When Keyaru obtained his abilities as a Hero who specialized in curing all injuries irrespective of seriousness, it appeared he would walk the road to a fantastic future.
However, what awaited him rather was great misery; he had been exposed to years of apparently endless hellish abuse and torture.
Keyaru’s healing abilities enabled him to collect the memories and skills of those he handled, slowly making him more powerful than anybody else.
However, by the time he attained his entire potential, it had been much too late–he’d lost everything.
Determined to put his life back on course, Keyaru chose to unleash a powerful healing spell which rewound the whole world back into the time until he started to endure his dreadful fate.
Equipped with all the anguish of the past, he attempts to redo everything so as to meet a new function –to exact revenge upon those who’ve wronged him.
