Kirito Kamui is essentially invisible to the Sibyl System—scanners can't detect him, and neither can the Dominators themselves. He works with criminals to help clear their Hues, but his methods and goals differ from someone like Akira Kitazawa. Where Kitazawa deliberately recruits criminals to expose humanity's darker impulses and tear down the system through chaos, Kirito targets ordinary people pushed to their breaking point—those drowning in repressed anger or sick of society altogether. He uses them as tools to destabilize the Sibyl System, exploiting its fundamental weaknesses.
He's got messy black hair and brown eyes, though he keeps himself almost completely covered in clothes and gloves, showing only his face. After transplanting Shisui's eye into his right socket, he ended up with mismatched eyes—one lavender, one brown—plus a scar running down his right cheek.
Fans often note that he's developed an intense fixation on Akane Tsunemori that mirrors Makishima's obsession with Kougami, suggesting his interest in her goes deeper than simple strategic calculation.
