What do you mean my cute disciples are Yanderes?

(MC POV)

Before I got involved with that psycho Practitioner, I had always thought my little sister to be exceptionally talented and smart.

That is… If you ignored her rather weird tendencies.

Like seriously, she had blueprints drawn up for at least ten different ways to harness natural energy before she was even of marriageable age.

No one even knew what the hell blueprints were back then.

But now I knew her knowledge came from somewhere else instead, more specifically, the world that I got sent to by that stupid stick.

Now, I'm not dumb ok? Anyone would be able to put two and two together by now to realise that the me from the past probably had something to do with the other world in some way or another.

There are quite a few possibilities right now, one of them being that this is not my first transmigration or reincarnation.

What I am more concerned about though, is who or what managed to erase away my past memories and for what reason?

You might think at this point I would make it my priority to get my memories back, but I'll just be honest and tell you that I frankly don't care about it.

I am who I am.

I already have one past life to deal with and that's already a pain in the neck.

All I wanted was to have a nice and easy life where I could just sit back, relax and let my cute disciples take care of me.

Instead of that, what do I get, huh?

My house got wrecked, my body got shrunk and now I find out my sister is a damn chuuni and a fujoshi at that.

Ok, the last part actually makes me want to regain my memories just to find out what I did wrong to make her like that, but... Nah, more trouble than it's worth.

Like I said, trying to regain back my memories would probably be just an arbitral goal that I set for myself. Then the idea will get shelved for as long as possible which would drag on for the next few decades or so until it becomes relevant again, the solution probably being some really conveniently located miracle cure or in the form of an otherworldly expert.

Ain't nobody got time for that.

I'll just live for the present, thank you very much.

Speaking of the present…

"Onii-sama! Onii-sama! Could you just please, please, onegaishimasu! Just pose like this panel here?!"

My little sister, Elaria, shoved a picture of a young boy in a heroic pose. You know, the standard hands on hips and looking up and away from the camera kind of pose.

"No," I responded almost immediately.

She then cackled fiendishly, throwing a card down on to the floor.

"You activated my trap card! With this 'Mind Trap' card, you have no choice but to obey me! Now, hurry! Hayaku!"

I don't even need to look at the card to know that it was nothing but a blank piece of paper.

"This card only applies to Practitioners which I currently am not. Also, you don't have enough mana to place down that card in the first place which means you played foul," I countered without even batting an eye.

She gasped, grasping at her chest as though something had physically struck her.

"As expected of Onii-sama! To see through my ruse so easily! Sugoi! This Magical Girl will grant you one wish for being so great!"

"Could you stop elder sister from restraining me then?"

She looked at our elder sister, Odriana, who was currently holding me on her lap. Her hand was stroking my head methodically while the person herself was ignoring everything going on around her.

"I'm sorry, Onii-sama. I'm afraid I can't do that," Elaria answered in a monotonous voice. "And don't ask me what's the problem because you know why."

I rolled my eyes at her answer, having already given up on trying to struggle out of my elder sister's unbreakable grip.

"So Onii-sama, you returned because you remembered right?" Elaria asked, her eyes sparkling.

"Didn't I already tell you my memories still haven't returned?"

"E… Eh? Uso... But… But… But you came back? That should mean you remember our promise right?"

I shrugged, "Nope, no idea what you're talking about."

Elaria scrunched up her eyebrows, "That's not right… It seems like spreading it to the town really isn't enough… I must spread the glorious 'An Ney May' to the rest of the world it seems..."

I had a feeling that correcting her about the name and idea at this point would be counter-productive.

"So… I see quite a lot has changed, huh?" I asked, trying to change the subject. "Weren't you training to be an accountant under Odriana?"

"Hmm? Does Onii-sama not know?" She tilted her head at me. "I've already taken over the company."

Huh?

"Wasn't elder brother Dailus supposed to take over the company from father?" I inquired.

Elaria nodded with a beaming smile on her face, "That was what was supposed to happen, yes. But with the knowledge that Onii-sama had granted me, I started up a proxy company outside of the family. With the new company, I introduced all the new inventions and products to the town and the capital city."

I narrowed my eyes at her, "And where did you get the capital to start up such a thing?"

Her smile turned a little devilish, "I might have commited a little fraud of some sort, but it's not like they know anyway, Onee-sama taught me how to hide my tracks."

I looked up at Odriana, discontent clear on my face.

She shook herself out of her stupor once she saw my unhappy face, "Hmm? Is something wrong? Is my cute little brother uncomfortable?"

"You've been corrupting Elaria, that's what. Teaching her how to commit fraud, what kind of respectable elder sister does that?"

"It's for the greater good!" She protested. "Besides, cute little Elaria did really well didn't she? She gathered all the bright minds together, created all the ideas that you have given her and controlled the population with new forms of entertainment to ensure the new products are more readily accepted."

Elaria nodded proudly, "Uh-huh! And with our complete monopoly over all the luxury goods and the newly introduced products, I managed to earn enough to buyout Father's company within three years!"

"And both father and Dailus were fine with it?"

"Ehehehe~ I bought them out with another proxy company that wasn't directly related to me! They suspected nothing until the whole process was completed! How is it?! Are you proud of me, Onii-sama?! Praise me! I want my mofu mofu! Hayaku!"

"Wait… So both Dailus and father…"

Elaria grinned, "They're both working under me of course!" 

Their ego definitely took a lot of damage then.

I gulped, "And… What happened to all of those companies?"

"Did another buyout and combined all the proxy companies under one big conglomerate!" Elaria boasted. "Now we are collectively known as the 'An Ney May Conglomerate'! We may be limited to this town and Jin city at the moment, but since I know that I need to spread 'An Ney May' further for Onii-sama to regain his memories now… I will definitely make it known throughout the whole continent!"

"But people will reject such sudden changes, won't they?" I cautioned.

"Don't worry about it, Onii-sama! With my followers that I have gained with my 'An Ney May' Entertainment division, the people will eat up everything I tell them!"

"Followers?"

She giggled, "That's right! Sono tori desu! They all accept 'An Ney May' as the true calling of this world! It's all for you, Onii-sama!"

This girl is definitely dangerous! She's already created a cult didn't she?!

I miss my cute disciples already…
