Marine's introduction.]]

Personality
Marine is a bold, fast-talking girl who often throws caution to the wind, making obscene jokes and playfully mocking her higher-ups. Even an action as simple as eating a hamburger can be twisted into a dirty joke. She loves money, jewels and treasure, and according to her backstory, she decided to become a Vtuber to get money to buy her own ship. As such, Marine is officially a cosplayer and not a real pirate.

Though she claims to be 17 years old, her self-described "granny" voice, lack of physical stamina, and extensive knowledge of 2000-2010 Internet culture indicate that she is almost certainly older than she claims she is. This is supported by Natsuiro Matsuri's habit of teasing her about her age.

She greets her viewers with "Ahoy!" a typical pirate greeting.

Background
Her Twitter account and YouTube channel was created on 22 July 2019. She debuted with her introduction stream on 11 August.
