Ibaraki-dōji is a character from the anime and game Onigiri, who joins the main party as the fourth member upon their arrival in Kumaso Village. She is a half-oni, a fact that establishes a significant connection with the player character, who shares the same hybrid nature.

Her personality is defined by a playful and cheerful demeanor, as she is rarely seen frowning. However, this lightheartedness is balanced with a selfish streak and a powerful addiction to alcohol, which she values even more than a good meal. These traits give her a somewhat unpredictable nature. She carries herself with an adult and temptatious aura, often wearing fashionable yet skimpy clothing, and naturally falls into the role of an older sister figure within the group.

In terms of her role and abilities, Ibaraki-dōji is not just a fighter but also a travelling bar owner, a profession similar to Miroku's status as a travelling merchant. Her primary expertise lies in her skills as a sommelier and a master of liquor creation and mixing. She can produce a wide variety of potion-like alcoholic drinks that grant special temporary stat boosts to the player, such as increased movement speed or damage output. Her abilities in this area are extensive; with the right recipes, she can even create resurrecting alcohol. The range and quality of the drinks and sake bottles she can provide expand as her affection level with the player increases. In battle, she wields a weapon called the Cat-paw Katana, a sword with a short reach that allows for a fast attack speed and good damage output.

A notable physical characteristic is that the cat-like ears on top of her head are actually her demon horns, and true to her feline aspects, she has a weakness to catnip. She is also frequently mistaken for a cat capable of transformation, though this is not an accurate description of her nature.
