Merman in My Tub

オレん家のフロ事情

High schooler Tatsumi finds an injured merman named Wakasa by the river and, without much thought, brings him home and lets him move into his apartment's bathtub. Wakasa turns out to be vain, dramatic, and utterly unbothered about overstaying his welcome, and soon draws a rotating cast of anthropomorphic sea creatures, including an octopus and a jellyfish, into Tatsumi's cramped Tokyo apartment. Each short chapter plays their mismatched cohabitation for gentle, slice-of-life comedy.
