A sweet, mature, big sister-like voice
Yuuri is usually calm and mature, gives off a relaxed air, and is formal in her actions. She also is quite serious at times, but she always cares for her comrades as she looks after Yuki in the school, being fully understanding and accepting of her delusions. She manages food, electricity, lessons, and other resources and activities, showing that she is responsible. As the big-sister figure, Yuuri seems intelligent and knowledgeable, and occasionally helps Yuki with her studies. She tends to keep a strong front for the other members.
