Trivia

 * Kirinmaru has a scar from his first confrontation and fight with Towa in Episode 18.
 * Tōga's statement to Zero about her being who she is acts as a callback to what Towa said to Riku in the previous episode.
 * Rin is revealed to be linked to Zero, which could explain Sesshōmaru's inaction when Zero had the forest his daughters were in burned.
 * Setsuna sprouting butterfly wings seems to be a side-effect of the Dream Butterfly's curse.
 * Setsuna vaguely recalls seeing Zero's green eyes before, while she had slept and dreamed a decade before.
 * This is the first time that Tōga, in his humanoid form, makes an appearance other than of the third movie via a flashback. Plus, he is seen to have wielded the mighty demon sword Sō'unga. The only difference is that its immense destructive power was not used to destroy the Grim Comet.
 * This marks Kin'u's first appearance in the present as a teenager, whom Towa naturally mistakes her Gyokuto, as they are identical twins.
 * Moroha uses Heavenly Arrow Barrage for the first time since Episode 16.

Error

 * Tōga cast a complete Meidō Zangetsuha with Tessaiga despite the fact that Tenseiga, which can be seen, was created to contain it and was entrusted to Sesshōmaru to perfect it since it was implied Tōga was unable to master Meidō Zangetsuha.
 * Myōga stated Tessaiga was created as a means to protect Izayoi. The flashback took place 500 years before the series, which would mean it happened 300 years before Inuyasha's birth and that Izayoi was not yet born, so Tessaiga and by extension, Tenseiga should not have existed yet.
