Yuu Naruse

Yuu Naruse was the one and only friend who stood by Tomoko Kuroki throughout their middle school years. Upon entering high school, she underwent a striking transformation—trading her once understated look for a fashionable, eye-catching style that quickly earned her widespread popularity. Yet beneath her glamorous new appearance, her bond with Tomoko remained completely unchanged. Her genuine warmth and remarkable patience toward Tomoko's quirks make her one of the rare few in the series who truly watches over Tomoko from the heart.
