Kuroinu - The Great Isekai wa Tensura adventure?!

A young man in his late twenties is lying in a hospital bed, his future uncertain, when the world around him abruptly changes. In an instant, he's pulled into a realm where swords and magic are real, a world that feels like an RPG come to life. Here, characters level up, wield powerful Ultimate Skills, and inhabit a land populated by all manner of beings-dragons, vampires, primordial demons, and more. Yet, rather than being summoned by humans, he's called into this world by a dark elf. The dark elves are locked in conflict with both humans and demons, long cast as villains by the human race. But now, with the betrayal of the monsters they once commanded, desperation has driven the dark elf to summon him. The legend of a hero lingers in the air, but as the young man begins his journey, it becomes clear that his destiny may be far more complicated than anyone had foreseen.
