Biography
Tio was first seen at the site of Marco's disappearance when Masumi Kotsu, Hokuto Shijima, and Yaiba Todo were searching for clues regarding his attack. He was evasive but polite to the students, telling them that evidence was still being gathered and that they should continue their studies.

Later on, Yuto witnessed Marco dueling against Shun Kurosaki, who defeated him and sealed his soul into a card. Shun mailed it along with Marco's soul to Reiji Akaba.
