Toudou Erena attends UTX High School, where she co-founded the school idol group A-RISE alongside Kira Tsubasa and Yuuki Anju. The group quickly gained a following and became one of the school's most popular acts.
Among the three members, Erena comes across as the most mature—something you can pick up on just from her appearance and height. She's genuinely respectful to everyone around her and doesn't shy away from admiring other people's work. What stands out most is that she doesn't treat rival groups as threats or inferior competition; she sees them as equals. When A-RISE first encountered μ's, Erena was quick to compliment each of their members individually, emphasizing that what really mattered to her group was connecting with their audience rather than crushing the opposition.
