Nagamasa Midori is a talented survival gamer who shares a long and arduous history with Matsuoka and Yukimura. Tachibana, set against him in the first round of the TGC, charges into the battle with all her might--both to get revenge for what happened to Matsuoka and the others in the past, and also to get the chance to admit that she is a girl... But which team will win this game in the end when neither can afford to lose?!
