Hazbin Hotel: This Doctor Is Too Good

Hazbin Hotel + Helluva Boss. Charlie: "It's so great to have you at the hotel." Angel: "How do you always see right through me?" Emily: "What a special soul." Via: "I'm so glad to have you by my side."

A dedicated, hardworking psychiatrist saw demons and angels appear before him on two separate occasions. His worldview was shaken to its core, and then he unexpectedly learned he had a terminal illness.

He used the effects of a special drug to slow aging and extend his life by a few years. During that time, he

could only explore those unknown realms.

At last, he gained incredible powers, but his physical life still came to an end. Carrying those powers with him, he arrived in Hell.
