Full Summary

The novel opens with Shiori writing a farewell letter to Takkan before departing for the dragon realm, reflecting on her grief for Raikama and her fear of belonging nowhere. She arrives at the bottom of the Taijin Sea with Seryu, who carries her through a violet beam into Ai'long, the dragons' luminous underwater realm. Shiori carries Raikama's broken dark dragon pearl, which she has sworn to return only to a dragon strong enough to restore it. Jellyfish patrols search her, sensing deception, and Kiki nearly reveals Shiori's plan to keep the pearl rather than surrender it.

At King Nazayun's palace, Shiori is swept into the Dragon King's presence. Nazayun demands the Wraith's pearl, warning that it will soon cleave completely and devastate Kiata. Shiori refuses, citing her vow to return it to the Wraith. Nazayun's daughter, the Lady of the Easterly Seas, extracts strands of her soul, but the pearl protects Shiori. She wakes in a cell where she meets Gen, an enchanter-in-training turned to stone from the neck down. Nazayun announces an immediate binding ceremony, and Seryu forces Shiori to bow, revealing his betrayal. Seryu's mother, Lady Solzaya, will initiate Shiori into rites that will erase her memories and make her a dragon prince's companion forever.

During the binding ceremony, attended by over a hundred dragons, Shiori tries to fake drinking the elixir of forgetting, but Solzaya tips the bowl and Kiki swallows it instead. Lady Nahma exposes Kiki, squeezes the elixir from her, and crumples the paper bird. As Nazayun threatens punishment and brings out the petrified Gen, Elang, the half-dragon Lord of the Westerly Seas, crashes through the ceiling with sea turtles. In the chaos, Shiori dives after Gen, and Seryu creates a whirlpool to carry the boy to safety. Elang attempts the pearl-claiming trial but fails; Shiori snatches the pearl back and throws the starstroke net over Nazayun. Seryu drags her through a whirlpool gate as lightning strikes him.

Shiori and Seryu land in a seagrass field. Shiori insists on rescuing Kiki and Gen. A beaked whale arrives carrying Nahma, who reveals her earlier deception was necessary to maintain Solzaya's trust. She advises taking Shiori to Elang, who can save Gen and knows the Wraith's location. At Yonsar Castle, Elang stabilizes Gen and reveals the Wraith is half demon. Elang agrees to reveal the Wraith's true name and location in exchange for a shard from Solzaya's mirror of truth. They swear an oath on the Oath of Ai'long.

But Elang betrays Shiori to Solzaya. Shiori proposes a wager: find a shard from Solzaya's mirror or give up the pearl. Solzaya demands all seven shards before an hourglass empties. With Kiki's help, Shiori wins. As she swims for freedom, Nazayun captures her, but Seryu arrives in his full dragon form, having come of age. Seryu pins Nazayun, and Shiori pulls the Dragon King's pearl from his heart, forcing him to swear an oath that no dragon will harm Shiori or her kin.

Shiori emerges from the sea and meets Elang, who reveals the Wraith's name: Khramelan, dwelling in Lapzur, a realm of ghosts and demons. She discovers six months have passed. She and Seryu exchange a farewell, and she returns home to Kiata.

Back in Kiata, Shiori learns of a breach in the Holy Mountains that allowed the demon Bandur to escape. At a family dinner, Shiori drinks poisoned wine; Bandur speaks through Qinnia, revealing her blood freed him. Hasho administers an antidote Raikama left behind. Shiori insists on visiting the breach despite Takkan's warnings. Using Raikama's red thread, she and Takkan travel to the Holy Mountains, where they meet Gen, who reveals Bandur's amulet is his weakness. A vision in the Tears of Emuri'en shows Bandur slashing Takkan through the chest.

At her betrothal ceremony, Bandur manifests and threatens the emperor and Takkan. Shiori publicly declares the betrothal over to protect Takkan, then privately binds herself to him with Raikama's red thread. Her father reveals Raikama's past: she was Channari from Tambu, scarred and disguised. Shiori and her brothers travel to the Holy Mountains to retrieve Bandur's amulet. Benkai retrieves it, but Bandur possesses the emperor. Shiori casts the curse turning her brothers into cranes, and they fly toward Tambu.

In Tambu, Shiori learns Raikama's full story: the demon killed her sister Vanna, and the pearl gave Channari Vanna's face. Channari scarred herself deliberately and fled. Shiori buries Raikama's ashes by the sacred tree. They travel to Lapzur, where Bandur captures Shiori and plans to use her soul to sustain his army. Khramelan arrives, battles the demons, and binds Bandur as Lapzur's new guardian. Khramelan flies Shiori, Takkan, and her brothers back to Kiata, where the pearl transforms him into a dragon, fulfilling Raikama's promise. Hasho's right arm remains a cursed black wing.

Back in Kiata, the priestess Janinha curses Kiata to burn. Shiori folds a thousand paper birds to spread her magic. She's ambushed at the Tears of Emuri'en and captured by priests and priestesses. Demons arrive through a breach, and Shiori bargains to go with them. She frees the demons in exchange for their oath not to harm Kiata. Kiki dies, and the breach closes. Shiori, dying, is saved by a divine bargain: the gods agree she'll spend half the year on the moon and half on earth while Takkan lives. Kiki becomes a real bird. The epilogue shows Shiori descending from the moon to reunite with Takkan, who awaits her with a red lantern tied to his blue one.
