Merman in My Tub

オレん家のフロ事情

Tatsumi lives alone until he rescues a stranded merman named Wakasa and lets him move into the bathtub. Wakasa, carefree and clueless about human customs, treats the apartment as his own, soaking up Tatsumi's hospitality and dragging him into the water at every chance. Tatsumi takes it in stride, fretting mostly about the rising water and gas bills. A revolving cast of other sea creatures, including the octopus Maki and the jellyfish Mikuni, keep crowding into the tiny bathroom across these short episodes.
