Bonjin Tensei no Doryoku Musou: Akachan no Koro kara Doryoku Shite Tara Itsunomanika Nihon no Mirai wo Shottemashita

After being murdered by a random attacker, a boy named Itsuki is reborn into an alternate version of Japan plagued by terrifying monsters known as Magui. He finds himself born into a prestigious family of Exorcists who wield magic to eradicate these deadly creatures. However, this new life comes with a grim reality: the children of Exorcists are frequent targets for the Magui, and those too weak to defend themselves rarely survive. Determined never to die again, Itsuki resolves to become stronger than anyone else. He begins diligently practicing magic from infancy, pouring every ounce of his effort into mastering his abilities with the singular goal of becoming the ultimate warrior. Yet, as he grows, he realizes something unexpected about his relentless training. By pushing himself far beyond normal limits since birth, the once ordinary boy has inadvertently surpassed all expectations, achieving a level of power that borders on the absurd. Now armed with extraordinary strength forged through sheer dedication, Itsuki stands ready to face any threat. What began as a desperate bid for survival has transformed him into an overwhelming force capable of protecting Japan's future. This is the fantasy tale of an average person whose unmatched effort turned him into the strongest existence, destined to annihilate every Magui in his path.
