm recovering as I move!?"
"You can move around as much as you like without getting tired in that space!"
"That means I am invincible!!"

　It cannot be used around enemies poorly because it will cause them to recover too, but since the opponent is a golem, an inorganic object, it can be used as much as I want.
　In other words, in this battle, senpai can keep moving constantly as long as my magic power lasts.

"Suzune, she really cut the impact and stuff ... She's doing something like Usato..."
『She is an idiot, but a monster...』

　...Hmm? It looks like the binding spell isn't working... Was it destroyed in an instant?
　When I questioned why the spell did not seem to work, even though it should have been a direct hit, Leona-san released eight ice spears she had generated at the fallen golem.

"Freeze!!"

　Eight ice spears rushed toward the golem, turning it into ice and blocking the movement of its massive body.
　Once the ice covered the golem's body, Leona-san turned back to Kazuki.

"Kazuki, now!"
"Yes! System strengthening "concentration"! Goooo!!"

　Convergent light magic is released from Kazuki's left hand, which is filled with magic power.
　This is a special attack that annihilates everything in its line of fire by system strengthening. No matter how hard the golem is, it is meaningless in front of Kazuki's magic.
　The light's magic power, which went straight ahead like a beam, hit the golem directly.
　We defeated it!! The next moment I thought that———,

『Uuuuuu!!』
"Wha!?"

　The golem, which had not even made a sound until now, began to scream.
　At the same time, the magical power from Kazuki's system strengthening disappeared as if being absorbed by something, and the golem stood up as if Leona-san's ice restraints had never existed.

"The light magic was absorbed...!?"

　I am stunned by Kazuki's mutterings.
　The ice magic that was at the golem's feet had partially melted and disappeared.
　Senpai comes back to us in order to reposition.

"...A golem that nullifies magic."
"It might be quite bad if my magic doesn't work."
"My guess is that it was built for a battle with the previous generation of hero. From the few times I've slashed at it, the armor isn't half-bad either."

　The golem is once again poised to carry a large sword on its shoulder.
　The stance is the same as before, but I notice that something like a white magic bullet is beginning to generate at the base of its non-existent left arm.

"———That’s my light magic!?"
"Is it Kazuki-kun's magic power that it has absorbed! If so, that golem's next attack will be———"
『U, uuuu』

　The converged light bursts out.
　The magic bullets of light scattered as if they were splitting up, flying towards us.
　If even a single blow hits us, we will be mortally wounded ——— and Amako and the others are behind us.
　We can't avoid it...!

"Healing Explosion Wave!!"
"Inumaru Style! Discharge Slash!"

　Senpai and I were the first to react, and we sent out a shock wave and electric shock in front of us.
　The magic bullet explodes as if triggered, but still the ones that we failed to parry are closing in.

"Kuh!!"
"Usato, I will!"

　Before I could immediately release the next technique, Kazuki and Leona-san sent a magic bullet of light and a sword of ice, hitting everything down.

"W-We somehow managed to stop it..."

　I understood the feelings of the demon king's soldiers who were dealing with Kazuki, and the feelings of Kazuki, who uses light magic.
　His magic is both powerful and dangerous.

"...Let's give it a little try"
"Leona-san?"

　Leona-san, who was thinking of something, created an ice spear in her palm and threw it at the golem.
　The ice spear hit the golem, which showed no movement to avoid it, but it turned into water as if melting.

"...It seems that it only absorbs the magical power of Kazuki-dono. So, for better or worse, it is a golem specialized for fighting the previous hero."
"If light magic doesn't work, I'll have no choice but to support you."
"Yeah. Let's change tactics."

　Leona-san, who had switched her hero's spear, looked at the golem slowly approaching us and appeared to think for a few seconds before turning to me and senpai.

"All right. Usato, Suzune. You're the main players. Will you do it?"

　Senpai and I looked at each other and nodded.

""Yes!!""

　A serious co-operation with senpai.
　Although we had no prior discussions, strangely enough, I was not anxious about teaming up with senpai.
