The release of the first official trailer for the anime adaptation, showcasing characters and animation style.
Announcement that the anime would receive an additional season following the success of the initial episodes.
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.
