Accel World - S01

Reverberation A strange avatar has taken control of the Umesato Junior High local network, trapping students and stripping away their clothes and belongings. When Kuroyukihime discovers that other schools are experiencing the same issue, she calls on Haruyuki Arita and the rest of Nega Nebulus-one of the Seven Great Legions-to uncover the truth behind the mystery. Vacation Haruyuki has a physical re-examination in two weeks, and if he doesn’t pass, he’ll be barred from joining Nega Nebulus in future territory battles. Determined to keep their "Silver Crow," Chiyuri Kurashima steps in to help Haruyuki get himself in shape before the test.
