Princess Nesty is one of the eight Princesses of Valhalla. She commands an anti-pirate space fleet, actively pursuing corsairs and criminals across the galaxy to maintain order and security. Her primary duty involves leading this specialized force. She occasionally visits Earth, intersecting with the main characters at the Tokino Bathhouse. During these visits, she interacts with other Valhallan royals and associates like Valkyrie, Hydra, and Sanada. Her role as an anti-pirate commander leads to occasional clashes with factions such as Sanada's Cat-Girl Maid Squad when their activities conflict with her law enforcement duties. Visually, Princess Nesty has red hair cut to ear length and yellow eyes, consistent with her adult age. Her narrative focuses on her space fleet operations and intermittent engagements during Earth visits; her established role remains consistent.
