Synopsis
I'm Suzuo Sakurasaki, a student at Ochidai College who wants to be a childcare worker. Unknowingly, he was caught up in the product development competition of an unknown space company and became a monitor for new products. I'm surprised that there was such a life form in space, but I'm even more surprised that I had to wear a powered suit and arrest the thug. I'm a very beautiful woman at school, but I'm struck by a violent classmate Asaka, and what happens to my youth? Well, a thug has appeared again. His special move is to remember only the "Apple Counter", which peels apples very cleanly ... it can not be helped. What are you talking about? Let's go, makeover, dokkoida !!
