Yuto

Yuto (유토) is a Regular recruited by FUG. Not much is known about Yuto, apart from the fact that her mission was to gain the Elders of FUG's trust and to switch places with Hwa Ryun.

Appearance & Personality
She always wears a deep hood, so little has been seen of her true appearance. Underneath it is a red mask, which allows for free movement while concealing her features.

Yuto may in fact be someone related to Hwa Ryun, or possibly from same clan.

Thorn
While confronting Reflejo, Hwa Ryun revealed that she was not the Yuto that he knew. Yuto was actually sent to gain the trust of the Elders and then switch places with Hwa Ryun.

Abilities & Powers
She is a skilled warrior, being swift enough to fight Vespa one-on-one with her double edged blade. She also uses a pair of floating devices as footholds, allowing her to manoeuvre and dodge in midair.

Note: this was Hwa Ryun fighting but it is likely that she was fighting the same way Yuto does normally considering she was undercover as Yuto and they might have been found out the secret if she had a fighting style that differed from Yuto's.

Notes & Trivia

 * Her clothing and weapon make her look very similar to Darth Maul from Star Wars.
 * There were some initial controversies regarding Yuto's gender. It was confirmed by Reflejo that Yuto is indeed female.
 * According to SIU's blog, the real Yuto is a character that will appear later in the story.
