Gachitora! ~Hooligan Teacher in High School~ lives up to its name. The main character, Torao Kaji, is a thug turned teacher.
Besides chasing down a photographer who is stalking a student, Kaji also takes a schoolgirl to a love hotel, films that student in hopes of helping her overcome her shyness and uploads the footage to the internet. He also tries to take a student's mother to a love hotel.
Doesn't sound like there's much studying going on in this game - in the classroom, that is.
Oh, and there's a side-scrolling shoot'em up arcade-style mini-game, too. Players need to get a high school to help another student.
Gachitora! ~Hooligan Teacher in High School~ is out in Japan on April 21 on the PSP.
