Kamisama no Iutoori Ni

Yasuto Akashi skipped school the day the games began, after having a fight with his best friend. While his classmates competed in the games at school, Akashi and other students who skipped school must compete in a separate set of games in order to survive. This series takes place at the same time as part one.
This is the 2nd part of Kami-sama no Iutoori, but no knowledge of reading the 1st part is required.
