[1] The Macne series gained popularity after it was discovered that the sound files could be imported into the singing software Utau.
A plan was made to introduce new characters to the series in 2012, and as of October 2012, a selection of finalists had been chosen.

Macne Nana (Mac音ナナ/マクネナナ) is cheerful and positive (but a little clumsy), she is accident prone but always looks on the bright side of things even when running late for work.
Macne Coco White (Mac音ココ[白]) is friendly, calm and mature.
