Kasukabe Tsumugi (春日部(かすかべ)つむぎ) is a Japanese vocal synthesizer character developed by the KasukabeTsumugi Project. She is capable of speaking and was released for the VOICEVOX text-to-speech software in November 2021.[1] She was released via a limited lottery application in September 2023 for the VOCALOID β-STUDIO VX-β engine and is now expected to receive an AI voicebank for VOCALOID6 in the winter of 2024.[2]

Her voice is provided by the Japanese Virtual YouTuber Kasukabe Tsukushi (春日部(かすかべ)つくし) from Virtual Saitama (バーチャル埼玉; Bāchuaru Saitama). As a Virtual YouTuber, Tsukushi made her debut in February 2018 and was formerly part of company Activ8's in-house agency upd8 (which also managed Kizuna Ai before she got her own standalone company) before its cease of operations in December 2020.[3]

Concept[]

Kasukabe Tsumugi was created as the cousin of the YouTuber Kasukabe Tsukushi. She was born in the Saitama Prefecture like her cousin.

Appearance[]

Kasukabe Tsumugi has a rather scruffy looking appearance. She has messy platinum blond hair tied in a single pigtail on her left. She loosely wears a light brown school jacket covered in pins and band aids which is somewhat draped under her left shoulder. The jacket also has a black with pink borders armband on her right side. She has a yellow scrunchie on her right wrist over her jacket. Her shirt is a dark grey dress shirt which is not tucked into her skirt and unbuttoned slightly at the top. She also has a slim and very loose golden tie with another band aid at the bottom. She has a dark pink plaid short skirt with a pinkish off-white border towards the bottom. She wears black dress shoes and white legwarmers that go up to her knees. Her nails are painted cyan and she wears a silver necklace. She also has light blue eyes.

For her VOCALOID β-STUDIO design, her jacket is taken off and tied around her waist, while the scrunchie is nowhere to be seen.
