Story plot:
Wataru is an average, boy living under a very rich family. One day, he decides that he wants to go to the abandoned workshop on the other side of town.
Walking there, late at night, he spots a gang of thugs pestering an Ethiopian ( black african) girl. In an attempt to save her, he stupidly (very stupidly) tries to fight them off but gets badly hurt. Just as the bullies were about to finish him off, the girl beats them all up as if they were rag dolls. Wataru blushes with rage as he sees her super human strength. Thanking Wataru, the girl agrees to be his maid, and the story continues!
