What do you mean my cute disciples are Yanderes?

(MC POV)

As if anyone was expecting any different, our group had chosen to have lunch on the school rooftop because of course we would.

I mean, where else would a bunch of high school students go to eat lunch, right?

We had a picnic mat spread out on the floor and for some reason or another, there was no wind blowing today that might mess everything up.

Of course, even if there was, it wasn't anything I couldn't fix.

"As usual, Onii-san's bentos look way too good…"

"Guhihihi~ It's handmade by Aniue so of course it'll be good!"

"Heeeeh~ Can I trade your omelettes with my sausages?"

"That's hardly a fair trade, you know, Tamako-chan?"

"Ghkk… But there's nothing I have that's the same value as Onii-san's food…"

"Heh heh, Aniue's food is all mine~"

I cleared my throat and pushed my own bento box towards them, "You can have some of mine, Maeda-kun."

The girl who had been trying to get Tsuki to share her food with her gasped, "Really?! I will really take them, you know? Is that really alright, Onii-san?!"

Tamako Maeda, the last of Tsuki's close circle of friends. An aspiring art student who likes to draw and read manga though her drawing was honestly rather subpar. I know for a fact that her dream never came to fruition because of her lack of talent so she ended up being a normal office worker in the future. She's also part of the reason why Tsuki likes anime so much.

I nodded and she immediately went to take some without reservation. For some reason, Tsuki, Fujiwara, and Nishimura also came forward to take some of my food too.

Geh… They took all of my fried chicken… I wanted those…

"Say, isn't the student council president elections starting soon?" Maeda commented after enjoying a big piece of my fried chicken.

Nishimura tossed the piece of sausage he managed to nab from my box into his mouth, "Don't we all know who is going to win anyway? The other candidate is pretty much a side show."

Fujiwara rolled her eyes, "That self-important idiot Takeda huh? I can never understand what's so special about that guy. Is it just because his family has a little bit of money?"

"You have to admit he does have the ikemen look, no homo though," Nishimura added quickly.

Tsuki's eyes gleamed, "Amnuieh weelth ween!"

I smacked her on the head, "What did I say about talking with your mouth full?"

She took a second to swallow the food in her mouth before turning back to me, "Aniue should join the election! Aniue will be the best student council president in the history of student council presidents!"

I shook my head, "Nah, that's not going to happen. I already have two businesses to take care of so I don't want to add a third  one to my list."

Nishimura raised an eyebrow at me, "Didn't Onii-san say you had capable people taking care of things to the point you have nothing else to do?"

Grrr… Can't you take a hint you baseball junkie?

"Even so, there's still things only I can take care of, so I can't take on any more responsibilities," I lied.

"It's a shame though," Maeda muttered wistfully. "He said that once he becomes student council president, he's going to put a ban on having people wait outside the school for students 'for our safety'. Not that it really matters to--"

"WHAT?!" Tsuki screached, startling all of us.

"What's wrong, Tsuki?" I asked.

"That's unacceptable! How can he do this?! What about Aniue?! Does he intend to stop Aniue from waiting for me at the school gates from then on?!"

I looked at my little sister incredulously, "Tsuki? Did you forget I'm your classmate now? I don't need to wait for you at the school gates to pick you up anymore."

"That's not the point, Aniue! He's vilifying one of our sacred traditions!!"

The sacred tradition of me waiting for you at the school gate? How is that even a thing? Is she ser-- Oh, she's definitely serious about this.

"I mean, isn't it fine? It doesn't really concern us anymore," I pointed out.

"It does, Aniue! He's basically painting Aniue as a villain for having a history of doing such a thing! If, in the future, someone were to wonder why this rule was even implemented, they would see Aniue as one of the perpetrators and mistake Aniue as a villain! I won't allow Aniue's name to be tarnished like that!!"

At this point I'm just staring at my little sister with my mouth hanging slightly open in disbelief. Was this the reason why she competed for the student council president position in the previous time too?

How did she even come to this conclusion? I'm pretty sure no one would even care and that Takeda boy was most likely thinking about the students' safety by implementing this rule.

Not that it's a good rule in the first place but still…

Nishimura clasped my shoulder empathetically, "Give up, Onii-san. Whenever she becomes like this, nothing can stop her. Especially if the matter involves you."

Well, I know that side of her first hand but… I didn't think it would be this serious.

Tsuki turned to me, fire burning in her eyes, "Aniue! You should run for student council president! We will definitely support you!"

"No," I told her simply, going back to eat my lunch.

"Fueee? Why Aniueeeee…" Tsuki wailed while grabbing my arm, suddenly acting like the spoiled little sister she was.

"For one, I'm older than you all so it wouldn't be right for me to take away something that should belong to someone in your age group. The student council president should also be someone who knows the school well and I clearly don't fit the bill. Secondly… It's too troublesome and I don't feel like it."

"Ahahaha! Onii-san has a point though," Nishimura laughed. "It might be ok with us but I think the rest of the school might not take it well. Not to mention the fact that it's basically going against tradition."

Fujiwara giggled, "Heh, most of the boys would definitely object. But the girls definitely won't have a problem with it~"

"That's right, that's right!" Maeda agreed, nodding her head sagely. "So how about it, Onii-san? You'll definitely win by a landslide if you do run for it."

I shook my head, "Not happening."

"Oh come on Onii-san! You're a much better choice than him, right Tsuki-chan?"

Tsuki shook her head, "No…"

"That's right, so why not… Eh? No?"

My little sister nodded, "I've been thinking about this wrong. Aniue shouldn't be the one who needs to bother with such a problem. I should be the one to do it! I will run for student council president instead!"

Ah… There it is, my cute little sister's going to be the student council president. At least this part of the timeline isn't going to change.

And since my little sister already declared that she's going to do it, I would of course support her as her elder brother, right?

It's definitely not because I find her cute as student council president. Definitely not at all.
