Roca's Introduction.
Profile[]

But, you wouldn't mind right? (Welcome to my channel! Here, I'll take you along on all my live-streaming misadventures. It'll be lots of fun!)
Personality[]
Roca does her best to make her public vibe and dance with her big chuuni. She has a teasing/sadistic showing often, and she will often push her fans to call for an encore at the end of her karaoke. She enjoys presenting herself as an evil being, even while being bombed with love and compliments by her chat. Her fans often get roasted for not making enough compliments. She will make fun of her chat by various means, even outside of her streams where she acts in roleplay. Still, she appreciates moments of calm and sincerity on serious topics, and feels happy being supported. She genuinely is humble.
Because of knowledge, memories and tastes she usually shares, Roca appears being into all sorts retro things: TV shows, music, and even games. This way, she doesn't talk often about recent pop culture. She enjoys talking a lot and sharing experiences, but she may accidentally twist the meaning of a phrase, which leads to funny quiproquo.
Roca likes facing a certain level of challenge in games, but she also tends to swear quickly when events take an unexpected turn. Despite her talent for singing, she does have fear of stage and gets easily nervous in situations she feels judged. For example, during the first the first global idol Among Us collab, she turned out unable to lie credibly.[1] If Roca struggles excessively in a stream, she might feel shame because she couldn't deliver her best.
Appearance[]
She has dark pigtails with streaks of purple throughout and eyeballs as well as various other hair accessories. On her right ear is visible an imp earring, which is actually her mascot. She wears rebellious teenager clothes tinted in nuances of purple and black. Her crop top shows off her midriff. She has a skirt with rips and accessories. On her back are bat wings and a long thin devil tail. Her earring is the figure of her fans, a JamStone.
She can change the size of her pigtails, from very short to long or very long.

Lore[]
- In 2405, inside a laboratory, two super villain rats, Winky and Brian, were scheming into take over the world. Brian was about to test his new massive destructive weapon: a ray capable to give life to anything. While Brian was distracted over his pet rock, Roca, Winky accidentally opened fire and hit Roca.
