Puzzle : Bokura no 48 Jikan Sensou

About

An armed group has taken over a class of top-achieving students at a super-famous prep school! To save the teacher who has been taken hostage, the students must find 2,000 pieces scattered throughout the vast school building and complete the "puzzle"! Some students panic and refuse to participate, and others run away. The time limit is fast approaching. Furthermore, an unexpected "picture" emerges from the pieces that are collected little by little!
