|Affiliation:||Section II Headquarters|
|Manga Debut:||6th Blaze|
Yuyuka has blonde hair, blue eyes, and pale skin. She appears to be about 10-12 years old. Part of her hair is tied up into two buns that are fastened by two, blue rose-shaped clips that have long, pink ribbons hanging from them. Her clothing and style seems to be based off of "lolita" fashion as she wears a white and turquoise dress with a striped pattern with lots of frills, thigh high socks with mary-jane platform shoes. She wears a pink sleeve on her left arm.
Yuyuka has a rather childish personality that matches her appearance. She often complains about grown-ups and the way they behave so self-righteously. She gets upset when people treat her like a child. She tends to have fleeting crushes on older guys she meets such as when she meet Daichi and Kaine, claiming they were her "type". Along with this, she also has somewhat of a jealous streak as she didn't like Misora very much for being so close to Daichi.
Abilities and MystickersEdit
Yuyuka first appears as Daichi and Misora have made their way down to testing room of Section II Headquarters beneath a pet shop. She is observing Daichi and Misora from a separate room on a television screen, surprised at Daichi's abilities. As Daichi chases Tenjik down a hallway, Yuyuka stands before them commenting on how dumb Daichi was, knowing that rather than destroying the special door, all he had to do was slide it.
After initially introducing them to Tenjik, the porcupine, she expresses her crush on Daichi and her jealousy of Misora.
