This game was released with the third DVD and Blu-ray Disc volume for the Grisaia no Rakuen anime. This side story is a character-driven visual novel featuring some of the same characters. This time, it's Michiru who takes the lead role in this slapstick comedy. She tries to decide on a new club activity with the help of Sachi and her other friends, but it's harder than it sounds...
