Megurine Luka 𝜗ৎ

In the Empty SEKAI, Luka attempts to "break the status quo," and enjoys stirring up trouble and tempting the other VIRTUAL SINGERS.

Luka has blue-purple eyes and long pink hair, worn loose with an iconic strand falling to her shoulder. Her fingernails are azure blue.

She wears a black sweetheart corset with gold buttons on the center and is tied with black ribbons on either side of the waist. Underneath, she wears a sleeveless gray dress with black stains near the bottom. At the top, it has ruffles that cover the corset top. There is also a black net that is attached to the dress and makes a collar. Her skirt is torn in many areas thus making layers at different places. The layers are gray with black stain, ruffled purple and black. On top of it, a small black cloth attached to the corset covers the right part. She also wears black knee-long socks. On both her arms, she wears a short gray with slight dark stain arm cloth which is ruffled. It also has a ruffled border at the top.

Like all the members, a red string is tied on her right hand and the net of the dress. She wears a white hair bow with a gray ribbon tied on the left side under which a purple ruffle net is present. Her eyes are slightly dark.

Hatsune Miku: In the Empty SEKAI, Luka finds Miku's habit of showing everything she gets from the members of Nightcord to all the Virtual Singers adorable, though also making some fun of her worry for them, saying Miku would cry if Kanade collapsed again[3]. She also respects and appreciates Miku's will to help all of them, especially Mafuyu. Miku is thankful for Luka being the ones that keep everyone in one place so they can spend some time together and coming up with new activities in the SEKAI.

Kagamine Rin: In the Empty SEKAI, Rin is annoyed and perplexed by Luka's judgments, ideas and tricks on her, where Luka sometimes gives her the truth of problems she's annoyed with in a smug way with this back and forth scaring Len. Rin also assumes that Luka and MEIKO are always fighting due to their opposite ways of thinking. Luka isn't afraid to slightly mess with Rin, such as fiddling with her hair without any warning. Rin sometimes fights back with remarks, though Luka takes them as facts and thinks on them.

Kagamine Len: In the Empty SEKAI, Len is somewhat afraid of Luka, especially when's she's paired up with someone like Rin. He gets overwhelmed when they both kicker. Though Luka does try to be nice to Len, admitting she'd love to help him at times but can't, and giving him advice on how to help others.

MEIKO: In the Empty SEKAI, the two have been at odds with each other due to their differing methods on the way to guide the members of 25-ji, Nightcord de. However, they have been starting to not be constantly at war with each other, somewhat due to MEIKO trying to ignore anything she says.

KAITO: In the Empty SEKAI, despite KAITO being the more brash one of the SEKAI, even he cannot put up with Luka's tendency to be irritating to others and gives up on arguing with her when he can't think of anything to say, which she herself finds amusing.

Luka and the other Virtual Singers live in a world called Empty SEKAI, and people who often visit them through the real world are "25-ji, Night Code de." Kanade, Mafuyu, Ena and Mizuki. The creator of "Empty Sekai" is Mafuyu. "25-ji, Night Code de." is a musical group. Virtual Singer: Miku, Rin, Len, MEIKO and KAITO.
