Ep. 4: Amou and Gashin defeat the Ghost AMAIM while Risa dies and Amou leaves Yatagarasu
Amou and Gashin return to their camp to find it under attack by an unknown AMAIM nicknamed the Ghost. They collaborate to critically damage the enemy, forcing it to retreat. During the battle, Risa, a Yatagarasu member Amou had grown close to, is killed while attempting to distract the Ghost. Amou suffers trauma upon learning of her death as Yatagarasu evacuates the area. North American military officers arrive to investigate and determine that Kenbu and Jogan fought the Ghost. Intrigued by the Ghost's presence, these officers decide to deploy additional forces. Gashin leaves Amou to grieve. Amou ultimately decides not to join Yatagarasu due to fear of losing friends. Gashin permits Amou to leave with Gai, provided he hides Kenbu for later recovery. Amou conceals Kenbu behind a waterfall and departs.
