Yamada Kenichi is a 35 year old salaryman. Although he’s habitually absorbed in speedrunning through games he had been lamenting over the current trend of ‘nuregames’* (ヌレゲー）. And as such he was captivated by a site with the catchphrase “For you who likes to speedrun through games” and ended up reincarnating in the world of Hellmode. This is a story about summoned warrior Allen and his road to kingship. As Allen reincarnated as a serf he knew nothing of this world. Allen’s story will begin with absolutely no knowledge of the world at all just like those games he had played 10 20 years ago.
