In Another World With My Smartphone

Fifteen-year-old Touya Mochizuki dies after an accidental lightning strike caused by God's mistake. To make amends, God offers to reincarnate him in a fantasy world and even lets him take his smartphone along. Touya awakens in a pseudo-medieval setting filled with swords and magic, but with a modern device still at his disposal. Rather than following a single fixed quest, he travels from place to place, meeting new people and pursuing whatever goals capture his interest.
