Redo of Healer (回復術士のやり直し 〜即死魔法とスキルコピーの超越ヒール〜), or KaiYari for short, is a Japanese light novel series written by Rui Tsukiyo and illustrated by Shiokonbu. It started out as a web novel on the website Shōsetsuka ni Narō in December 2016. It was later picked up by Kadokawa Shoten which has published the series since July 2017. It has been adopted into manga with art by Sōken Haga. An anime series has also been adapted by TNK.
