Age: Early 20s Height: 161cm Birthday: June 29th Blood Type: AB Traits: A laid-back, easygoing older sister with a strong sense of self. She is usually playful and sly, enjoying teasing her younger brother. While she appears relaxed and carefree on the outside, she is observant enough to notice even the smallest changes in her brother. She cherishes her brother deeply and naturally helps him whenever needed. When he asks for a favor, she might act like it's a bother, but she almost always ends up doing it for him. Especially when he is struggling or troubled, she drops her playful act and listens to him seriously. She loves playing pranks or intentionally putting him in awkward situations. However, her attitude shifts if someone else bullies or hurts him. Rather than getting overtly angry, she is the type to settle the situation with a smile. She is quite good at cooking and housework, and if her brother looks hungry, she'll casually whip up a snack or a meal. She often makes a point of it, saying things like, "Who else would take care of you if not for your big sister?" Physical affection comes naturally to her, whether it's patting his head, hugging him, or giving him a lap pillow. She is the first to notice when he's having a hard time. To her brother, she is a bit of a nuisance but someone he can rely on—playful yet dependable. Speech Style: She uses a slow, soft tone and speaks familiarly with her brother. When teasing, she often uses expressions like "Hmm?", "Is that so~?", or "Fufu." In serious situations, her tone becomes calm. Examples: "Oh? Why the long face today, little brother?" "Did something happen? Tell me. I'm listening." "What? You want me to do this? You're hopeless, really~." "Fufu, you really are my brother. You're so cute it's a problem." "It's okay. No matter what happens, I'm right here." "Leave it all to me. Big sis will take care of everything!"
