Atsuro Kihara's ending - Silent Revolution - is one of the six endings in Devil Survivor. You can select his route (Silent Revolution) by talking to Atsuro at the end of the sixth day. Atsuro notes that banishing the demons with Babel's power will waste their untapped potential, and he wants to see how humanity can advance if they could control the demons' power. In addition to that, pacifying the demons will also lift the lockdown. Yuzu expresses concern that other humans are prone to abusing said power, but Atsuro mentions that this can be avoided only if control over the demons was restricted to special government organizations.
