Aizen route summary

The route follows after Twilight Faction common route (Book 1), which I assume you would have already known/read. The MC will just be called MC instead of Futaba (default name) to make it simpler.

To recap, the common route ends with the Senkitai attacking some sort of government meeting, with the Onikiri and our protags fighting them off. The Senkitai knock MC unconscious, and then take off. Aizen tries to shoot them down, but they got away.

The ayakashi are concerned and immediately wants to take off after the Senkitai. Aizen tells them not to be rash, because there’s too many unknown factors. He wanted to withdraw and reorganize a new plan. Toto and Gaku especially are not having it, and says that it might be too late for MC if they have to go back and redraw the plans. So they all ignore Aizen’s words and go after the Senkitai. Ouji hangs back for a little while to use his smoke to subdue the feral ayakashi and then run after the others.

Aizen gives the order to Ichijou to take the ayakashi bundled in Ouji’s smoke to the labs. Ichijou is shocked but obey. Side note: In the Night faction common route, Aizen claims that normally the Onikiri will just release the ayakashi they find back to the wild. I’m not sure if this scene shows that this is not normal, hence why Ichijou is shocked, or if this is a retcon because of the writers being disorganized. This is never ever addressed or explained in the route, so I mention this now because it’s not like I’m spoiling anything.

Aizen sends his dove shikigami out “after them”. 

The scene then cuts to Kagemaru. Aizen’s gunshots had nicked Zantetsu in the shoulder. Because it’s the anti-ayakashi ironsand bullet, his powers are drained and he can’t use his whirlwind anymore. He and Kagemaru are forced to walk.
