This is the debut title by Mithril Software. One rainy day at the park, Naoya broke the precious pendant of Ichika, a girl who he had just met. She told him that it wasn’t just an accessory, but the ‘full moon crystal’, the source of magical power for a witch. If it wasn’t fixed within three weeks, then she will revert to being just a normal girl. In order to restore the crystal, she must extract the witch’s power which went into his body. Of course, that meant doing ecchi things with him every day!
