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

Chapter 15: Reunion with the Admired Big Sister

――――【Nezha’s Perspective】

Hayase Shima had made up some excuse about me feeling sick halfway through the day and brought me to her territory, the nurse’s office.

I figured a school nurse wouldn’t do anything strange on campus, and with the nostalgia kicking in, I ended up following her.

“Eh!? Th-this is…”

“What’s so surprising? In a school with a department related to dungeon exploration, this is normal.”

Once inside, it looked less like a nurse’s office and more like a clinic—no, like some cutting-edge medical facility.

The space was about the size of three classrooms. The left side had hospital beds, the right looked like an operating room, and only the center area where we stood now felt close to a regular nurse’s office.

“But wasn’t this shut down?”

“It costs a fair amount to dismantle everything. Besides… I asked them to leave it for my research.”

I’d heard that Hayase Shima held a medical license, a teaching license, and even a doctorate in mechanical engineering—she was a real genius. Too smart, maybe, since she lacked the ethics to keep from going after an underage guy like me.

At her urging, I sat down. The sink area in the nurse’s office was set up like a small kitchen, and as steam rose from the electric kettle there, Hayase Shima poured hot water into a cup.

She brought it to the table in front of my seat, but her hand stopped midway.

“Well, we have a lot to catch up on. Drink some coffee. Oh, right—you don’t have hands. Sorry about that.”

“It’s fine. I’m used to it by now. Just set it down there… hey.”

As I leaned forward to take off my shoes, something blocked my view. Hayase Shima’s full chest was pressing against my face.

“Hayase Shima, that’s hitting me.”

“Yeah, I’m doing it on purpose.”

“You’re holding boiling water—that’s dangerous.”

“Right. If it spills and scalds us, we’d both have to take our clothes off.”

Hayase Shima was the same as ever, always steering things in a weird direction.

“Oh, I almost forgot something important. Compared to when Nezha lost his virginity to me, my breasts have grown about twenty percent. Don’t you think they’re even better to touch now?”

“No, I don’t.”

She squeezed them herself with soft thumps to show off. They’d been big even when I was in middle school, but this wasn’t the kind of thing to do in front of a healthy student.

“Unfortunately, though, I don’t produce milk. So milk coffee is off the menu today. But if Nezha wants to see my breasts again—even if he’s tired of them—I can demonstrate adding the milk?”

“The unfortunate one here is you, Hayase Shima.”

Hayase Shima struck that pose foreigners do when they’re exasperated, turning both palms up.

That just makes it look like I’m the one being exasperating!

“I’ll feed it to you. Nezha, just sit there.”

“Wait, why are you the one drinking it?”

Hayase Shima brought the cup she’d been about to hand me to her own lips and took a sip of the coffee.

“Is this for a mouth-to-mouth feed?”

“If that’s the case, I don’t want it.”

When I refused, Hayase Shima swallowed the coffee and leaned in closer to me.

“What’s wrong? We’re way past being shy with each other.”

She was smart, beautiful, had an amazing figure, yet turned down every marriage proposal that came her way—all to obsess over someone like me.

I got fed up with Hayase Shima’s excessive need for skinship and started to stand up. Hayase Shima got startled and lost her balance.

“Whoa!?”

Her heel slipped, and as Hayase Shima started to fall on her backside, she was still holding the cup of boiling coffee—if she went down like that, she’d get badly burned.

Make it in time!!!

【God’s Invisible Hand Invisible Arms】

When I activated the skill, invisible arms appeared that no one else could see and supported Hayase Shima’s back and the hand holding the cup.

“What? What happened? I just lost my balance and was about to fall. But here I am, standing in front of Nezha. Still, getting Nezha to drink this coffee comes first.”

Good.

She didn’t notice I used 【God’s Invisible Hand】.

“How is it? Is the coffee I’m feeding you good?”

“Yeah, thanks. It’s deli…cious… Wait, why am I suddenly so sleepy…”

Even though it was daytime, my eyelids grew heavier and heavier, and my body swayed back and forth.

“Good night, Nezha. You’re just too good a boy…”

Before my eyelids fully closed, Hayase Shima whispered that to me.

I woke to the sound of a machine measuring vital signs. When my consciousness returned, I was lying on what seemed like an operating table, my upper body bare.

What!?

“Good morning, Nezha.”

Lowering my gaze further, I saw Hayase Shima straddling my waist.

“Hayase Shima!? What’s this?”

“You’ve changed so much. It’s completely different from middle school. You’ve gotten so strong… I’m falling for Nezha all over again.”

She stroked my chest lovingly. The soft feel of Hayase Shima’s hands felt good, and my lower body started to react with excitement.

“Getting excited over someone like me again—Nezha really is kind. Just like I thought, Nezha is a tsundere.”

“No, that’s not—I’m not into this kind of thing…”

“You held back. When I found out Nezha was dating Yuki. But you don’t have to worry about Yuki anymore.”

“You knew about that…”

“Of course. I’m Nezha’s stalker, after all…”

It happened as Hayase Shima licked my neck.
