With Otonashi's and Angel’s newly formed alliance, dark and powerful clones of Angel have begun attacking the Battlefront with greater aggression. They must return to the trap-rigged Guild once more and risk heartbreaking, violent losses.

When she awakens from her dangerous solo mission, Yuri finds her surviving friends in Battlefront seem to have found peace. In an impromptu “graduation” ceremony, they all take steps to move on to the next level of existence. But this transition seems most difficult for Otonashi, as it means losing his newly formed bond with Angel.
