This display piece aims to evoke the comforting presence she brings to team fights.

Yuumi is a magical cat whose life centers on a living book that acts as both vessel and companion. In Runeterra, she travels far and wide with her book, learning to project her magic through it and to link with allies in order to shield them and heal them in battle. The book stores her memories, spells, and feelings, so when Yuumi attaches to a champion, her power flows through the link, letting her heal, shield, and empower teammates while staying close to her own bond. The character's personality is soft-spoken, curious, and relentlessly loyal, turning even a dangerous skirmish into a moment for comfort. The figure captures this duality: a serene cat perched atop a sentient book, calm and confident, ready to support friends. Yuumi's backstory emphasizes friendship, empathy, and resilience, making her a beloved support whose presence can change the course of a fight.
