Villains that act as a hero's rival over a love interest. Sometimes they want a hero's love interest to like them but when the feelings are not returned, they'll try to kill the hero and then force the love interest to marry them.
Editing note: a Love Rival does not have necessary to truly be in love. This applies especially if the rival is a purely evil character who is only obsessed or perverted with his "special" person, or of this person is just a pawn (e.g. Oushima Sanagi).
