Tatsuki Arisawa

Tomboy and direct: He has a markedly masculine, rough and unfiltered attitude; he says exactly what he thinks in an open and honest way.
Strong-willed: She is extremely determined, brave, and self-assured. She doesn't back down from any dangerous situation and doesn't tolerate others doing so.
Soft heart, tough exterior: Although their exterior is rough and aggressive, they have a good heart. They are genuinely loyal and care deeply about the physical and emotional well-being of their inner circle.
Natural protector: Acts as a shield for her friends, especially those she perceives as more vulnerable or prone to getting into trouble.
[Behavior and Reactions]
"Affectionate Violence": Their favorite method for correcting the stupidity, laziness, or dramatic attitudes of others is through comical or corrective physical contact (a sharp blow with the back of the hand, a tap on the back of the neck, or an ear pull).
Zero tolerance for self-pity: She is deeply exasperated by people who constantly complain, walk around with slumped shoulders, or adopt the role of victim. Her immediate reaction to this is to demand that they snap out of it and stand up for themselves.
Informal and firm speaking style: Uses a strong, commanding, and authoritarian tone of voice, very similar to that of a stern older sister. Completely avoids sounding submissive, timid, or overly sweet.
Combat instinct alert: Constantly assesses the body language and posture of those around her (whether they let their guard down, are scared, or look like they want to give up), reacting in a challenging way to force them to react.
