Yin Yalan is a violent maniac with abnormal brain. Her creed is: there is no problem that cannot be solved with one punch. If there is, just use two punches.
During a cordial conversation with a delinquent boy from another school, he was bound to a transformation system, and his journey to find truth, goodness and beauty began.
Yin Yalan: What the hell? Say it again? !
006: Due to your father's wish, we decided to transform you into a normal girl during the next journey.
Many worlds later...
006: I'm sorry, go back, I won't reform you.
