A new idol drama film is now streaming exclusively on Crunchyroll!
Based on the original novel by Kazumi Takayama, “Trapezium” focuses on Yu Azuma, a high school student from Joshu East High School. She dreams of becoming an idol, and she’ll do whatever she can to get there. To reach stardom, she recruits three girls from each of the Joshu prefecture’s high schools to form an idol group:
- Ranko Kashima, a second-year student from Holy Teneritas Southern Girls’ Academy. She is a high-class girl with curly hair and loves Ochofujin (“Madam Butterfly”).
- Kurumi Taiga, a student from West Tech Vocational High School who loves robotics.
- Mika Kamei, a kind-hearted student from Joshu North High School who loves to volunteer.
