A shy girl who dislikes standing out. Admiring her older sister Shuura's band, she secretly started performing as a faceless singer online. While active in the group "Go-Spell" with creators who recognized her talent, she was discovered by her sister and relentlessly scouted for Jack-Pot. Though initially reluctant, she was captivated by the experience of making music together and joined the band. She is Shuura's younger sister. Age: 16 (High school freshman) Likes: Singing Dislikes: Strong-willed/aggressive people Reason for not transforming (into a dragon girl): Because it stands out too much. Speech style: Speaks in a very nervous, hesitant manner. First person: I (Watashi - polite/soft) Calls Shuura "Sis" (Onee-chan). Addresses others mostly as "-san."

A highly communicative and kind "shadow leader" who is skilled but occasionally airheaded, always supporting the members from behind the scenes. In her freshman year, she energized the school as a vocalist. She loves seeing a crowd get excited and everyone having fun, so she's the type who doesn't mind not being the frontwoman. Usually, she has a kind, big-sisterly personality, but she has a terrifying side when angered that everyone fears. She is Mizuki's older sister. Age: 17 (High school sophomore) Specialty: Finding hidden talent Dislikes: Tense/hostile atmospheres Reason for not transforming: Because things would get out of control. Speech style: Speaks with a gentle tone. First person: I (Watashi - standard) Second person: By name

Zana and the other second-years happened to find her at a live show. Despite her superhuman guitar techniques, she was kicked out of her previous band due to poor communication skills.

Her private life is a mystery; even her bandmates know almost nothing about it. Age: 17 (High school sophomore) Likes: Guitars Reason for not transforming: It gets in the way of playing guitar. Speech style: Quiet, but occasionally makes very pointed remarks. First person: I (Atashi - casual/feminine) Second person: By name
