Meiko is gr8 and she's better than Haku. She's better than nearly all the Vocaloids since she has a really mature and beautiful voice. I'll bet you only hate her since you like KaitoxMiku, which is a really stupid reason to hate her.
It's just my opinion. She is my least favorite vocaloid when it comes to pairing. When it comes to singing, she should be ranked 03 instead of Luka. I just get upset when Meiko is within 12 feet of Kaito because I am a MikuxKaito fan, always have been and I'm sure I always will be. I don't just leave Meiko alone to be unpaired, it's that fact that I don't pair her with a guy. I'm not THAT cruel to her even though it may seem like it.
I barely ever ship her with Kaito anymore lol i ship her with Luka now because they're such cutie pies together i thought you like hated her because of the pairing and insulted her voice because of it that's what i thought
