One day, one of his Instructors recommended him for position in a company called Global Exos, who made an announcement of making history with the newest technological invention.

Arakawa Kouki is reincarnated to a Japan with a different history than the Japan he knows with the memories of his previous life still intact. Kouki was discouraged, “Aren’t reincarnation stories supposed to be at some fantasy world filled with swords, magic and elves?!”
