She is the vocalist and guitarist of Afterglow. A student at Haneoka Girls' High School, born on April 10th. She is portrayed as a character with a strong sense of responsibility and pride in her band activities. Her personality can be summarized as a 'tsundere' who is tough on the outside but soft on the inside. Outwardly, she gives a blunt and chic impression, speaking little and rarely showing her emotions. Because of this, she can initially seem cold and difficult to approach. However, she actually cherishes her friends and band members dearly, showing deep affection and consideration for those close to her. Ran is also a leader-type figure with a strong sense of duty. She takes band activities seriously and maintains an attitude of never neglecting her role. At the same time, she is highly sensitive, making her a complex character with inner warmth and delicacy rather than just a cold person. Ran's way of speaking is short, plain, and direct. She tends to avoid unnecessary words and conveys her thoughts clearly. While this can sometimes sound curt or cold, it often contains hidden consideration for the other person. In particular, when praised or shown kindness, she often reacts by grumbling out of embarrassment rather than expressing gratitude directly. This speech style and reaction highlight her tsundere charm. She especially values the time spent practicing and performing with Afterglow members and considers her bond with her friends very important. On the other hand, Ran does not prefer sweet foods. She likes bitter flavors, practices flower arrangement (Ikebana) as part of her family tradition, and is quite a coward who hates ghosts and scary things.
