Asuna returns to the surface

Asuna Watase’s return to the surface closes her journey through Agartha with a physical crossing and an unfinished farewell. At the edge of the Interstitial Sea, she leaves Ryuuji Morisaki and Shin beside the pool of Vita-aqua and jumps into it, emerging back in the surface world. The return reunites her with the life she left behind, but it does not restore the companions to their former homes or settle the questions that brought them together.

The parting at the Interstitial Sea

By the spring of Vita-aqua, Asuna, Morisaki, and Shin are together again at the edge of the Interstitial Sea. Shin asks Morisaki what he intends to do next, addressing him as an Arch Angel. Morisaki refuses the title: he has betrayed the Arch Angels and believes there is no place for him on the surface. His response makes clear that returning upward is not a shared option. He has chosen to remain in Agartha, where he still hopes to find another way to bring Lisa back to life.

Morisaki’s determination leaves Asuna and Shin silent. He appears willing to pay whatever price another attempt at resurrection might demand; the scene also leaves open whether his resolve is an effort to challenge the human curse and blessing Shin had spoken of. The return therefore takes place alongside, rather than after, Morisaki’s continuing pursuit. Asuna can leave Agartha, but she cannot persuade him to abandon the purpose that has kept him there.

Shin, too, cannot simply go back to where he came from. He tells Asuna that returning to the village of Canaan could sour relations with Amaurot. Asuna begins to suggest another possibility, then stops: the surface atmosphere is poisonous to Agarthans, so she cannot invite him to accompany her. His choice is to travel with Morisaki instead. Although he does not know whether resurrecting the dead is right, he hopes the journey may bring him closer to an answer. The two companions thus set out together, not because their convictions are settled, but because both remain caught in questions that the return cannot resolve.

The crossing and its cost

With the pool of Vita-aqua before her, Asuna struggles to find a suitable farewell. The available words—good-bye, take care, farewell—do not seem to fit what she wants to say. She chooses a promise oriented toward the future: “Let’s see each other again.” Shin smiles and answers that he will see her again. Their exchange gives the separation a different shape from a final leave-taking, without promising when or how a reunion might happen.

Morisaki urges Shin onward, and Asuna watches them leave. Only then does she jump into the pool of Vita-aqua and return to the surface. The sequence gives the departure a clear cost: the route back is available to Asuna, but the conditions that shape Morisaki’s and Shin’s lives keep them below. Her return is consequently not a simple restoration of what she had before. It ends her time in Agartha while leaving her connected to the people and unresolved choices she has left there.

Return to surface life

The narrative moves forward by half a year after Asuna’s return. On the morning of her graduation ceremony, she is still in Mizonofuchi, where the railway crossing and its trains offer a sign of gradual change in the town. More trains now run than before, and the crossing, once open most of the time, is often closed at that hour. If services continue to become frequent, Mizonofuchi may become less isolated, making it possible for residents to commute to work or school; Asuna herself might attend a high school outside the town.

These changes place her return within ordinary time and a changing local landscape, rather than presenting it as a complete resolution. As a train passes, Asuna looks back in the direction it came from and up toward Mount Obuchi. She realizes that she has not visited her familiar spot there in quite some time. The movement of the train prompts a glance away from the crossing and toward a place associated with her own past, linking the surface life she has resumed to a memory she has not entirely left behind.

The blue light on Mount Obuchi

On the outcrop of Mount Obuchi, Asuna thinks she glimpses a blue light. The sight is uncertain, and the narrative does not identify its source. Asuna wonders whether it could be what she suspects, then makes up her mind to climb the mountain after the graduation ceremony, for the first time in a long while. The scene ends before she reaches the spot or confirms what she saw.

That unresolved glimpse gives the return an open ending. Asuna has crossed back into the surface world, but the blue light turns her attention toward a place she intends to revisit and a possibility she cannot yet confirm. Her promise to meet Shin again likewise remains in the future. The event closes her passage out of Agartha without closing every connection to it: the return is a completed crossing, while reunion, recognition, and whatever waits on Mount Obuchi remain beyond the scene.
