A series of specials included on the Maria-sama ga Miteru 4th DVD releases.

This OVA is a live-action/animation mixed collection of short school ghost stories.

Koni (whose character is based on the famous Sumo-wrestler) and his gang have lots of crazy and incoherent adventures in their town. From fighting with their "Lovely-Teacher" and dealing with Samurai fish, to confirming if "The Armored-Guy's" wife has an affair and saving the world, Koni, High, Moro, Nari and Afro, the Afro-dog, do the craziest and funniest things to have fun.
