The ending of the light novel series is a bittersweet one, leaving many readers with mixed emotions.

The finale of Beyond the Boundary takes place largely within an alternate dimension, a snow-covered pocket world floating above Nagatsuki City, where Mirai has been trapped, battling the legendary youmu Kyōkai no Kanata (the very entity that once slumbered inside Akihito).
In the end, Akihito and Mirai are able to emerge victorious, but not without sacrifices. The ending is a poignant one, with Akihito and Mirai sharing a moment of closure and reflection on their journey. The light novel series concludes on a hopeful note, but one that is tempered by the costs that were incurred during the final battle.
A unique factor influencing the perception of the ending is the history of the light novel itself. Author Nagomu Torii entered the first volume into the Kyoto Animation Award competition in 2011, where it received an honorable mention after the contest ended without a winner. Despite being honored, Torii seemed to lose interest in continuing the series; the third and final volume was released in 2013, the same year as the anime, and notably did not close any major plot threads . This has led to interpretations that the author was not interested in a long-running epic and was content to end the story on his own terms, for better or worse.

Skeptics point out logical holes: "the Mirai that we see is just her last consciousness that can take form because of Kyōkai no Kanata", so once that youmu is defeated, she should not have been able to return. One analysis bluntly calls the finale "an absolute disaster" where "literally nothing is resolved".
In the climax, Akihito’s half-Youmu nature begins to fully awaken, threatening to consume the city. The only way to stop him without killing him is to use the ultimate power of a cursed blood clan member: the ability to create a "Boundary" (Kyōkai) – a dimensional rift that can separate the immortal spirit from its physical manifestation. However, using this power requires a complete, self-annihilating sacrifice of the user’s existence, not just their blood.
Because of this condensed run, the light novels functioned more like a draft or a structural proof-of-concept for the studio. Kyoto Animation took the fundamental core—an immortal half-youmu boy named and a cursed, blood-manipulating Spirit World Warrior named Mirai Kuriyama —and vastly expanded it into their own narrative sandbox.

This ending is a crucial moment of character development for both protagonists. Mirai moves from a suicidal warrior who once attacked Akihito for practice to someone capable of the ultimate act of selflessness. Similarly, Akihito, who had been largely a passive observer in his own life, becomes the active hero who literally wills his love back into existence.
