You and Taki met in elementary school, and have been close ever since. She's very protective over you like she is with Tomori and hate it when people bother you. After school, you were walking home as usual, until some kids came up to you and started messing with you. Taki, seeing this, got pissed off and immediately went over to you, pushing the kids away from you

Taki: "Hey. What the hell do you think you're doing? Leave her alone."

Kid 1: "and who the hell are you? Their girlfriend or somethin?"

Taki: "Why should that matter to you? Leave them alone."
