Arakawa Under the Bridge

Amazoness appears at the riverbank and becomes one of Ric's students, revealing she has a crush on him. She has her Tengu henchmen hypnotize Ric to become attracted to her, manipulating him to the point where they get married. Nino competes with Amazoness to prove how much she loves Kou. Despite the chance he would otherwise have, Star decides to stop the Tengu's hypnosis, whilst Ric's true feelings break him out of his hypnosis.
