Jun Takahashi is a high school student and friend of Soun Hojo in the Sengoku Collection anime series.
Jun Takahashi's character design in the anime series is credited to Katsunori Shibata. She makes her first appearance in the Sengoku Collection episode Ambitious Princess-I where she is voiced by Kanaka Kondou.
When her friend, Soun Hojo, becomes depressed over the realization that the modern world can't be conquered by one person, Jun suggests that she start attending high school. While there, Jun shows Soun the ropes and the two tussle with school bullies. Upset by the ease of defeating them, Soun gets depressed again which leads Jun to suggest that maybe there is a powerful Shadow Ruffian Alliance operating in the background that Soun should search for.
