Season 1 was one of my favorite anime binges in a long time. Such a fun mix of thoughtfulness (movement through time), silliness, and cool scenes (The Ruins of The King's Tomb). I can't wait to watch season 2. I know it's airing as I write this, but I like taking in entire seasons at once if I can manage it.
