Miku & Luka (info)

(NOTE: This is not suggesting that I ship Miku and Luka!!!! I am very open to various Vocaloid ships because they don't have set personalities or relationships, since they're computer programs that are meant to be blank slates. I am only listing Miku and Luka together in one post to save space.)
