InuYasha the Movie 3: Swords of an Honorable Ruler
Sunrise
InuYasha the Movie 3: Swords of an Honorable Ruler centers on Sō'unga — the third great sword of the dog demon clan, alongside InuYasha's Tessaiga and Sesshomaru's Tenseiga — which is revived from an ancient seal and begins seeking a new wielder. Sō'unga is a sword with a sinister will of its own, capable of opening a portal to the underworld and commanding an army of the undead. The film provides the deepest exploration of the InuYasha brothers' shared history, revealing the full context of their father's legacy and the sword he left for each of them. A brief vision of Inu no Taisho (the Great Dog Demon father) carries significant emotional weight.
Swords of an Honorable Ruler is the most lore-rich of the InuYasha theatrical films, diving into the relationship between InuYasha and Sesshomaru through the lens of their father's intentions. For fans fascinated by the siblings' complicated dynamic, this film provides the most extended engagement with that theme in the franchise. The action is well-choreographed, with both brothers wielding their respective blades against a shared threat, and Sō'unga as a villain-sword concept provides novelty in a franchise already rich with legendary weapons. Non-canonical but essential for InuYasha fans interested in the brothers' backstory.
