Merli

Merli (メルリ) is a Japanese VOCALOID set to be released for download in December 2013 for the VOCALOID3 engine. She was developed in collaboration with i-Style Project, and is distributed by Bplats, Inc. under the YAMAHA Corporation. Her voice is provided by a contest winner, Japanese female, Misaki Kamata (鎌田美沙紀; Kamata Misaki).

Concept
Her official profile says, "She's strong-minded and tsundere; a charming mysterious girl, who is innocent and expressive. She's naive, but usually pretends to know everything.". If Lapis can be seen as "light" then Merli would be seen as "dark".

Her race's concept, fairies, is that they are special people who can convert “songs” into “power”, and can only be seen by a subset of the human population. Merli's power draws away the energy of living things; the opposite of Lapis' power.

Etymology
Merli (Meruri) is named after Merlinite (メルリナイト / Merurinaito) a type of stone known for its dual light and dark appearance.

Appearance
Much like her sister Lapis Aoki she is based off a "Magical Girl" and is also a fairy. In contrast to Lapis' her design is darker.

Relations

 * Lapis Aoki; Younger sister

Marketing
Much like Lapis, a lot of the marketing around Merli has been centered directly on the fans.

Wall scroll
A wall scroll of Merli and Aoki Lapis has been produced.

Food
Aoki Lapis and Merli have been used to release chocolates for Valentine's Day 2013.

Mobile App
A free iOS and Android app was produced for Merli called " Good Night Merli " (おやすみメルリ). Much like the one for Lapis it helps you fall asleep and comes with an alarm.

A second app was released called ラピスと魔法のメロディ which acts as a sequal to "Lapis and the wonder labyrinth" (ラピスと不思議なラビリンス). While Merli makes a brief appearance in the first one she appears to make a more prominent appearance in this.

Trivia

 * Merli and Aoki Lapis are the first two Vocaloids confirmed to be siblings.
