Why is she a Bash Buddy? Because its the only way she knows to survive the bullying she's dealt with ever since her mom [Left/Disappeared/Died]
What does that mean for her Studies? She does her best with her studies, even if she sometimes has trouble focusing. "It's like dad said in his songs, 'Only a fool ass mark ain't learn to count his paper'."
Her social life? She's got a reputation for speaking "thugishly" and her japanese can slip into deep "yankee speak" if she gets angry. Despite these things, she's loyal to a fault and will always be the first to step up for a friend no matter the cost.
What does she enjoy? Why does she enjoy it? Card games, surprisingly. She also has a great love for cute things and Gold. She enjoys Card Games because they were one of the ways she bonded with her first few friends in Japan. Her love of cute things is just natural, and her love for Gold stems from an intense desire for Glory and Fame that she feels her family has lost because of her.
Any hobbies? Embarassing or not? Again, Card Games. She also has a hobby of "conquering" landmarks by taking self-aggrandizing Selfies in front of them. Mildly embarassed by how into the first one she gets, literally no damn shame about the second one.
What's her favorite color and why? She's got two: Red and Gold. In her own words: "Red's the color of ya blood, of the fire spittin' in yo' veins. Gold's the color of a conquerer, of someone who don't take shit from noone and who e'rryone gotta respect."
What's her favorite subject? Is it something she shares easily? Social Studies and Anthropology. She absolutely loves learning about the legends and stories of different civilizations and finding ways to adapt those lessons to her own life comes naturally. It helps that Kotomine-sensei is so easy for her to relate with. She doesn't share her taste for the course easily, but she doesn't hide it either.
Does she like her teachers? Does she dislike them? She likes a few of them, like Kotomine-sensei. The ones that don't treat her like she's stupid just because she's "street" or because she's "just a kid". The ones that do treat her and her fellow students as a burden will often find themselves eternally scorned by her.
