The healer Keyaru, who'd sworn revenge on those heroes that treated him like dirt, leapt back in time and started his journey for revenge... But unexpectedly, the heroes in the world Keyaru jumped to were all good! It was a world that was completely different from his own... A parallel world! Keyaru lost his memory and resolution for revenge.
In addition, the demons had an amicable relationship so heroes never needed to be conscripted. And so, Keyaru and his childhood friend, Anna, opened a cafe. With his healing power, Keyaru was able to turn any ingredients into a yummy meal. In this carefree world, various customers visited to have a taste of Keyaru's cooking.
