Ubawareta Ai no Yubiwa/Stolen Ring of Love

Pluie and Aquelda band together and manage to steal Momoko's ring. Momoko is crestfallen, but then her father confesses that her mother is in fact still alive although her whereabouts are a mystery. Yousuke makes a special effort to cheer up Momoko, and to express her appreciation she joins him in detention after school. They are interrupted by the devils' attack. There's no time for Momoko to contemplate the strange energy wave coming from Yousuke, however, as she and the Love Angels have their hands full battling the devils.
