Death March vol 1
Suzuki Ichiro, a programmer, suddenly wakes up in an alternate world after dozing off working overtime. Although he starts at Level 1, he quickly obtains a high level and inexhaustible treasures after using his new player reward magic, Meteor Shower. Then he decides to go "sightseeing" in the parallel universe?
He meets three beast girls, beautiful purple- and black-haired sisters, and an eccentric blond-haired elf girl, as well as many other interesting people along the way. Although he occasionally is forced to fight terrifying demons and demon kings, this is a heartwarming fantasy story in essence.
