Yousuke Aramaki

Aramaki's missing sibling; an important leader among the refugees, as hinted at in the first season. In episode 23, he shares a cup of tea with Kuze, asking him what he intends to do with the refugees. They had apparently seen each other before overseas in the streets of Taiwan (episode 16). He appears last in episode 26, helping the refugees evacuate to the Dejima bridge via small boats.
