Yuto

Yuto is a Regular recruited by FUG. She is part of Team FUG formed for Jyu Viole Grace to participate in the Workshop Battle.

[Spoiler] 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. [/Spoiler]
