The Principal is happy. A wealthy man is considering placing his son, Kazumi, in Shuriken School, along with a huge cheque, which would put an end to the school's financial dilemma. But first, the boy will spend a day at the School, to see if he likes it. Kazumi seems to appreciate Eizan, so the Principal puts him in charge of looking after the boy. But Kazumi is so spoiled rotten, that soon everyone avoids them (even Eizan's friends avoid him). The teachers themselves threaten to resign. Eizan feels miserable. When the Katana kids jump in and kidnap the boy, Eizan is faced with a choice. What if they just keep him? Well...perhaps not.
