The Milk of Repentance, the Wine of Sin

Angel Dust is the most popular porn star and prostitute in Hell. Kumakko, an internet starlet, falls in love with him, but he refuses her feelings. After the rejection, she resorts to having a strictly transactional relationship with him. Angel Dust’s boyfriend, Valentino, sees the relationship developing, and seeks to ruin them both through corruption, manipulation, and wreaking devastation upon anything that comes between him and Angel Dust.

Fan-game of the Amazon Prime adult cartoon series, Hazbin Hotel. In no way canonical to the main series, with the protagonist being an original character.
