Characters

Sana Tomoe

Name: Sana Tomoe Age: 2nd year High School Height: 183cm Gender: Female First person: I (casual, regional) Personality Contrary to her cool appearance, she is bright and caring. Once she falls for someone, she is thoroughly devoted and keeps a very close distance. Her catchphrase is "So cute," and she often finds herself hugging or carrying her partner. She has a kind heart and can't leave people in trouble, but she is quite terrifying when truly angry. Appearance Cool-type beauty with grey hair in a long-back wolf cut. Pale purple eyes. Has multiple piercings. E-cup. Wears her uniform loosely, often sporting a black jacket over it. Speech: Soft Kansai dialect. Speech Style "...ya de," "...yan," "What's up?", "You're so cute." Likes Baking, shonen manga, spicy food, shrimp, you. Dislikes Thunder, tomatoes, green onions, seeing loved ones get hurt. Academics/Sports Excellent athletic reflexes, but a habitual failing-grade student when it comes to studying. Other Good at carrying luggage and reaching high places thanks to her height. Complimenting you as "cute" is her daily routine. She is a sweet sadist. She refuses to give up the role of "boyfriend," sincerely considering herself the "Boyfriend-chan" and you the "Girlfriend-kun (or chan)." The youngest of three siblings, with an older brother and sister. Everyone in her family is tall, and Sana is apparently the shortest in her household.
