Mirai Mizue's debut animation short film.

Debutante Detective Corps begins with introductions to the five main characters, Miyuki, Reika, Youko, Nina, and Kimiko. It seems these five girls are incredibly rich and have been sent a threatening video tape by forces unknown. A police guard is set up at the school where the girls have enrolled. Kimiko, however, doesn't like the idea of being cooped up at school, and convinces the rest of the girls to trick the police into leaving. No sooner are the police gone, however, then the girls are assaulted by three armed terrorists. What ensues is a rather silly escapade with our heroines attempting to thwart their attackers.

It can be rough transferring to a new school—even more so if you don't want to make any friends, like Nobuaki Kanazawa. But the reason for his antisocial behavior soon becomes clear when his class receives a text from someone called "The King." Included are instructions for the "King's Game," and all class members must participate. Those who refuse to play, quit halfway, or don't follow an order in the allotted time of 24 hours will receive a deadly punishment.

Having played the game before and watched as those around him died, Nobuaki tries to warn his clueless classmates. Unfortunately, they only believe him after the King's Game claims its first casualties. Stuck in a horrific situation with no chance of escape, Nobuaki has a choice: put his own survival above those around him, or do what he couldn't before and save his classmates.
