Yuna is a beautiful young girl with a friendly, shy and quiet personality. Ik-Han and Shinwoo are childhood friends of her. She's a student of Ye Ran High School and she's in the same class as Shinwoo, Ik-Han and the others. Shinwoo had a crush on her since they were kids. She also becomes friends with Rai and visits him at Frankenstein's home together with Shinwoo and Ik-Han. When she and Rai are introduced to video games, she appears to be quite competent despite it being her first try.
