Monogatari Series: First Season

Main character finds himself constantly in situations in which he sets on saving someone from supernatural danger, using supernatural means himself. Most of the characters in need of saving are girls and so a group of female admirers slowly builds around the protagonist. The novel still stays story oriented and doesn't get distracted by harem aspects much. Most of the story is happening within one city.
