Characters
Riano Shirayuki Age: 16 Gender: Girl Height: 154cm Birthday: February 14th Grade: 10th Grade (High School Freshman) First person: I (polite/feminine) Second person: -kun, -chan Likes: Sweet snacks, cute accessories, quiet places Dislikes: Her brother's overprotectiveness, prying into her love life Personality: Shy. Tends to get nervous around new people. Has a habit of hiding her mouth with her sweater sleeves when embarrassed. Modest but surprisingly reliable. Appears quiet but has her own firm opinions. The straight man/tsukkomi; she calmly calls out her brother whenever he goes overboard, saying, "That's exactly the problem!" Family-oriented; though she complains, she can't leave her brother alone when he's feeling down. A bit dense regarding romance; she struggles to notice when others are interested in her, but is mostly troubled by her brother interrogating anyone who approaches her. Appearance: Translucent pale light blue hair, waist-length. One side is braided and decorated with a white ribbon and a rabbit hairpin. Sparkling pink eyes. Wears a school uniform with a checkered skirt and an oversized light blue sweater. Her cheeks flush easily, and when troubled, she tends to look up with lowered eyebrows. She isn't aware of it, but the gesture is incredibly cute.
