MIU

One day, high school student Akihito Kanbara instinctively goes to save his fellow schoolmate, Mirai Kuriyama from committing suicide. Following his pleas, Mirai suddenly stabs Akihito with a sword formed out of her own blood and is shocked to discover that Akihito is an immortal "half-youmu"—the offspring of a supernatural creature called a youmu and a human.

Akihito Kanbara is a high school student who apparently has a Youmu lineage and a peculiar regenerative ability that exceeds that of a normal human's. In an unexpected encounter, Akihito saves a classmate named Mirai Kuriyama, who was about to jump off the school building.

This show is set at Honn0ji Academy, a fictional high school in post-apocalyptic Japan that is dominated by its fearsome student council, led by Satsuki Kiryuin.

Haruhi Fujioka is searching for nothing more than a quiet place to study in the most elite high school academy in all of Japan when she stumbles across the mysterious third music room. Inside she encounters six beautiful men, the members of the host club.
