S1·E14 The Boys of the Black Rose

Utena meets Anthy's brother, Akio. Akio has been engaged to Ohtori Kanae whose father is the chairman of the board of trustees of Ohtori Academy. Her father is deceased, so Akio is the acting chairman. Mikage Souji is a twelfth grader who organizes Mikage Seminar, aka the Black Rose Association. He is such a genius that he even writes papers for professors. The building of Mikage's office is called Nemuro Memorial Hall, where it is said that one hundred boys were buried alive long ago. Chida Mamiya has a right to become the Rose Bride. Mikage says he will do whatever it takes to make Mamiya the Rose Bride, and will obtain the Power of Dios and the eternal secret. Mikage says the End of the World admitted Mikage and Mamiya. They say they need a duelist good enough to beat Utena. In the elevator of Nemuro Memorial Hall, Kanae confesses she is suffering. She can't get along with Anthy no matter how hard she tries. Taking advantage of that, Mikage makes her a Black Rose Duelist.
