Hyperdimension Neptunia Wiki

Don't you understand? Without justice, you have nothing.
— Ryuka



Ryuka has blue eyes and long brown hair, worn in the side in a big spiraling, loose ponytail with a pink-red flower on the side. She wears a red top with a dark red-black spiraling dragon and a few buttons, with only one being together to reveal her breasts and belly button. At the collar is a gold badge with a red rose decal. Over this, she wears a white jacket with red cuffs and black lace lining a white skirt with a dark red slit on the side and a black belt, sheer pantyhose with white, black, and red leg warmers, and a pair of white and black platform heels with rubies on the toe.


A caring elder sister type good at taking care of people, with a coherent personality. She has no mercy for those who endanger her friends. Since she speaks in a mocking tone, she makes enemies without realizing it.

  • Her name is derived either from the Yakuza series' Japanese title Ryuu ga Gotoku, (which translates to "Like a Dragon") or the name of the main character, Kiryuu Kazuma.
  • Her weapons are all references to Kazuma Kiryu, the main protagonist of most of the Yakuza games.
    • Sake is a common type of alcoholic beverage in the Yakuza series, found in practically every bar in the games, and one of her attacks references how it serves as a powerup item to Kazuma in combat.
  • Her personality is largely based on Kazuma's.
  • Her outfit is a feminized version of Kazuma's classic white suit and red shirt, and the dragon motif on the front references Kazuma's dragon tattoo on his back.
  • Her CG scene with Noire in a hostess club is a reference to an event Kazuma can be part of in the Yakuza games, where he has to work as an attendant at a club and can even run his own.
