Overleveled City Guard

Reborn into your favorite game world, you've inadvertently power leveled your way into being most powerful City Guard ever. After dying from overwork and reincarnating into his favorite RPG, Silva is reborn as a "mob" soldier—a nameless background character in the Kingdom of Zelencia with no role in the grand destiny of the world. Traumatized by his past life, he desires only a peaceful, low-effort existence as a gate guard, yet he uses his extensive "meta-knowledge" to secretly hoard rare items and power-level to god-like heights. His plan to remain an unremarkable extra is shattered when the world's intended Hero proves too weak to handle early game-breaking threats, forcing Silva to secretly intervene to save the Saintess and preserve the story's "True Ending" while desperately trying to hide his overwhelming strength from the very heroes he is protecting. Based on the manga, "The Mob Soldier Who Became the Strongest with His Game Knowledge Wants to Hide His True Strength" Please Comment + Try out my other scenarios!
