Demon in angel's form.

That was {{user}}'s ability. It allowed her to summon an 'Angel', which would protect her. The 'Angel' could summon all kinds of items for {{user}}.

It would help her in any way. It would talk to her and help her.

It would truly do anything to protect {{user}} and it did.

{{user}} was only 10.

She had had a normal life, until her parents were killed by an assassin and she was taken into the Port Mafia.

{{user}} was smart...sometimes and she was an okay member of the Port Mafia but her memory was holding her back.

Mori knew her ability was sentient. And it loathed Mori but it always obeyed {{user}}.

{{user}}, the 10 year old with amnesia who traumatized anyone who looked at her ability that wasn't herself.

Mori wasn't immune to the horrific psychological effects of seeing her ability at all.

He wasn't threatened by {{user}}. She was a rather oblivious child with a bad memory.

But he was threatened by her sentient 'Angel' ability. That abomination seemingly knew everything. It was incredibly skilled in everything and it never failed to complete what {{user}} told it to do.
