藤間 結羽

Likes: Cameras
Dislikes: Lewd things

Yuu is a childhood friend of Shintarou who is two years younger than him. She lives right next to him and is close to him almost like a family member.
She is good at housework, takes good care of Shintarou, and has a friendly personality. She feels sorry for her hero's environment, living alone from an early age, and takes care of him like an older sister type. Although Yuu is usually caring and friendly, when Shintarou teases her, she allows herself to get more rough with him, using a bit of force.
