He appears in the anime during the "Ogre Festival Arc". An athletic-built 2nd-year High Schooler who stands at 2 meters and was originally responsible as Kaori's Guardian who protects her. He's the nephew of Kikyo Katsuragi, thus a cousin of Kaori and Mikan. Due to an incident that happened 3 yrs ago, he left the Katsuragis and only returned during Mikan's homecoming.
