Megurine Luka

Megurine Luka known in the west as Luka Megurine is one of the patriarchs of the Vocaloid Household and a reoccurring yet minor character.

Despite being one of the heads of the house she rarely spends her time there and rarely stays for long. This is due to her intense hatered for the insanity of the household and its inhabitants.

She fears that if she stays for to long she will lose her mind like them and become an odd abridged version of herself, but makes sure to come back every now and then to check in on things and make sure everyone is okay.

She hates her younger possible sister Miku Hatsune's pet Alligator Gypsy with a passion as when ever it sees her it chargers at her and eats her. This is due to Gypsy's intense hatred of the color pink, something that Miku herself is aware of but still insists that Gypsy only does this because "she likes you(luka)!".

Recently she was involved in an event where an imposter of her broke into the house insulting her 70's power ballad "Luka Luka Night Fever" and violently pooping in one of their bathrooms. Luka proceeded to murder the imposter.
