I have never read a Revenge story manga before but i did thoroughly enjoy this one. If you have a twisted since of justice or kinda sadist nature you will empathize with the MC and hope he accomplishes his goals. At first i was kinda confused since the story said healers cant use any combat abilities so i was a little annoyed when he has a heal ability that can damage/kill people. But his healing ability is kinda special than others so hes exempt from other healers norms. So i kinda let go that he could do damage as a healer since hes special.The art style i did enjoy. i loved all the sadist grins and laughs. And i can really feel the pain and emotions from reading and looking at the scenes.
