Yes according to the MMD videos
Officially they are not related. Unofficially however, fans like to make Miku the little sister of Kaito.
I'm pretty sure she doesn't have one but she's often paired (by fans) with Kaito or Len.
Rarely, in some PV's of what Kaito sings is mostly about a girl. She can be mostly used as Miku. We do not know why. But mainly, as my own opinion that Kaito may like Miku Hatsune at some points. Miku Hatsune sings in her PV's songs about a guy, and he has brown hair with brown eyes, so she probably doesn't like him. As one of my friend in Japan has researched that in MMD Cups (Yes they are fake sometimes but they're mostly about the comedy) Kaito hangs round with Miku Hatsune as her friend, they get quite close in some points by Kaito taking care of her little sisters. Although, Kaito MIGHT go out with Meiko we never really know the truth. There is a MMD that Rin and Len tease Miku for massaging Kaito's back.All due to a silly game of course from Chibi Miku...The reason why people say Miku x Kaito is probably what your thinking, it is the fact of while other Vocaloids were selling at ten-thousand average, Kaito would only sell within the five hundreds. Due to having a rougher voice and because fans would previously lacked the interest in male Vocaloids, he sold very little and was considered to be a failure, to there for be cancelled. When he started to sing a song with Miku Hatsune, people started to love the couple Miku x Kaito. Without Miku, Kaito would've been deleted. Miku somehow saved him from being deleted, by his voice data and that's why Kaito is still out now today. OR Miku may like Kaito, by saving his data? Probably?The honest reason is think whatever couple that you think that suit in Vocaloids is in your imagination.(I don't want to get any dislikes on this answer I tried my best to write this)
Maybe it's "Higurashi No Naku Koro Ni" - "YOU" or "Dear You"
no not officially by anyone in pvs she is usually parried with kaito or len, but it is really up to the fan to decide who she may like or who they want her to like so who she likes is up to you it could be kaito or even len
Miku Hatsune and KAITO vocal packages for the software VOCALOID. It's like saying variations of the same books are the same. They're inimate, and they don't have relationships. It just depends on the arist/author etc.
There was just an extra chapter about Kaito and Luchia's wedding.Nothing special.
Miku hatsune is not officially parried with anyone she is just an awsome character and does not have a certain personalty she is usually parried with kaito or len by fans so the fan his or hers self can decide who they want miku to be with it could be kaito or len.
No, you may ship her with whoever you please. Personally, I like Len x Miku the most but I am a multishipper
Kaito Shion (Shion Kaito) is supposed to be a Vocaloid, but he is not an 'official' Vocaloid. He has blue hair, and seems to have a fondness for scarves. He adores ice-cream and it is his character item. He is supposedly very close to Meiko Sakine (Sakine Meiko) but unknown whether as good friends, or 'siblings'. He supposedly has a VOCALOID programme, but it is not released. He is often featured as Miku Hatsune's (Hatsune Miku) lover, and the pairing grew in popularity when the song 'Canterella' was released, featuring several different music videos telling the same story.
Vocaloids, in this case Miku, do not have a defined relationship or personality. She could be single. She could be married. She could have a boyfriend/girlfriend. It is up to the fans and music producers, artists, and animators, to decide. It is rumored that she and Len like each other. ABSOLUTELY NOT!!! Miku and Kaito like each other and I have proof.
