CUL (カル) is a Japanese VOCALOID developed and distributed by Internet Co., Ltd., and was created in collaboration with VOCALO Revolution. CUL is their mascot character and she was released as a VOCALOID in December 2011 for the VOCALOID3 engine. Her voice is provided by Japanese female voice actress, Eri Kitamura (喜多村 英梨; Kitamura Eri). She is a "Character Voice" type vocal.
She was introduced in "CUL makes Revolution!". CUL was featured in the shows introduction, the PV "白の季節" and the closing credits of the show. CUL was also the mascot of "CUL project; offical", a website designed to promote CUL to make her official. Stickers were also released on sale featuring her. The MMD model used in her PVs, such as "CUL makes Revolution!", was later released. CUL also appeared alongside 秋元結衣 in a music video that later made it to DVD.
As part of promotion, CUL has had several drinks named after her, both alcoholic and non-alcoholic, as well as a chocolate dish. These include the "Bloody CUL", "CUL and Milk" and "CUL Chocolate".
A contest was held on 2nd Dec, 2013 by VocaloTracks to create an original song using CUL. Her initial deadline was 1st Jan, 2014 but was held back due to system errors, the new deadline is 14th Jan, 2014. Winning songs will be able to sell their songs under a "professional label".
Since CUL's existence as a VOCALOID is owed to her fans, CUL already had an established fandom prior to becoming a VOCALOID. She has had much support and publicity within the Japanese fandom and this has resulted in her overall reception being positive. However, this made her one of the more popular releases for VOCALOID3 at the time.
