During the first attack on the Mud Whale by the Allied Empire, Suou attempts to stop the battle by speaking to them, but stops his attempt once he sees Ouni kill some of the invading soldiers. After the funeral of those murdered in the first attack, Suou is officially appointed mayor of the Mud Whale, and is told of the Council of Elders' plans to sink the ship. Horrified, he tries to stop them, but is knocked out and imprisoned beneath the ship. After the Council of Elders' plans fail, Hakuji releases him.
He then announces to the citizens of the Mud Whale that they will fight back against the invading forces. During the invasion, he at first hides inside the towers like the other Unmarked, but later grabs a sword and heads out to fight. When he sees Hakuji fall, he rushes over to him to hear his dying words, but they are interrupted by Liontari, who kills Hakuji. Suou attempts to fight Liontari, but is easily beaten. But before Liontari can kill him, Suou is saved by Shuan.
During the fight between Liontari and Shuan, Suou finds and injured child and holds her. Then, due to the Nous, Suou sees Liontari's past. Suou then grabs Liontari's leg, and tells him that he can stay on the Mud Whale. Before he can answer, Liontari is attacked by Shuan, who tells Suou that the inhabitants of the Mud Whale will never live with someone who killed so many of their own. Right before Shuan is about to finish Liontari off, Suou stops him, and tells him to focus more on protecting the inhabitants of the Mud Whale.
