Meltdown by Rin Kagamine and Onii Yuukai by Luka, Miku, Rin, and Kaito.
I hate how much I like Onii Yuukai. I dunno if any of you have seen the video on Youtube (it's called, like, [Vocaloid Sisters United] Onii Yuukai [English Sub] or something like that), but there's this one frame that appears for a split second showing Miku, Luka, and Rin looking REALLY CREEPY. Because they're totally about to rape their brother. Why yes, that IS a really weird song. My sister managed to catch the image and it looked so funny (Miku and Luka's faces were so derpy) that I laughed so hard I cried. We both took pictures on our phones.
And that was Grace's Unintelligent Short Rant of the Day.
