OK. I really didn't want to resort to this action. But desperate times calls for desperate measures and since you have not respond back yet, you leave me with no other choice but to do this. (BIG INHALE)
          
          SPOILER ALERT! ROSIE IS THE ONE WHO OWNS ALASTOR'S SOUL!!!
          WHEN ALASTOR WAS STILL A LIVING HUMAN, HE USED A RITUAL TO SUMMON ROSIE AND MADE A DEAL WITH HER SO THAT HE CAN BECOME THE MOST POWERFUL SINNER IN HELL!!! BUT ROSIE GAVE HIM A TASK AND AS LONG AS HE HASN'T COMPLETE THAT TASK, HIS SOUL BELONGS TO HER!!! 
          
          What that task is I have no clue, we'll just have to wait until Hazbin Hotel Season 3 to reveal it.

Don't know of your coming back, but here's an idea for tadc
          Zooble- Ilia, both are prickly and Ilia disguised herself as a human to join the academy in Altas so I like to think she may have developed some form of dysphoria from that
          Gangle- Velvet, both are timid and seem to suffer self doubt 
          Jax- Mercury, both are assholes with short tempers and some trust issues
          Pomni- Ruby, the main characters who have a rough start and become friends with just about everyone and acts as a sort of leader to the main cast
          Kinger- Ozpin, odd men who are at the center of the problems of their respective shows. Acting as mentors/father figures to the cast
          Ragatha- Pyrrha, both are people pleaser with self doubt holding them back from what they want.
          Caine and bubble- themselves
