Nobody talks about this one. A fashion model married to a literal stag beetle produces a daughter who exists purely to destroy the peace of mind of everyone around her, and the show treats this setup with complete deadpan commitment. Tsumami doesn't learn lessons or grow. She just wakes up every day and finds new ways to obliterate normalcy, and that commitment to pure chaos comedy, with zero redemption arc in sight, is exactly what makes it work.
Tsumami's parents are about as mismatched as it gets: a fashion model and a big, human-sized anthropomorphic stag beetle who fell in love and married. Their only child is a half-human, half-stag-beetle girl with jaws sprouting from the top of her head and a serious fondness for watermelon. She is also a relentless troublemaker who turns other people's lives upside down and enjoys stirring up calamities in public. The comedy runs across 84 online episodes, drawing its laughs from the odd family and the trouble their daughter leaves behind.
