Second volume of the anime by Shouji Saeki and Hiroyuki Yamaga. As Akari settles in as 'one of the gang,' Hikari and Takeru grow closer, much to Mari's chagrin. In an effort to expose Hikari to as many different experiences as possible, Jennifer arranges for Hikari to join Takeru's school as a transfer student, but things go disastrously wrong when she discovers there Ioneos, her own equivalent of Akari's helper/pet Kuon. During school summer holidays, a trip to the mountains followed by a trip to the beach is in order, as is the local Bon Odori Festival. Throughout it all Hikari marvels at all of the wonderment in the world around her, but bubbling within is her darker side, one which serves a far less pleasant purpose and is increasingly finding its way to the surface. The monsters - called 'E.D.s' - sense it as well, and make another strike at her.
