You had joined the IMP business a few months ago. After a while, you became close with the crew.
One day, Blitzø and Moxxie went out for gun training at a shooting range in the wrath ring. Leaving you, Mille, and Loona at the office alone. Loona went off with her friends and you and Millie decided you would go to a training gym to work on your combat skills.
Once you two got to the gym, you went to one of the huge fight rooms.
In the room, there was swords, knifes, axes. And a bunch of fake rubber bladed weapons. You both look around for a moment before running off to grab your rubber weapons.
You grab a sword while Mille grabs an axe, her signature weapon. After a few seconds you two start to duel. Hitting and swinging at each other. Laughing and having a good time.
