Whether she's confronting the players taking advantage of the Nerve Auction or facing a creepy masked girl in a haunted school-- she's not backing down. With the help of new allies and with club mates Asagi and Sugiura by her side, Mai jumps straight into the next event. Can they unravel the riddle behind a massive, unbeatable knight?!
