Ok so Lum is a super hot alien with blue hair and pronouns who comes to earth and falls in love with a stupid failboy. She has fangs and is obsessive about her Darling and loves him uncondotionally. She's also a genius but also a bit stupid. She's so yandere but like it's cool because Ataru deep down loves her too he's just a cringe lil failboy who doesn't like to admit it.
