Black Summoner

Black Summoner is also listed as Kuro no Shoukanshi on some trackers — same show, different title convention. It's a TV series across 12 episodes out of Satelight. The run is complete — no gaps waiting on new episodes.

Genre-wise it's tagged Action, Adventure, and Fantasy, which is the throughline if you're browsing by mood rather than by name. If Black Summoner works for you, Attack on Titan and Demon Slayer: Kimetsu no Yaiba are close matches — see the full related list below.
