Ryoko Kaminagi

The heroine of this work. 16 years old. Height: 160 cm. Weight: 46 kg. She lives across from Kyo's room, making her his neighbor and childhood friend. Her hobby is filming video movies, and her dream is to become a film director. With a bright personality, she has the talent to attract and soothe those around her, gradually drawing them into her pace.

She has had special feelings for Kyo beyond just being childhood friends for a long time. Even after they become mutually affectionate, she remains concerned about Kyo's past relationship with Shizuno. Through her interactions with Kyo and Shizuno, her strong curiosity and sharp intuition help her awaken as a Celebrant. From then on, she becomes Kyo's Wizard, showcasing her talents as a Witch and fighting alongside him.

She dies after being ambushed while piloting the Altair. Her remaining data is salvaged but cannot be fully restored, leaving her in a comatose state within the Maihama Server during peacetime. After her phantom body is repaired by Shin, she recovers from the coma but loses her emotions (though she returns to normal within the Zegapain Altair). She regains her emotions after being downloaded into the Maihama Server while piloting the Zegapain Altair.

In the final scene of the last episode, a pregnant woman who appears to be Ryoko speaks to her unborn child, saying, "Hurry up and be born. The world is full of light." There are theories that this woman is Ryoko, who was united with Kyo due to the early completion of the Resurrection System, or that she is a descendant of Kyo and Ryoko. There are also theories about the unborn child, including that it is Kyo and Ryoko's child, Shizuno who couldn't materialize and thus became Kyo and Ryoko's child, or a descendant of Kyo and Ryoko. Some theories even suggest that Kyo died of old age before Ryoko could materialize, leaving the identity of the woman and the unborn child unclear.

In the drama CD version, her voice data was damaged during a transfer from the Maihama Server to the Oceanus (equivalent to losing her voice in reality), and her voice was temporarily replaced with Talbot's voice data until Shima whimsically repaired it.

In the movie 'ADP,' she shows signs of awakening as a Celebrant midway through and glimpses memories of the future (her activities in the TV series).

In the novel 'Entangle: Girl,' she was filming an independent movie titled 'A Summer Day at the End of the World' with the film club. After the reset, she awakens and learns that Chiho and Kanou, who made the movie with her, have been lost.
