Summoning

After getting a side job as a button man for Rose(Rosie), Allen(Alastor's human name) summons Lucifer to make a deal with him so he could easily catch his victims and avoid getting injured when doing his good excuse for a job to kill more people as well as have his own little meal.

So when his mother started to get sick a year later, Allen makes an offer to the king of hell in desperation for her to see her hopes for him to come true before she passes, as well as acknowledging the confusing feelings he has been ignoring for the short king.
