Lulu LurkHeart

On stream, Lulu is silly and mostly unserious. She enjoys making jokes, referencing memes, and interacting casually with her audience.

Despite her divine backstory, her demeanor is approachable and humorous, making her streams fun and lighthearted, though she does not stray from talking about real life topics or her experiences.

Her YouTube channel was created on 5 December 2021.

From 2021 until around 2024 she tested the waters of social media content creation and streaming, but didn't fully dive in until 2025.

In December 2025 she started as a pre-debut VTuber, using a model by Shibutani.

Once a priestess in a small ocean village, Lulu sought to stop the community from sacrificing more people to the sea. She offered herself as tribute, and the sea transformed her from human to demigod, crowning her the princess of her village. Her story combines themes of selflessness, rebirth, and mystical ocean magic.
