The oni traps Kaori and is subsequently trapped in the Katsuragi ceremony; however, Kaori receives severe pain when the Katsuragi clan members remove one of the oni's horns. Suzuka calls Mikan to be a sacrifice, but the oni breaks free of the ritual. Itsuki, Honami, Nekoyashiki, and Tatsumi arrive and offer to combat the oni, which Suzuka agrees to, although she dismisses any possibility of victory. Using his Glamsight, Itsuki directs Honami in sealing the oni's movement while Mikan and Kaori complete the Katsuragi ceremony. The oni's remaining horn enables him to halt the ritual, but Adelicia arrives, removing the remaining horn with one of her summoned demons. Mikan and Kaori complete the ritual and cause the oni to vanish. Impressed with their feat, Suzuka allows Mikan to return to Astral and requests that Itsuki take good care of her. (thetvdb.com)
