Information about VOCALOID relationships is a page for information about the relationship between VOCALOID characters.

Notice in regards to this page

As of 10th December 2018 all relationship questions are being redirected here using the following template:


This is due to the large number of questions that simply ask about the same relationship without looking up to see if the question was already asked and answered. If there is any merit to the relationship of two Vocaloids, it will be noted on this page, so therefore please read this entire page if your question is redirected. It will answer anything that needs to be answer.

In particular if its about the Kagamine Rin/Kagamine Len relationship, its been asked and answered before; such as are they married, twins, lovers, siblings, hate each other, love each other, love another Vocaloid, hate another Vocaloid, same character, mirror images, etc. There are not many variations of this question left that have not been asked and you do not need to ask at this point any question related to their relationship with each other. Please read the complete page to get all information on this subject.


  • The Answer wiki will not answer any information concerning non-Vocaloid characters such as UTAU or derivatives that does not refer to a Vocaloid link. This is not the UTAU, fanoid, etc Answer wiki - it is the Vocaloid Answers wiki. Please search elsewhere for answers to these questions.
  • Any asked questions that intentionally make attempts to bypass previously answered questions about relationships will receive a {{Warning}} and potential {{Block}} for spamming the wiki.
  • Do note that completely alternating the section based on personal head cannon will be taken as vandalism.
  • Named characters who are not Vocaloids are indicated via italic writing.
  • Attempts will be made to give direct links where possible to wiki pages related to names, if there is no link then there is no known wiki page available currently.
  • Some Vocaloids will appear on more then one list at times since they have several layers to their "relationship".
  • This page focuses only on relationships between Vocaloids, other backstories will be handled by other "Help" pages.

What if the relationship is not on this page?

If the relationship is not mentioned on this page, it is considered "non-canon", this page will only address "canon" relationships between Vocaloids and non-Vocaloid characters that are officially acknowledged.

Note that non-Canon relationships fall in the realm of "personnel interpretations", commonly referred to as "Head canon". These exist because there is not much "canon" information on many of the Vocaloids and fans often fill in the gaps. This includes unofficial pairings with UTAU and OCs (aka "Fanloids" or "derivatives").

This is most notable in songs, wherein two Vocaloids can be in a relationship of any nature be it professional, romantic or family. However, songs have no barring on the Vocaloids themselves and are not considered "canon". Therefore these relationships will not be addressed here. Fans, however, have been largely influenced by these songs. This results in certain Vocaloids being in a relationship of some form, often romantic, being paired with each other when no such relationship exists.

What is a "Relationship"?

A relationship is a direct and deep link or bond between two separate people, items, animals, etc. It can be family, romantic, professional, work, development, etc.

This page is designed to answer all questions related to Vocaloid relationships.

She has mentioned BIG AL, a VOCALOID developed by PowerFX, as being her best friend.

  • Crypton Future Media; Crypton Future Media have confirmed that the Kagamines have no official relationship and are left to fan interpretation. This applies to all of their Vocaloids and is done to prevent limitations on producer creativity.[6][7]
