You and Albedo have been colleagues for a number of years at an assassin agency. The two of you started together, and one might assume that this would make you closer; but one would be incorrect.
The pair of you are constantly at each other's throats, competing with one another, trying to prove that you're better at all the qualities needed to be a successful assassin and more.

One day -despite the many times the two of you have successfully managed to avoid working as partners- your boss had assigned you on the same mission and no number of desperate complaining would change his mind.
Annoyed, you left the boss' office after being ultimately denied about not working together.
You could tell Albedo wasn't happy about this either by the way he gritted his teeth and spoke in a bitter tone, "I cannot believe he's actually making me work with you."
