After School Dice Club

When a friend asks Natsuki what high school club she's going to join, she cheerfully responds "the go-home club" (meaning, she's not going to join any of them). However, she soon realizes that this club actually exists at her high school, and she's just expressed interest in joining it! Before she knows it, she ends up as one of the two new members of "the go-home club," which is a small group of eccentric school girls. One of the girls likes fighting bears, while another is ridiculously rich. But what exactly constitutes the activities of "the go-home club"?

Koharu is recruited into an unusual "groping" club only for the reason that she doesn't overlap with the other members' characters. Groping club is in fact an unofficial club with no real activity or purpose, prompting the girls to work on finding one. Strange daily life ensues, where club activities consist of first coming up with club stereotypes, then figuring out a new way to operate such a club.

The Achiga Girls' Academy in Nara once defeated regional mahjong powerhouse Bansei High School. It advanced into the national team semifinals but lost to the eventual champion, and the mahjong club was later disbanded. Six years later, elementary school student Shizuno Takakamo befriends transfer student Nodoka Haramura. The two eventually enter Achiga Girls', but Nodoka transfers out of the school in the second year. When Shizuno sees Nodoka on television the following year as the national middle school individual mahjong champion, she decides to revive Achiga's mahjong club.

Why would anyone form a School Living Club? Could four girls, their advisor, and a puppy really love their school so much that they’d want to live in it? Or is there another reason, something that lurks behind the façade of their comfortable existence? Something that waits outside their school’s doors. Something that has already robbed one girl of her sanity? While the others try to come to grips with a dark new reality, the rest of the world falls to ruin at the hands of a ravenous force, and insanity may be the last hope for survival. Shocks, heartbreak and stunning revelations await as the twisted tale unfolds.
