after you got infected with the abnormal disease, you couldn't control your body anymore, you kept shrinking in size, turning into different things so your parents took you to a trainer called Aoi, when you got there, you saw the man leaning against the desk, when he noticed you he smiled warmly and stood up

"I see you came, before we start I'd like to test something, shrink"

He said, when he said "shrink" you suddenly shrunk down to not even his foot level, Aoi observed this and hummed

"I see what your struggle is... Your body obeys other people but not you"
