So...I'm just going to be rating some Vocaloid ships because that's what people in the Vocaloid fandom do apparently.  Don't criticize me and I won't criticize you.

Rin x Kaito: Sorta cute, in a big-brother/little sister way.

Kaito x Miku: Ah yes, the original Vocaloid power couple.  I don't dislike it, but it's not in my current canon.

Luka x Kaito: It can be cute, Acute that is...Hehe...see what I did there?

Kaito x Meiko: YES.  The original Vocaloid character duet (I say character because we don't want to forget about Leon and Lola)

Gumi x Kaito: Eh.  I like Gumi and Len better (blame my Nem obsession)

Kaito x Kiyoteru: ...I guess..if you HAVE to have yaoi.  But mostly indifferent.

Len x Kaito: NO NO NO get this out of here.

Kaito x Gakupo: Again...indifferent.  If you must have yaoi, you could do worse...

Miki x Kaito: Eh.  Indifferent.

Gakupo x Len: Ew.  Get this out of here.  Too weird.

Len x Rin: If you don't headcanon them as twins, go for it.  I still think of them as twins, though.  But hey, you do you.

Piko x Len: I just...don't know how to feel about this.  It just seems a bit too...I dunno, fanservicey.  If you like it it's okay, I just...don't.

Fukase x Mayu: YESSSS.  Crazy Vocaloids belong together.  Mad Hatter, anyone?

Lencest: DON'T EVEN GO THERE.  JUST.  DON'T.

Miku x Len: It's cute but...every time I see them reminds me of A CERTAIN SONG....Let's just say this relationship will not end well for Miku.

Len x Luka: If you put their ages aside, I guess it can be cute...but not one of my favorites.  

Luka x Gakupo: I don't mind it...but after listening to I'll Quit Singing, I just don't know...

Gakupo x Kiyoteru: what

VY2 x Gakupo: What is this, a student-master relationship?  Eh.

Gumi x VY2: Indifferent

VY2 x Rin: Indifferent

Rin x Piko: I'm not sure...I don't think their relationship is quite like that.

Maika x Yohio: Not sure, but it looks cute.  I'll give it a "B"

Fukase x Oliver: Nope.  Next!

Kaito x VY2: Indifferent

VY2 x SeeU: How many of these ARE there?

Might have to skip some...

IA x Mayu: Sort of works, even though it's kinda fanservicey.

Lily x VY2: Doesn't really look bad...

Miku x Rin: Cute but fanservicey.  I like to think of them as clingy best friends.

Gumi x Gakupo: Cute in a big brother/little sister type way.  I don't mind it.

Miku x Luka: If you must have yuri, I guess these two aren't too bad.  

Luka x Meiko: Again, if you gotta have yuri.

Lily x Luka: I dunno...It seems a bit like you're shipping them just because they have long hair.

Luka x Rin: WHO COMES UP WITH THESE?

Len x Gumi: OH YES!!!  Two dorks in love?  A+

Len x Oliver: Are you just shipping them because they look alike?

Oliver x Rin: See Len x Oliver

SeeU x Oliver: REALLY?!

(Okay this is all I can handle.  Think I got all my OTPs out, but sorry, I am NOT ready for this.  Again, don't criticize me and I won't criticize you.)
