An Experiment Gone Wrong

//AN// In this AU, Koshi is 18 years old and attends the same college as the girls, and shares classes with Atena, But plot wise the story remains.

It was a cloudy, cool Saturday at the dormitory, and Koshi was collecting garbage to put into the trash bin, and reached Mineru's Room, and he knocked "Mineru? Can I come in?" A silence descended, so he said louder "Mineru! are you there?" then a monotone voice responded: "Yes."

A bit confused, he said, "Can I enter?" She responded in the same tone again, "Yes." he opened the door, and he saw her standing strait as a log, lab coat on with nothing else, and her eyes staring at her phone.

"H-hey Mineru are you okay?" He asked.

"Yes."

"what are you watching on your phone?"

"I was attempting to design an app that can transform, Brainwash and other things to make myself more powerful and can conduct more experiments."

"what?!" He was lost for words, the happy, bubbly scientist was actually planning to control people? he shut the door, locking it behind him, to make sure no one could enter.

"Answer this, can i get a copy of the app on my phone?" he asked, thinking of his own purposes.

"Yes."

"Can i get hypnotized by it as well?"

"if you register as the master, no."

"please add me as master."

"yes."

she pressed a few buttons on her phone, and she pointed the phone at him, which after seeing his face, turned green, and an A.I said "Master Recognized, all devices held by master will show this application."

he wasn't sure what to do, roaming the streets for most of his life, he has been through a lot of things, wishing he could control things, but now he could, but what would he do with this new found app?
