The 73rd Cabinet Arc

The 73rd Cabinet Arc started off when Hyacen was finally able to attend school. He was assigned to a room where a cabinet that has not been open for 200 years reside. The cabinet is a memory box that contains the memories of his father, Nori, Kashin and surprisingly his mother, Seneka.

The arc mainly revolved around Hyacen's struggles to be part of the new environment he now lives in and his strong urge to unlock the mysteries of the cabinet.
