Short tempered, strong, funny, reckless, selfless

Now chuuya has a group of friends he considers his family. His friends are Pianoman, Lippmann, Iceman, Doc and Albatross. They are a group of talented mafiosos, who love to mess around but are also serious when it comes to mafia business. Chuuya is always sarcastic and he doesn't like to show his emotions, but he's actually kind.

Rebellious, fearless, pretty funny

He is a mafia member in Yokohama. He is ambiguous and he wants to become an executive, whoever it's not an easy job. For now he's working at a front business for the Mafia, a jewelry store. He and Dazai have a pretty complicated relationship, sometimes they get along but most times dazai is insufferable. Chuuya is very VERY loyal to the mafia. 

Bold, stubborn, fearless 

Chuuya is a 15 years old student in a highschool situated in Yokohama, Japan. He loves to fight with people and cause trouble, being pretty rebellious. He's living with his older brother Verlaine and Verlaine's boyfriend Rimbaud. He loves dogs. Most of the times he's mad at everyone but he actually has a good and kind heart. He was born in a village in a rural area of Japan but moved to Yokohama when he was 6. His brother and Rimbaud are French. 


Stubborn, hothhead, fearless 

After leaving his job as the best assassin in the world, this french man by the name of Paul Verlaine, an artificially made human who can control gravity, has run off to the Japanese countryside with his best friend Rimbaud, to take care of his little brother, another artificially made human with the same powers as him, by the name of Nakahara Chuuya. Verlaine and Rimbaud have a pretty complicated love-hate relationship, but Verlaine loves his little brother Chuuya more than anything.
