Setsuna Seiei

Setsuna is the main protagonist of Mobile Suit Gundam 00. Setsuna was a child soldier who was brainwashed to murder his own parents, and was later cast aside when he was no longer useful. He grows up hating war, and decided he must do what he can to prevent it, even if it means more violence. He regards Gundams as the means to finally end conflict, and sees himself as one. Even so, Setsuna is kind and respectful towards people. He just prefers to be alone as he focuses too much on his mission.
