The Demon King's Champion

Once a dedicated hardcore gamer known only as 75, the protagonist pushed his limits one too many times. After enduring countless sleepless nights at his computer, he suffers a fatal heart attack. However, instead of fading into oblivion, he awakens directly inside his favorite video game—thrust into the chaotic middle of an intense boss battle as a fully realized hero. Stripped of proper equipment and lacking the foundational skills needed to survive independently in this dangerous digital world, 75 must rely on his greatest asset: his sharp intellect. Recognizing that brute force will not save him, he cleverly negotiates with Devo, the fearsome Demon King, persuading the powerful ruler to take him under his wing. This unlikely alliance sets the stage for an epic quest, as 75 dedicates himself to ensuring the Demon King maintains his grip on power. To achieve this monumental goal, the newly reborn gamer must rapidly level up, hone his abilities, and systematically conquer every enemy that stands in their path. The stakes have never been higher; failure does not simply mean a "Game Over" screen. If 75 falls short in this perilous new reality, it may very well be the end of his final life.
