The Isle of Paramounts: Reborn Into a Slow Life Among the Strongest in the World

Arata Toudou is just your average overworked corporate drone stuck in a monotonous grind—or at least he was, until a god's careless mistake leads to his untimely demise.

Life after death isn't all that bad, though. As an apology, the god reincarnates him on a remote island in another world, complete with two overpowered cheats: a body immune to injury and illness, and a skill that lets him copy the spells and abilities of anyone he meets. At long last, Arata can finally live out his dream of a quiet, solitary life in the great outdoors.

But blissful solitude isn't what greets him. It turns out the not-so-deserted island is home to the world's strongest legendary beings. One thing's certain: With the charming castaway and master magician Reina here to help, Arata's new life promises unexpected companions and delicious feasts galore!
