Death Note: Killer Within is a 2024 online multiplayer social deduction game developed by Grounding Inc. and published by Bandai Namco Entertainment. It is based on the 2003 manga series Death Note written by Tsugumi Ohba and illustrated by Takeshi Obata. Players are represented as chess pawns, similar to Near's finger puppets, and divided into two teams—Kira alongside his followers and L with the police investigation team. Both teams must uncover the identities of the opposing players.
