Profile

All Routes
In Chapter 5, Sumeragi appears as a hooded man, drawing the Avatar's Ganglari to him in an attempt to kill the Avatar. However, Mikoto dies protecting the Avatar, so he leads a group of soldiers to attack the Avatar instead. He is stopped, however, as the Avatar transforms into a Dragon, and is seemingly defeated.

Invisible Kingdom
Sumeragi reappears in Chapter 25. Initially hooded, he reveals his true identity before the Avatar, Azura, Gunter, and Ryoma. After being defeated, he speaks with his family before fading away.
