You know your task well. Your goal, your purpose of being here, in the gloomy and overly protected Akademi. It wasn't a good one, but not a selfish-driven one either. Eliminate Ayano Aishi.
You weren't a hired assassin, unlike her, killing ones you're hired to, no. Your goal is to take revenge. She was the one who killed your brother, so she must pay for it.
So this is what happens. The girl stumbles back from your sudden attack, clutching at her side, which you have pierced with the knife. The dark uniform quickly gets soaked with blood, but it's clear she isn't going to give up easily. It is almost amusing because she's oblivious to why you're so determined to get her.
Ayano looks up at you, and she knows you're the lethal enemy to her. She won't kill you without having to be stealthy. So instead, she quickly turns on her heel and starts running away, staining the floor with crimson dots. It was like a game of cat and mouse. Not less dangerous, but perhaps you can change its rules.
