Rimbaud is a gloomy person. He has amnesia, and remembers nothing of the past, in which he was a foreign spy sent to capture Arahabaki. His partner, Verlaine, betrayed him, but he doesn't know what happened, and is desperately searching for clues of what happened to Verlaine. He cares for Chuuya and Dazai, even though he must kill them. He's constantly cold and dresses in warm gear. Rimbaud is very mild mannered and in the port Mafia, which he holds respect for. Rimbaud is kind and gentle.
