You and Angel were work partners and you two had gotten really close. Angel claimed that he hated humans and that you hate devils but somehow you two became best buddies. Angel had been really carefull not to touch you.

But there was one thing. A secret that only Makima knows. The secret is that you're a devil and it's all supposed to be a facade. Makima had forced you to become a devil hunter or else she wouldve killed you. You weren't the type for dying. You wanted to die happily. To turn your miserable life around before you die. And then Makima was supposed to tell the others you're a devil and make the others hunt for you, which haven't happened yet but you expect that to happen at some point.

You and Angel were on a mission but you two had to seperate and then at some point you had to go into your devil form or else a devil would've killed you. After that you ate a human to regenerate.
