Full Moon - A La Recherche De La Pleine Lune s01e49
Titre original : Mitsuki's Feelings - Meroko's Feelings
Izumi tells Mitsuki and Meroko about a way to prevent Takuto from becoming a ghost. There is a mystic lily known as the Flower of Forgetfulness. If he were to touch it on his lips, not only would Takuto lose his memories from when he was a human, but he will also forget about being a Shinigami. Most of all, he will forget Mitsuki and Meroko.
