After an unfortunate accident involving lightning, fifteen-year-old Mochizuki Tōya dies—but when he wakes up, he is sitting face-to-face with God. “Regrettable to say this, but I made a slight mistake…” moaned the old man. But it’s not all lost! God offers Tōya a chance to be reborn in another world—a world of swords and magic—and, as an apology, God allows him to take a smartphone with him.
And so Tōya’s adventures begin in his new, outdated pseudo-medieval world! He sets out on an exciting, carefree journey, visiting all kinds of places. Along the way he meets many different people, gaining important companions. And before Tōya even realizes it, he discovers the secret of this world: he has been given a legacy from an ancient civilization!
Friends! Joy! Sadness! Amazing machines! An exciting story of swords, magic, and smartphone mobile apps begins!
