Yusei is Yukari's little brother. She also supports him as a sister, though not as much as she supports her boyfriend.
Tsutomu is Yukari's former crush.
When the Mizusawa team won the second place at the Tokyo tournament and got to the national championship at Omi Jingu for their second year, Yukari made them t-shirts. But, at the top-right there are words 'for the second place' which make Misuzawa choose to wear their original t-shirt instead.
Her relationship with Hiro Kinashi from Hokuo seriously disturbs her brother.
- In the Volume 6 omake, Yukari asked Tsutomu to take off his eyeglasses and show her his eyes. After seeing his eyes, she dumps him. In the anime summary episodes, however, she only had a crush on Desktomu, and replaced him with Retro-kun as soon as she met him.
