Super Sonico (すーぱーそに子) is a playable crossover DLC character in Senran Kagura: Peach Beach Splash. She was created by Tsuji Santa for the Japanese video game company Nitroplus, first appearing as a mascot for their music festival "Nitro Super Sonic".
Sonico is an attractive young woman with dark pink eyes. Her straight, pink hair is cut at the waist, and has bangs that cover her forehead, pushed out of her eyes and falling down the bridge of her nose. She is always shown wearing her signature wireless silver headphones on her head.
Sonico has a sweet, polite disposition and is always willing to work hard at everything she does. When she was younger, she was very shy and wasn't willing to put her out there and follow her own passions. Later, she became a gravure idol and the front-woman for her band First Astronomical Velocity which helped her gain more confidence. Despite this, she can still get embarrassed by some of the outfits she has to wear for work and her efforts to be helpful can get her into situations she finds hard to handle.
- Super Sonico is written as 'すーぱーそに子', which could mean 'Super Sound Girl' or 'Supersonic' (as in supersonic sound). She is named after the music festival "Nitro Super Sonic".
- While Sonico is voiced by Ayano Yamamoto, Sonico usually credited "as herself" in her various media appearances.
