Yuu Ishigami

石上優

Yuu Ishigami, the treasurer of the Shuchiin Academy student council, is a reserved individual who manages the school's funds and is highly regarded by Miyuki. He harbors a deep fear of Kaguya and often keeps to himself, struggling with a depressed outlook and an inferiority complex. Despite his challenges, he is compassionate and willing to help others, even at the expense of his pride. His character evolves as he develops feelings for Tsubame, leading to an unintentional confession that ultimately results in heartbreak when she gently rejects him at graduation.
