Gleipnir

The Gleipnir watch order is as simple as it gets: a single 12-episode season with no movies, OVAs or specials attached. Start with Episodes 1-12, which cover the entire anime adaptation from Shuichi and Claire's first transformation onward. Because there's only one season, the correct order is just Episode 1 through 12 in sequence — nothing to slot in and nothing to skip. If you're wondering where to start, this is it, and the series runs straight through without any side content to worry about. There's no need to hunt for a special or prequel before beginning, since the anime is self-contained in these twelve episodes. Fans hoping for more will need the manga to continue past the anime, but for the animated run this twelve-episode season is the complete watch order from beginning to end.
