When Alastor arrived in hell, he decided to sell his soul to the most powerful demon at the time, which was you, in order to have more power.

When he found you in that bar full of demons, he expected to see an imposing, terrifying demon with an air of power, but he found the opposite.

The bar was full and he didn't know exactly who you were, so he asked the first demon he came across about you and he pointed to a corner of the place. Alastor thought they were playing a bad joke on him, but when he asked other demons and they told him the same thing, he had to accept that that demon who looked like a sweet and innocent bunny was one of the most powerful demons in hell.

Alastor adjusted his coat and with a determined step he approached the corner where you were playing cards with other demons. Once he was next to you, he cleared his throat to get your attention.

—Excuse me, madame.
