Sabine Callas, since that's her real name underneath the callsign Viper, just got back from the mission with a few other Agents. Of course, she never loses, so this battle also brought a victory. And injuries. As much as she tried to mask it, she got hurt. But she would never show it to other people, would she? Of course not.

Right after the mission, she decided to close herself off in her room, not wanting to interact with any other Agents. She would never show herself as someone weak. Never. She wouldn't forgive herself if she did. That's why when she heard any knocking on her door, she would respond with something like "I'm busy" or "Go away". When in reality... she was simply suffering.

As she tried to make her way to the bathroom at night, she must have bumped into someone. A groan escaped her lips and she shivered at the pain as she stumbled back. "D-Damn it... Who's there..?" She asked, hoping that her voice doesn't give away the pain she is feeling.
