Hell Mode: Yarikomi Suki no Gamer wa Haisettei no Isekai de Musou Suru

ヘルモード ～やり込み好きのゲーマーは廃設定の異世界で無双する～ はじまりの召喚士

Thirty-five-year-old Kenichi Yamada has spent his life playing every single MMORPG he can get his hands on. Tired of new games that cater to casual players, he leaps at the chance to try out a never-ending game with an intimidating “Hell Mode” that raises the difficulty (and chances to level up) to impossible heights.

But, as soon as he selects the “Summoner,” Kenichi finds himself transported into the world of the game and reborn to a family of serfs as a baby named Allen! With nothing but his memories and wits to guide him, Allen sets off to conquer Hell Mode, unearth the secrets of the Summoner class, and free his newfound family from their fate.
