no she does not miku is usually paried with kaito and other boys like len
it is not officially said. there are some kaito x miku fans, there are some kaito x luka fans. there are other kaito x other vocaloid fans.
no
I think Miku is more popular, but personally Luka is my favorite.
You can search around youtube or VPVPWiki, you can also try a search on Google like MMD Luka download.
go to diviantart.com then type in Luka MMD and you will find some different downloads of her hope this as helpful ;)
Let's hope this answers your question: Miku, Rin, Len, Meiko, and Luka are all Vocaloids. Vocaloid is a software from the company Yamaha (the people that brought you motorcycles). Vocaloid is basically a voice adjuster I think. Miku, Rin, Len, Meiko, and Luka's voices are Vocaloid BUT their virtual bodies are on a big screen. They are basically animated humans on a big TV. Again hope this answers your question!
Why, Luka is obsessed with tuna, is because that is her character item. like miku and leeks. Rin and roadrollers. Kaito and ice cream......etc.
Officially none of Crypton's vocaloids are related. So Hatsune Miku does not have a sister. However, fans like to make Meiko, Kagamine Rin, and Megurine Luka her "sisters".
Hatsune Miku's is World is mine OR PoPiPo. Rin Kagamine's is Meltdown or Tokyo teddybear. Len Kagamine's is Spice! or Servant of evil. Luka megurine's is Just be friends or Luka Luka night fever.
Project diva one has songs mostly featuring Miku. There are only about 4 len/rin cover songs on there. Also most of the models are Miku. In PD2, They focus on Luka, miku and len/rin. Also, the arrows and a "hold" not was added.
Miku doesn't really like Katio. Kaito already likes Meiko so there's no point for Miku to love him. SHE LOVES LEN
Well, I absolutely LOVE the Kagamine twins. They're cute and have wicked creepy songs. Second, of course, is Miku. I mean, how can you NOT love her? I also like Gumi....she's the vocaloid that sounds the best. Luka is cool, too. Her songs are funky and disco-beat.
