Synopsis
Reverberation An unknown avatar seizes control of the Umesato Junior High Local Network, confining students and stripping them of their clothes and belongings. Upon discovering that other schools face the same issue, Kuroyukihime calls together Haruyuki Arita and the remaining members of Nega Nebulus—one of the Seven Great Legions—to uncover the truth. Vacation Haruyuki has a mandatory physical re-examination in two weeks. If he fails, he will be barred from participating in any further territory battles with Nega Nebulus. To prevent their legion from losing their "Silver Crow," Chiyuri Kurashima decides on her own to help Haruyuki get into shape before his exam.
