Death March kara Hajimaru Isekai Kyusoukyoku (WN)

Suzuki, an adult programmer, suddenly notices that he’s been thrown into a different world while wearing casual clothes at level 1. He gained high levels and treasures after using the 3 times use-disposable-magic, Meteor Shower, at once. After that, he intends to do different world “sightseeing tours”? He meets 3 beast girls, beautiful purple and black-haired sisters, and an eccentric blonde-haired elf girl along with various people during his trip. Although there are occasional fighting with demons and demon lords, this is a heartwarming fantasy story at heart.
