Characters of Black★Rock Shooter: Innocent Soul
A girl who watches over Hazama.
- A-Cup Angst: When Let tells Io that eating carrots will make her bustier, Rock swallows an entire piece. And she strangles Ron for calling her flat-chested during their "ventriloquist act".
- Berserk Button: Flips out when she hears the word "Disappear". The reason? Some bullies burnt her shoulder and leg with cigarettes while chanted the word in her Dark and Troubled Past, only starting to appear as flashes of memories after being in contact with a corrupted soul who died in fire. Before that, she has no reason other than instinct why she hates the word.
- Boke and Tsukkomi Routine: With Ron.
- Death by Falling Over: Her mortal self died from injuries sustained from being pushed down a flight of stairs.
- Defrosting Ice Queen: Eventually.
- Emotionless Girl: Has difficulty recognizing what "fun" is, and utterly confused why she has tears leaking from her eyes after seeing her previous life. She's not quite content with this, however.
- Gender-Blender Name: Here, B★RS is called "Rock". She is also the legendary "Black Star".
- Good Is Not Nice: She knows what her mission is, and she offers no consolation to Reto, who just realized that he's a dead guy all along. She becomes nice through Character Development, to the point that she consoles a fading Dead by acting as her fiance

- Sugar-and-Ice Personality: She's easily the most emotive B★RS, though she has an air of stoicism to her.
