Strike to Heaven

What would you do if you reincarnated into the universe of War of Atlantis, the mobile game you once dominated? To the rest of mortals, this post-apocalyptic world is a mad land where modern-era technological remnants coexist with the terrifying Singularities and monstrosities of the Kyōkai. A world where 60% of the planet is held by non-human beings, and where only superpowers can live without fearing becoming dinner for monsters and demons. But to Futsu Emma, it is a familiar game. Thanks to his absolute knowledge of the mechanics, the resources of his peculiar martial family, and an implacable System that gives nothing away, Emma managed to ascend to the highest power ranks in the world before the main story even began. He is already a force of nature capable of challenging catastrophic-level entities with his bare fists. He possesses an overwhelming advantage, power, and a growing—though involuntary—harem... but this reality is not a turn-based game. Here, death is permanent. "Bosses" have no health bars to show how close they are to dying without first giving them the beating of their lives, and the fabric of space-time has already begun to crack, dropping strange visitors beneath the silver moon. Emma is already strong, but to survive what is coming, he will have to become even stronger... and create the strongest student guild in the world!
