Love Advice from the Great Duke of Hell is a webcomic about a socially awkward college student named Paul who summons a powerful demon noble, Duke Asmodeus of Hell, expecting a grand love potion or magical romance. Instead, the veteran Duke provides brutally blunt and absurdly literal advice on relationships, hygiene, and self-improvement, dragging Paul through chaotic and often humiliating situations to help him win over the girl he likes. Readers enjoy it for its sharp humor, the hilarious contrast between the demon's hellish perspective and mundane human life, and the surprisingly heartwarming character growth, as the cold-blooded duke becomes an oddly effective mentor.
