14 years after the Shaman Fight, Asakura Hana is attacked by Yohane and Luca who want to kill Hana and take his place as the true heirs of the Asakura Family.

After running across Tamamura Tamao, Asakura Hana hides that he was fighting again and rushes back to Funbari Onsen. Tamao decides to take Umemiya Ryunosuke's motorcycle so that she can investigate the secret Asakura Family. Back at the inn, Hana is caught by the Hana-Gumi Waitresses. By the time Hana returns with the first aid kit to the cemetery, Yohane is gone.

After waking up in the hospital, Asakura Hana believes the previous night's events to have been a dream and intults Alumi Numbirch's appearance. Overhearing this, she punishes him and then chews out Umemiya Ryunosuke, Tokageroh, and Amidamaru.

Despite being sworn enemies, Hana takes it upon herself to mentor Haba, a newcomer to the world of education, on the intricacies of being a transfer student. She also warns Haba about her behavior, which mirrors that of a rebellious second-year junior high school student. Surprisingly, Haba discovers that Hana, despite her yearning for friendship, is also friendless. In a bold declaration, Haba names herself 'Friend No. 1'. Just as they agree to coexist peacefully, a mysterious new transfer student arrives, setting the stage for an unexpected twist in their intertwined destinies...

Amidamaru was turned into stone by Rika's hands. Hana, who has no more spirits, is hit by Ryuji's special move « Wal no Ryofu » and faints. Rika uses Ryuji to try to stop Hana from dying to its roots. Seeing this, Haba realizes that her sister is being manipulated by something and tries to release her oversoul, but...

A flower that experienced death in the past and was brought back to life by Hao. The condition was that the flower would possess the power of a demon, and that power would be activated when the flower was on the verge of death, so that it would never die again. Hana learns this fact and becomes depressed. He realizes that he can't do anything without Amidamaru, and he becomes keenly aware of his own helplessness.

Hana wonders who she is on a hill above the cemetery. She realizes that Gakko Ibuki, a Yankee-style shaman who suddenly speaks to her from behind, has picked a fight with her, and she prepares for battle. Hana counters Gakko, who unleashes Oversoul NAMA-HAGE, with the "demon" that resides within her. Gradually, Hana loses her sanity and is absorbed by the power of a giant demon.

Just when Gakko and Namaha think they have conquered the power of the demonized flower, they find themselves in a pinch when faced with the demonized flower again. At that moment, aluminum appeared... Aluminum calls Gakko "Team Hao Anti-Demon Division Commander," and introduces Haba, who has joined them, to Gakko as "a member of Team Hao." Hana and Haha don't know what's going on, so Alumi begins to explain about "Flower of Maze."
