Beezelbub is 10x Azusa's age but for 1500 years she was a low level bureaucrat. Once she became a minster, she started training, and after a couple hundred years was able to beat up demon nobles, but she hasn't done the daily XP grind like Azusa has, so she's probably lower level.
I think it's more she was trapped by her feelings for the girl, and couldn't move on because the girl wouldn't risk hurting her by giving her a clear rejection. She needed to suffer the pain of rejection so she could be freed of her attachment to the girl.
The group that had translated it pulled their chapters from MangaDex. The new group is going back and doing their own translations of the pulled chapters.
