Full Profile
Haku Kuroa is an active Japanese independent VTuber who debuted on 2025-07-27. Her character is built around a mermaid who gained a human form, with blue, ocean, mermaid, and gaming themes forming the clearest parts of her public identity. Her Live2D model is listed at 158 cm, and the name Kuroa / くろあ is commonly used as a shorter way to refer to her.
Kuroa is described as being born in the Tsugaru sea and now living around the Yokohama sea. After becoming fascinated by humans, she obtained magic that allowed her to take a human form, but her shy personality kept her from leaving the sea for a long time. She eventually learned that she had many family-like connections on land and began streaming by imitating them, which ties her mermaid lore directly to her streaming activity.
Fan activity is organized around the fan name Shirokuro-tai / 白くろ隊. General posts and messages intended for Kuroa can use #みてみてくろあ, while fan art is split between #白くろArt for all-ages work and #黒くろArt for mature or age-limited creations. Her public preferences include hijiki, edamame, macarons, frappes, and unsweetened tea, while eggplant, tomato, and poorly matched foods are listed among the things she avoids.
