Saki remembers the first time she met Kuro’s cousin, Sakuragawa Rikka. Saki had heard that Rikka had passed, and tries to get more information out of Kotoko. Meanwhile, the forums on the wiki site become rather active again, making Steel Lady Nanase’s presence even stronger...

Just as it looked like the site readers accepted Kotoko’s solution, it ends up getting shot down. However, Kotoko had another solution ready. In order to defeat Steel Lady Nanase, she unleashes a second and third solution, but Sakuragawa Rikka and Steel Lady Nanase continue to get in her way. Will they be able to vanquish the ghost?
