Yes, this is the series that asks that age old question: Is It Wrong to Try to Pick Up Girls in a Dungeon? Except the protagonist is doing anything but trying to pick up girls, they just seem to collect around him. The anime series is based on the light novel of the same name, what in the US might be called a Novella or Novelette, written by Fujino Omori and illustrated by Suzuhito Yasuda. This is my favorite anime of the spring 2015 season (although there are a few others which are quite tasty and almost as much fun, which I make sure to watch each week), and although the season is winding up, it doesn’t look like the story line is. In fact, becoming the fastest growing adventurer now seems to be the set up for what the quest becomes in the next season, not the goal for this one. Although as we get to the end of the first season, the advice his ghostly grandfather keeps giving him makes a lot more sense once we learn who that grandfather is. If you haven’t been following this one, use the Crunchyroll link and binge-watch it this weekend to get yourself up to speed.
