Kaifuku Jutsushi no Yarinaoshi #18

Kaifuku Jutsushi no Yarinaoshi, also known as Redo of Healer, is a dark fantasy light novel series written by Tsukiyo Rui and illustrated by Shiokonbu. Originally serialized on the user-generated novel publishing website Shōsetsuka ni Narō starting in 2016, the series was later acquired by Kadokawa Shoten for print publication. The narrative follows a healer who, after being exploited and abused, chooses to rewind time to exact vengeance upon those who wronged him.

The physical light novel volumes, including issue number 18, serve as the primary media for the story, featuring detailed character illustrations that lean into the series' mature themes. The work became a subject of significant public discourse upon its adaptation into an anime, with critics and audiences often debating the boundaries of its graphic content and its subversion of traditional isekai tropes. The print volumes remain a staple of the Kadokawa Sneaker Bunko imprint.
