- Description from Novelupdates

The strongest Hero in history, Nakamoto Keisuke.

He was summoned to another world in the spring at the age of fifteen years old, and when he successfully defeated The Demon King, he was already thirty-two years old. He had finished his role in another world and returned to Japan, but the reality that had been waiting for him was, “Middle school graduate with seventeen years of blank period” label. He couldn’t find a decent job and had no choice but to spend his days working part-time.

Before such a Nakamoto, a beautiful girl who self-proclaimed had come to return the favor, appeared. “I’m the reward for Hero who had defeated Demon King”, said Angelica, a girl who came from another world that persistently tempted Nakamoto to make her his wife. Together with a high school girl who looks like Elsa, his beloved girl that he lost in another world, Nakamoto with his cheats skills got caught in a harem life.

It all started with a Book review…[To Kill A Demon Lord…] had everything; It had Magic, It had action, it had an abundance of interesting characters and—probably most important of all—it had Vampires.Kevin (Username: Kevin_The_Man) enjoyed the read. Stayed up to date with every chapter update and it quickly became his favorite Webnovel… That was until the Author killed off his favorite character, Caius Von Helsing, A Vampire Spawn who spent most of the story frustratingly resisting his Vampirism so as not to ‘become a Monster’.Kevin quickly wrote a review expressing his dissatisfaction so naturally, when the Author replied and asked for Kevin’s help in making a revised edition of the story, he quickly accepted…… Only to fall asleep and wake up in the world of [To Kill A Demon Lord…] as none other than his favorite character, Caius Von Helsing, the Vampire Spawn.Kevin—now Caius—quickly discovers that there is so much more involved in making a ‘revised edition’ of a novel than simply writing it. And that there are powerful forces that especially want Caius to die and stay dead…… But that death is still quite in the future so Kevin—now Caius—is quickly optimistic.He has a mission now;To enjoy the wonders this world has to offer—as the original character never would—by fully accepting and evolving his nature as a Vampire.
