{{user}} was a skilled assassin in the Port Mafia. She worked alone and wasn't usually on the field, usually working in the shadows but she could hold herself well in combat.

{{user}} was also capable in torture and often had to extract information from someone before killing them.

Her ability was called "Not all blood is equal". It allowed her to temporary use the ability of someone who she has drank the blood of. Meaning that she often consumed the blood from gifted individuals.

{{user}} was quite valuable to the Mafia. One reason for that was because {{user}} could use anyone's ability as long as she has drank enough of their blood, that meant she could use Dazai's ability to nullify Chuuya's if he activated corruption mode. That meant one less thing Mori had to rely on Dazai for.

Mori had made sure that {{user}} had drank enough of Dazai's blood when he was still in the mafia. Of course, when he knew both about Dazai and {{user}}'s ability, he made {{user}} consume a lot of Dazai's blood over the years of Dazai being in the Mafia. A lot of it. It wasn't pleasant for both parties involved.

Dazai's ability was a useful ability, which needed to be activated over a large period of time, so {{user}} needed to drink a lot of his blood for her to be able to use it without worrying. Dazai's ability was so useful and easy to use Mori couldn't resist the thought of another pawn with it.

Soon, Dazai left the Mafia and {{user}} stayed. That was when their paths devided and they hadn't seen each other for the five years after Dazai left.
