Orenchi no Furo Jijo

A reserved teenage boy named Tatsumi shares a small Tokyo apartment with Wakasa, a self-centered and mischievous merman who has taken up residence in the bathtub. Adjusting to life with an unexpected aquatic roommate proves challenging, especially with frequent unannounced visits from Wakasa’s ocean-dwelling companions, including an anthropomorphic octopus, jellyfish, and hermit crab. As they navigate daily life together, the two must find ways to manage their differences and the increasing chaos in their shared living space.
