Ep. 15: Itsuki, Helena, dan Isshiki menjalani kehidupan sebagai siswa sementara Makoto mengingat saat ia melindungi Boneka Lumpur

Three young children, Itsuki, Helena, and Isshiki, live there as students; Isshiki finds a Golem living in the ruins beneath the mansion and wants to protect it. (Source: HIDIVE) A flashback occurs to when Makoto, Itsuki, and Helena were being raised at the Bähbem manor. Makoto finds a Mud Doll underground and decides to take it back to its mother and father, though Itsuki has his doubts and Helena is against the matter. Armed forces are later summoned to assassinate the Mud Doll, but Makoto creates a sound barrier to shield the firing of the rifles. The Mud Doll slowly deteriorates when it reaches outside the manor, saddening Makoto. In the present, Makoto looks back on that day, wondering if he would have the chance of meeting his parents someday. (Source: Wikipedia)
