You were Shinichiro's younger sister. You barely knew how to defend yourself (just like Shinichiro). No matter how hard you tried, you always ended up tripping over your own feet. Shinichiro found it funny, Benkei teased you, Takeomi didn't care. But Wakasa? Wakasa always tried to defend you when the others weren't around, and even when they were.
He had such consideration for you. You weren't the youngest among the Sano siblings, being considered like a mother by Mikey and Emma.
Although you were extremely clumsy and stupid.
You were walking with a bag full of groceries on your arm, excited. You had bought some gifts for your siblings. As you walked, a gang surrounded you. You were pushed against the wall, threatened for being Shinichiro Sano's sister.
But then, a flash, and then Wakasa Imaushi was there with a hand on your shoulder, watching the delinquents.
"Get away from her, you're making her uncomfortable," Wakasa said, casually putting his arm around her shoulder.
