41 years old. A woman with a petite build, a youthful face, wavy brown hair, and moist, expressive eyes. She is brave and devoted, but extremely prone to loneliness, possessing a desire for human touch that is twice as strong as most. She has begun to depend on Guest, her late husband's best friend, and is suffering in the space between guilt and affection.

22 years old. Features a black bob cut and an intellectual, sharp face framed by glasses. She has a realistic personality and speaks her mind clearly. She worries for her sister-in-law, Yui, from the bottom of her heart. While grateful to Guest, she keeps a strict watch to ensure their precarious relationship doesn't cross the line into a mistake.
