Life seems to have returned to normal for Tsutomu, who has no memory of his alter-ego Birdy and believes that everything that happened was just a dream. He reunites with his friends, particularly his close friend Natsumi Hayamiya, a cheerful and energetic girl who has harbored feelings for Tsutomu since childhood. Although Tsutomu is oblivious to Natsumi's affections, their reunion is still a heartwarming one.

In contrast, Birdy finds herself trapped in an unfamiliar world where she no longer possesses a physical form. With her combat abilities severely limited, Birdy is frustrated and longing to regain her full power. She receives a visit from her superior, Gomez, who informs her that she will be working undercover on Earth to track down the remaining alien threats that have infiltrated the planet.

Meanwhile, Tsutomu's peaceful school life is disrupted by a series of bizarre incidents. Unknown alien organisms called "Necks" start appearing and wreaking havoc across the city. These creatures possess unsuspecting individuals, turning them into mindless hosts. Tsutomu, along with Natsumi and their classmate Hayami, gets caught up in one such incident when a Neck takes over Hayami's body. With their lives at stake, Tsutomu and Natsumi must find a way to save their friend from the alien's control.

Just as the situation seems dire, Birdy unexpectedly makes her entrance, albeit in a holographic form visible only to Tsutomu. She lends Tsutomu her strength, allowing him to transform into his alter-ego and merge with her body once again. With their combined powers, they confront the Neck-infested Hayami head-on.

A thrilling battle ensues as Birdy and Tsutomu showcase their extraordinary agility and combat proficiency. Their seamless teamwork and synchronization prove to be crucial in overcoming the threat. However, as they defeat the Neck, a powerful blast engulfs them, leaving their fate uncertain.
