The eve of the operation to retake Tokyo coincides with the school festival, and Aine is nowhere to be found!  Amaterasu is supposed to be giving a big concert performance at the climax of the festival, so Kizuna sets off in search of her.  Can he find her and bring her back in time, or will Sylvia have to go instead?
