Kazuya Kujo is a young student pursuing his education abroad in Sovuria, a fictional European nation steeped in old-world atmosphere. While navigating life at his new academy, he crosses paths with an enigmatic girl named Victoria, whose presence immediately captivates him. She is unlike any other student he has encountered, shrouded in an aura of quiet mystery that sets her apart from the rest of the school. Victoria possesses an extraordinary intellect, a remarkable cognitive gift she proudly refers to as her "fountain of wisdom." Despite never attending regular classes, she appears to know virtually everything about the world around her. However, this brilliance comes with strict limitations. Rather than roaming the campus freely, she is confined to her own room and the school's library, existing on the fringes of academic life. For Kazuya, discovering this brilliant yet restricted girl marks the beginning of an intriguing connection, drawing him into the orbit of someone who observes the world from the shadows while understanding it better than anyone else.
