A sea otter therapist who is secretly an alien stranded on Earth listening to fish problems every episode sounds absurd until you realize the show is actually about loneliness disguised as comedy. The alien doesn't want to be found. The creatures coming to talk to him don't know what he is. Everyone in this show is hiding something, and somehow that makes it gentle instead of sad. This one slipped past everyone. It shouldn't have.

Japan is home to just three sea otters, and one of them is not a sea otter at all. He is an alien who got stranded on Earth and took on an otter's form to stay hidden. All sorts of sea creatures come every day to seek advice from this highly intelligent otter-like visitor. The result is a comedy with a science fiction twist, built around the odd consultations of a disguised extraterrestrial.
