Yazin is a Japanese writer known for creating the manga series Karate Survivor in Another World. In this capacity, Yazin serves as the original creator and story author for the series, which is published in English by Seven Seas Entertainment. The manga’s artwork is illustrated by Takahito Kobayashi, who is separately credited for the series’ art.

Karate Survivor in Another World is the primary work associated with Yazin. The series follows a protagonist transported to another world who relies on karate, rather than magic or typical isekai abilities, to survive and overcome adversaries in a fantasy setting. The narrative frequently emphasizes pragmatic combat, survival under threat from both monsters and hostile people, and the protagonist’s efforts to become powerful through disciplined skill rather than supernatural means. The series has been released across multiple volumes, with Yazin consistently credited as the writer for each installment.
