Game Chishiki de Saikyou ni Natta Mob Heishi wa, Shin no Jitsuryoku wo Kakushitai

Silva suddenly awakens to a startling reality: he has been reincarnated as a nameless background soldier in the very video game he was obsessed with during his past life. Armed with an intimate understanding of the game's mechanics and lore, he does everything in his power to survive the perils of this dangerous new world. Yet, determined to keep the original storyline intact, he deliberately conceals his overwhelming abilities, choosing instead to remain an unremarkable mob character in the shadows. His careful plans unravel when an unforeseen crisis forces him into action against a fearsome demon—a monster so powerful that even the prophesied hero struggles to withstand it. Without meaning to, Silva effortlessly defeats the beast, but his victory comes at a steep cost: the entire spectacle unfolds directly in front of his absolute favorite heroine from the game. As whispers of his hidden might begin to spread across the land, the quiet life he envisioned slips away. Now, the strongest soldier in the realm must step forward, unleashing his true power to protect the character he cherishes most in this thrilling heroic fantasy.
