"Ahoy! Houshou Pirate Captain, Houshou Marine here!"

Loves jewels, treasure, and money. Her dream is to become a pirate and go treasure hunting. In order to get a pirate ship, she is now stacking up money as a VTuber on the great lands, just like how the other land-lovers do (which also means she is currently just a girl cosplayer).
She acts like a big sis and sometimes seduces people like a succubus does.

From unraveling the secrets of opening and closing doors to defusing surprise packages more commonly known as bombs, there is never a dull day at the Hololive Production office! Holo no Graffiti follows an eccentric cast of Virtual YouTubers, also known as "VTubers," going about their absurd yet hilarious daily lives, detailing all their cute moments and mishaps.

In order to defeat a "Collapser", these streamers are given the power to transform into magical girls called “holoWitches” and spend their days fighting to defeat Collapsers and save those who have fallen into a "Yumeochi" state.
