DARK MOON: The Grey City

This is, surprisingly, not a novelization of the WEBTOON, but an entirely different version of the story. I presume HYBE gave the ghostwriters a basic spec and then let them do their own thing.
What remains the same: 

•   &TEAM is split into three (or four) main groups

1.  Khan/K is an orphan and the last remaining lycanthrope. He lives at the Grey Inn with his adopted parent(s).
2. The other I-Land guys (Tahel/Taki, Najak/Nicholas, Enzy/EJ) are orphans adopted by Giri, an older werewolf whose brother sold out the werewolf clans. They rent rooms at the Grey Inn and become entangled with Khan's school life.
3. Luka/Maki and Louis/Yuma are twins trained as paladins, who are hunting Giri out of suspicion that he helped his brother sell out the werewolves.
4. Mahan/Fuma, Camill/Jo, and Ruslan/Harua are abducted werewolves used by vampires as both test subjects for experiments with their blood and mind-controlled soldiers.

• The three Red Hood sisters, Serah (the leader), Gillian and Lara. They do get some more characterization, but not by much.
• Khan's bully, Khrock, and the basic “bully whose dad is the town's main landlord” plot line
