Yukio is about 196 cm. He used to have long hair when he joined the Shinjo Towa Academy, but later changed it to buzz-cut. He has black colored eyes and his jersey number 8.
A friendly individual gets along well with most of his peers. Yukio started playing basketball in high school, and Kojima is his mentor and taught him how to become a good center.
Yukio is a decent center. He has good rebounding skills and can efficiently make mid-range shots. During the first round 'Inter-High District Qualifiers' match against Kuzuryū High, he gave Momoharu and Mokichi some tough time inside the paint and baseline area. He effectively blocked most of Kuzuryū High long passes, and while guarding, Momoharu got injured. His technique is not so great, but he has a lot of power.
