Danganronpa Gaiden: Killer Killer (ダンガンロンパ 害伝キラーキラー, Danganronpa Gaiden Kirā Kirā), originally known simply as Killer Killer for its first volume, is a Japanese manga series written by Kazutaka Kodaka and Yōichirō Koizumi and illustrated by Mitomo Sasako. It was published by Kodansha in the magazine Bessatsu Shōnen Magazine from March 8, 2016 to May 9, 2017,^[1][2][3] and collected in three tankōbon volumes. The series focuses on Misaki Asano, a young woman assigned to the Future Foundation's 6th branch, dedicated to murder investigations in the midst of "The Tragedy", as she is teamed up with fellow investigator Takumi Hijirihara, a secret serial killer who only kills other killers, for the honor of Mukuro Ikusaba.

Although a spin-off of the Danganronpa series published to tie in with the Danganronpa 3: The End of Hope's Peak Academy anime series, the series was not initially marketed as such, with its connection to Danganronpa and full title being used as the twist ending of the first volume. The series has received a universally positive critical reception.
