What happens when an intruder from the sea stakes claim to your bathtub? A cool yet demure teenage boy named Tatsumi must learn to live with the self-obsessed and playful merman, Wakasa, in a small Tokyo apartment. These two dissimilar young men will learn what it takes to deal with one another in their everyday lives. Who knows, maybe something beyond friendship will unfold between them? Stranger things have happened. Or have they?
Mellow and responsible Tatsumi has gotten pretty used to his new roommate–the energetic and needy merman, Wakasu–who has taken what seems like permanent refuge in his bathtub. While regular visits from Wakasu's undersea friends and Tatsmi's affectionate little sister have become commonplace, the bathtub suddenly seems a little less safe when a sharp appears. Is their hungry new acquaintance friend or foe? Whether it's testing new bubble bath, hosting a butler cafe, or training for the Olympics, it's never a dull day in Tatsumi's bathroom.
