I'm obsessed with meaningful names. Here's a list
Rosalind Dokita is a psychiatrist. Rosalind came from the name Rosalind Franklin, who wasn't credited enough for her works with James Watson. Dokita in African language means doctor
Sonny: Is a seemingly cheerful girl, but has a lot of messed-up sides to her; thus, the bright Sonny girl (not Sunny but she pretends to be one)
William Warren is obsessed with Shakespeare...that's where the name came from. He's known as the William-obsessed William
Atilla Nadha...stick the N from first name to the rest of the surname, and you'll have Anadha. In Telugu, Anadha means Orphan.
Dell Nadha: Atilla's mother. In Persian, Dell means heart
Novan: Wordplay on No One, and also No.1, because she's a genius who eats MATH for breakfast
Mitaki Naya (Naya Mitaki in English way of saying the name) : Naya Mitaki....Nayami Taki...Nayami means worries and troubles and Taki means waterfall...which is where the title of first volume (Show Me: Waterfall comes from). She's the link that connects all characters together, and the main mystery of the series who has the ability to read the deepest parts of a person's feelings, be it sorrow, pain, joy, love and lust; thus, her chapter is titled "The Waterfall That Washed Away All Troubles And Worries"
The main character has no name, but the cast refer to him as Sherlock (his nickname from a long time ago) there are plot reasons for why he has no name
here's the novel if anyone's interested
