Todo Arata, a corporate drone salaryman, died due to a mistake from god. He was reincarnated in another world as an apology, and received the special perks 'a strong body that won't get sick or hurt', and 'the ability to copy skills and magic just by seeing them'.
And so, the place where Arata was reincarnated turned out to be a place where races known as the strongest, that appeared in legends and myths, lived. Races like divine beasts, high elves, demon gods, ancient dragons, true ancestral vampires, and more.
This would normally be a dangerous place, but the body given to Arata by god was stronger than even the strongest races, meaning this danger was of no concern to him.
A giant boar was downed in one punch, and turned into a tasty prey, and an ancient dragon's breath felt pleasant. There was nothing that could hurt that invincible body.
And so, Arata, along with the girl and the so-called strongest species he met on the island, eats tasty food, makes a lot of ruckus, and relaxes while enjoying this second chance at life given to him by god.
