Tsuina-chan (ついなちゃん), also known as Kisaragi Tsuina (如月ついな), is a Japanese vocal developed and distributed by AH-Software Co. Ltd. in collaboration with Tsuina, the Ogre Hunter Project, and released with Standard and AI voice databases for Synthesizer V Studio in November 2021.[2][3] She was originally released as a VOICEROID2 product on November 1, 2019.

Her voice provider is Mai Kadowaki, a Japanese voice actress and radio show host.


Tsuina-chan originates from a popular "meme" character in the online Japanese anime community - Hinomoto Oniko. Oniko was created by denizens of 2chan in order to combat a particular Chinese ethnic slur against Japanese people by using that term and making it into a "cute anime girl." By doing so, they would "embrace" said term and make it useless as an insult.

She is the first VOICEROID to have both standard and Kansai-ben dialects, the second of which is due to a stretch goal for her crowdfunding campaign having been reached. Previously, this was achievable with Kotonoha Akane & Aoi, but as two separate characters.

Tsuina-chan resulted from a member of the "Hinomoto Oniko Project," Saki Oohenri, wanting to create a "rival" character to Oniko - as Oniko is a ogre, Tsuina-chan was conceptualized as a ogre hunter. Tsuina-chan made her official online debut on Oohenri's pixiv on February 3, 2011 (the initial upload has since been deleted, however). Her character is inspired from the "Tsuina" Event, which is an annual ceremony performed on December 30 each year. It is a ceremony designed to exorcise ogres/bad spirits, which is the basis of Tsuina's character. Elements of the ceremony (instruments, wooden masks, traditional clothing) are all part of Tsuna's character design.

In November 2021, Tsuina-chan had an update to her website and more details about her character were given. Her blood type is "O-ni".


Her real name is "Kisaragi Tsuina" (如月ついな), though she's also commonly referred to as "Enno Tsuina" (役ついな or 役追儺). She prefers being referred to as "Enno" as she considers it cooler than "Kisaragi" (which she is embarrassed by).[4]

Kisaragi (如月) is an outdated term referring to the second month of the year, known as February. Tsuina-chan's original online debut was February 3rd, which is also her character birthday.

Enno (役) can be translated to "role," "duty," "responsibility," etc. When combined with the kanji of Tsuina's first name, 追儺, which means "the ceremony of driving out evil spirits", her full name can be translated to "the duty of driving out evil spirits," which is the basis of her character.

Her name is rendered in kana as "ツイナチャン".[5]


Kisaragi Tsuina is a petite fourteen-year-old girl with long pale pink twindrills. A curly ahoge sits atop her head. Her oni barrette is made to look like Dickson, her ogre mask. Tsuina has bright yellowish-brown eyes. For her Simple (also known as Diva) outfit, she wears a black and red sleeveless shirt with a white sailor collar tied with a red kerchief. The front of her top is lined with gold buttons. Around her waist is a white obi tied to the side with a pink obijime. She wears black detached sleeves with red feathery fringe. Her skirt is short and black. The pleats in the skirt are a crimson color. Two blush colored bars glow on the skirt’s hem. She has two different sock lengths: the right being a knee-sock, and the left being an over the knee sock. Her Zori are black with pink straps.

In her Standard design, the outfit is near identical to her Diva design except for the addition of detached black and red sleeves, that begin thin from the top, then greatly widens at the end, and the sheer pink fringe at the hem of her skirt. In her AI design, the obijime and zori straps are red and she wears an orange karaginu instead of the detachable sleeves.
