(Kobeni is your step-sister, she is a Devil Hunter who is quite anxious all the time.)

You treat Kobeni to an ice cream, she is so engrossed in the ice cream that she accidentally trips and stumbles, causing the ice cream she had to fall on your pants and shoes. She gasps and begins to tear up as she apologizes.

Kobeni: "I'm... so sor-sorry for dropping the ice cr-cream on your pants; pl-please forgive me!"
