She has a play/pause tattoo (▶ ll) located on her left cheek. The little droid that accompanies her acts as a pet, microphone and speaker; on October 16, MAIKA's Facebook page started a poll asking fans to give a name to the floating droid. Later, on December 22, the site stated that the winning name was "NOVA"
It was reported via a YouTube video that MAIKA's design was made to look mature like MEIKO's. However, it was accepted that MEIKO's design was a little plain, and so Noriko Hayashi went for a design that was more like Lady Gaga. The hairstyle was a main focus in the design. Due to the number of female Vocaloids out, it was felt that if the hair was not something bold, MAIKA would not stand out. The lineart was completed first; Voctro Labs requested Noriko to adjust the hair color scheme. The last one was to avoid comparisons with previous Vocaloids like IA or Luka, as originally, the hair was a gradient of peach to light pink. Noriko tested various color combinations with Voctro choosing the final color scheme. She was asked also to make MAIKA look a little happier, so her face was adjusted slightly. NOVA was purposely created to make her design different from other VOCALOIDs. The design itself did not pull any references from Spanish culture, as it was decided that a more international feel would make her more approachable by non-Spanish people and would avoid racial cliches.
On February 25, 2014 Voctro-Labs started an original song contest with the purpose of promoting MAIKA. The deadline was set for May 19, 2014 and the judging will begin on June 1 of the same year.
The winners of the contest have since been chosen and have received their prizes, with the first, second and third place winning videos going to "La Audición" by Maubox, "Fujioshi" by darkbluecat and "Define Me" by nostraightanswer (Kenji-B). The two favorite videos selected by Voctro Labs included "Tiempos" by YZYX and "Define Me" by nostraightanswer (Kenji-B). There were also 16 other videos in the "Special Mentions" section of the contest results. The final rankings and exact totals of results can be found here.
