Mikuuu, would you like the last bits of meat? There is still plenty if you suck all over the bone. There is some of Oniisan's saliva here and there, but it's okay.If only you really were dead.Miku was delicious.If only you were dead.It really doesn't matter, but "meat" and "Miku" sound somewhat similar, don't they. So this is what Miku tastes like in comics! So delicious. Just kidding.
Meat is pronounced "niku" in Japanese. If only you were dead.
Likely a reference to the song of this name, the music videos for which has Kaito repeating this line dozens of times in a disturbingly cheerful manner.
