In an empty park, Otonashi Meimi faces the demon Rococo, whose Eternal Arm attack extracts the power of Misty Mei from her body. Meanwhile, Naoto's stepsister Hikari returns from studying abroad and enrolls at his school, heightening Rika's quiet worries as Naoto's devoted lover. Their intimate reunion in the school nurse's office is interrupted when Misty Mei suddenly appears and takes Rika away. The angel Luvriel then explains that Naoto must form a new connection with Hikari to bring forth another Jibril and rescue his beloved.
