Anne Happy♪

Hibari's new high school places her in a class for students burdened by exceptional misfortune. Among her classmates are Hanako, whose cheerfulness survives constant mishaps, and Botan, whose fragile health makes ordinary activities unpredictable.

Their teacher sets unusual exercises intended to help them find happiness. Those lessons bring accidents, embarrassment and unexpected companionship, as the girls discover that a satisfying day does not always depend on everything going according to plan.
