Senkou no Night Raid

Synopsis

Sakurai reports to Aoi and Kazura that Isao might be involved with the Pan-Asianism movement. It is not soon after until Isao kidnaps Aoi and lets him listen to the Asian delegates' meeting at a tea parlor. Isao voices out his own ideals on Pan-Asianism, later encouraging Aoi to join in his group. Meanwhile, Kazura, Yukina, and Natsume mysteriously find a map toward the tea parlor placed by Kuse. Once outside the parlor, Kuse does his best to prevent them from interrupting.
