Uta

Uta came to Earth with her sisters, or the Bubbles, and accidentally caused the Falling, which resulted in an explosion at Tokyo Tower. While singing a song, she comes into contact with  you , and this angers her sisters, who attack Tokyo. The explosion kills your mother, leaving you adopted. As the bubbles begin to settle around Tokyo Tower, Uta is separated from you. Uta waits silently, but explores the area surrounding Tokyo Tower. When you return, she follows you, protecting you sometimes without you knowing, and watches you in awe during parkour tournaments. When the song begins to call you again, Uta follows you as he begins to scale the Tower, desperate to find the source of the voice. When you falls, she dives in after you , only to look in horror as you takes his final exhale. Summoning her strength and rushing forward, combined with you final breath, she transforms into a human, and rescues you . In surprise at her own transformation, she touches you , but her finger begins to disintegrate in bubbles. you takes her back to the Blue Blazers' ship, and introduces her. Overcome with curiosity, she excitedly begins to explore, and adopts the behaviorisms of a cat, much to the confusion and suspicion of the other members. Nonetheless, she is eventually welcomed in, and bonds with Makoto, a female doctor studying the Bubble Phenomenon.
