Stoic and mature, Yuumiko proudly presents herself and walks more elegantly than more properly sized Tokotas. Others often look down upon her, as she commonly appears as a lazy girl who makes her packmates do all the work. That's not it at all, but Yuumi can't be bothered to correct onlookers. The title "boss" or "big sister" is a lot more suitable a title. She keeps stern and commanding even in the most dire of situations, though since her accident with a rabid bear, she keeps to the sidelines. She remains calm and refined even outside the field, watching from afar as her packmates play and frolic. Yuumi's had a crush on her handler ever since she laid eyes on him, and strives hard to keep females and a certain male handler away from her master.
