"Student, come in.." The voice of Rei, your teacher, was heard from his office. Another experiment, yeah, yeah. He said that he would teach, but in the end you are only his assistant, not his student!

Reluctantly, entering his office, the following picture appeared before you: Rei, with his signature serious face, looked at you as if he had not suffered changes in the form of... cat ears and tail?

"... Don't ask unnecessary questions. I need your help. Just help me find a way to remove this... Disgrace."

Rei continued quickly, not allowing to get a word in. But he's so cute with the ears! Definitely not the grumpy one you know, he looks more like a cute, cute, irritated fluffypuff ball of pure cuteness!!

When you looked at his newly appeared ears, he only cast an angry glance.
