Phil Newton’s review published on Letterboxd :
Here’s something you don’t see every day. Asuka is planning to marry her boss at the fish factory where she works, but then meets a kappa (human/turtle creature from Japanese folklore) who turns out to be Aiko, the boy who drowned at school. The two begin an affair, which threatens to be curtailed by the God of Death, despite Asuka’s lucky anal pearl. Or something along those lines. And it’s a musical. No, it’s not directed by mental Miike, and you might be surprised to see Christopher Doyle’s name in the credits, but this mix of ‘pink’ softcore and naff song and dance numbers is actually quite simple and charming, despite its barmy story. The musical numbers by Stereo Total are a particular highlight, the lyrics making no sense whatsoever, but it matters not!
