Summary
The Half-Demon Princesses decide to ask next morning for the Sacred Tree of Ages to open its gateway to the feudal era, so they can help their fathers, in case Osamu targets them. Sōta tells Towa that he will always think of her as his biological daughter, and that the decade they had together was the joyous years of his and Moe's lives. Towa assures a weeping Mei that she will remember her always. Moe tells Setsuna to keep it up with the violin, which the half-demon girl promises. Akuru then appears to open the portal on the Sacred Tree's trunk, albeit with some difficulty, but sadly fades away from entering his time-based powers. Mei assures Towa that she will no longer cry, and that the half-demon girl does not need to worry about her anymore. As the portal closes, Moe assures her husband that they will someday see them again, which Sōta agrees. Back in the feudal era, the Half-Demon Princesses are shocked at just how massive and imtinidating the Grim Comet become. Towa wonders exactly what her homeroom teacher is after, as Inuyasha and Kagome arrive to inform their daughter and twin half-nieces that demons has been being absorbed into the true form of the Grim Comet: the Grim Butterfly! Osamu senses the presence of Riku, his "younger brother" as both are Kirinmaru's incarnations, and prepares to achieve his ultimate goal. As Riku holds off demons, Rion approaches her father who is asleep after fighting Osamu. Seeing this as an opportunity, Rion holds the Kyūyōkon apple to surpress Kirinmaru's immense demonic powers, but is approached by Osamu. He expresses his happiness at finally meeting her, reminding her that he is the right arm that Tōga of the West had cut off six centuries ago. He assures Rion that he will help her construct a peaceful world, in which she no longer have to suffer. Conflicted, Rion allows Osamu to fly off with her, and they become linked with the Grim Butterfly via, a feat that will ensure Osamu's immortality. He offers Riku the same, but he declines as it is not what he desires to achieve, even for Towa's sake. Having regained conscious, Kirinmaru witnesses Rion being absorbed into the Grim Butterfly and flies to tear it open in a desperate attempt to reach his beloved daughter. Kohaku arrives to give Towa a genuine Kikujūmonji, which can repel evil spirits, and leaves with his nephew Hisui. Within the Sacred Tree of Ages, Sesshōmaru finally awakens and exits the Tree with Rion, only to encounter Kirinmaru who desires to finally settle their duel. Sesshōmaru tells his wife to watch him as he fights, and that she tells her mighty demon husband that she will not back away.

Trivia

 * Akuru sacrifices himself by using his very last ounce of his powers to open a portal for the half-demon princesses to return to the feudal era, meaning he dies in this episode which marks his last physical appearance.
