Keiki Kiryu is a kind-hearted high school student surrounded by attractive girls. One day, he finds a love letter with no sender information, other than a pair of panties. Keiki begins his investigation by speaking to his senpai, Sayuki.
Because you trashed it, Senpai...
Weil du hier alles zugemüllt hast.
Porque lo llenaste de basura.
Porque você sujou toda a sala.
