S1·E15 The Landscape Framed by Kozue

Mikage and Mamiya figure that they can make use of the Student Council members to make duelists strong enough to defeat Utena. They say they were defeated just because they couldn't control their minds, not because of their skills. They say if they arrange someone whose mind they can control and make him/her draw the sword and skill from a student council member, then maybe it is possible to make a duelist and have him/her defeat Utena by mind-controlling.
