Otomachi Una is a Japanese VOCALOID developed and distributed by Internet Co., Ltd. in collaboration with MTK Inc., and was released for the VOCALOID4 engine.
She is a young girl with very long blue hair tied into low twintails with braids on the ends, long bangs and an ahoge. She has blue eyes and a fanged smile.
With the release of this character came three designs, two for the VOCALOID voicebank "SUGAR" and "SPICY", and another for TalkEX (a text-to-speech program):
- SUGAR features Una in a band uniform with a sailor collar and red necktie and a white pleated skirt. She wears white socks and blue shoes. Around her left thigh is a gold thighlet; this matches her gold bracer.
- SPICY is altered to be more punk in theme. Consisting of a black jacket, red tie, and white shirt that shows her navel. She also wears belts, a single fishnet thighhigh attached to a single legwear garter paired with a purple thighhigh with piano print and black shoes .
- The TalkEX design features Una in a sailor dress, plaid black pantyhose and white sneakers. Her accessories are red-framed eyewear and a wristwatch. This design was also reused for her later VOICEROID voicebank.
All three looks have her wearing a puffy eel hat.
