The Dual Swordsman Who Lost Both Arms On Stream to Save His Doomed Party Gets Exiled—Then the Heroines Go Yandere

Chapter 19: Rehab and Delinquent Hunting

――――【Nezha’s Perspective】

“Whew… this should do it.”

New metal arms, gleaming dully in silver, were now attached where my old arms used to be. Hayase Shima let out a sigh, as if she had just finished a big job.

To a kid like me, even the breath Hayase Shima exhaled felt somehow seductive.

“Okay, try moving them a little.”

I did what Hayase Shima said and, still lying in bed, focused on moving my fingers. The orichalcum worked into the fingers glowed fluorescent green. It reminded me of that famous sci-fi robot anime where the frame reacted to thoughts.

My fingers twitched.

“As expected of Nezha. I’m impressed. This isn’t something you can just move right after putting it on.”

Really? I was surprised.

The way to control them was almost exactly the same as God’s Invisible Hand.

When I clenched my fingers hard into a fist, it felt like I could easily crush an apple with my grip strength.

I sat up, and the weight of the arms made it sink in. These were my new arms… Though I called it weight, they seemed to be made light and strong, like titanium alloy.

“How is it? How does the new arm ‘Armada’ feel?”

Compared to God’s Invisible Hand, it seemed I would need rehab to control it delicately. While I was clenching and opening my fists in front of my chest, Hayase Shima asked.

“Yeah, I can only say it’s the best. After all, Hayase Shima made it for me. It can’t be bad.”

“Nezha…”

Hayase Shima hugged me tightly. Her heartbeat came through my skin so strongly…

“When I heard Nezha had lost both arms, I couldn’t stay calm… And on top of that, being wrongfully accused and expelled from school, I was so worried… Do you know how close I came to losing my mind?”

“Sorry, Hayase Shima…”

I put my hands on Hayase Shima’s back and touched her skin through her clothes.

“But that’s all over now. With Armada, you and I are connected by an even stronger bond. So let’s get married.”

“How does that follow, Hayase Shima…”

Even though it was a metal frame, how could I feel Hayase Shima’s softness and body warmth?

“Hehe, touching me made you want to hold me, right? It did, so be honest.”

“That’s not it. I felt Hayase Shima’s softness and body warmth even through the prosthetic… so Hayase Shima used orichalcum…”

“Yeah, good catch. The AI-controlled prosthetics that Tōto pushes aren’t bad. But they can’t let you feel human warmth. That’s why I insisted on making prosthetics with orichalcum.”

“Could that be why Hayase Shima got kicked out of Tōto…”

A genius engineer, like me, falsely accused and exiled.

“It’s in the past. I’m happy just being able to spend time with Nezha like this. In that sense, I should almost thank them.”

“But…”

“A kid shouldn’t worry about adult things. It was just about vested interests. Using AI and machines moves more money. That’s what they wanted. If you dig too deep, Nezha will get dragged into unnecessary trouble too.”

Getting involved with the Amiro family already feels like being dragged in…

“To celebrate Nezha getting new arms. Let’s do it!”

“Hayase Shima, you’re too direct.”

“It’s fine if you don’t want to. I won’t force you. But Nezha seems pretty pent up too?”

“N-no, I’m fine. I can’t trouble Hayase Shima’s hands any more… wait, why are you loosening my belt…”

“I’m Nezha’s big sister. Just give in to your desires without holding back.”

“No big sister lets anyone do that… ngh!”

“Hehehe, you talk a lot, but your body is honest. Oh, it’s getting hard. Wonderful hardness, no less than Armada.”

“W-wait, wait! Hayase Shima!!!”

Without both arms, I couldn’t even use God’s Invisible Hand to take care of it myself. Afterward, all the desire that had built up was drained out of me by Hayase Shima…

Hayase Shima sat on the edge of the bed in her black lace bra and wiped her mouth with a handkerchief.

“Earlier you said the Exploration Department was abolished. Actually, it still exists. The department is gone, but some students keep it going as a club. Though it’s pretty much inactive…”

“Are you in the Dungeon Exploration Association?”

“Yeah, of course.”

The Dungeon Exploration Association is short for that, an external bureau of the Cabinet Office. They handle permission applications for dungeon exploration, and unlicensed groups aren’t allowed to dive into dungeons.

After school, I stood in front of the club room with a nameplate that read Labyrinth Club. The outer walls and door were covered in tasteless spray paint art, and illegal dumping like tires, refrigerators, and microwaves was scattered around.

I had thought this was a school with decent standards, but only around the exploration club did it feel like a post-apocalyptic wasteland.

Since there was a club related to dungeon exploration, I steeled myself and knocked on the door…

“Huh? What? We ain’t recruiting members. Get lost, trash.”

Out came someone who looked every bit the delinquent.

“Wait wait! Haha! This guy’s famous!”

“Yeah, I saw him on a dungeon stream! The idiot who bragged about soloing a raid boss and lost both arms!”

“The moron came back to dive in dungeons. Idiots really never learn.”

“””Hahahahahahahahahaha!!!”””

I was surrounded by three delinquents who had come out of the door…

“W-welcome… p-please come in…”

A faint voice came from inside, so I ignored them and went into the club room.

“Ignoring us—guh!”
