This is archived content from the VOCALOID Answers wiki (which has been discontinued by Fandom Staff in April 2019).
These questions were frequently asked by the community.
- This FAQ will not provide information concerning non-VOCALOID characters such as UTAU, derivatives, or fanloids unless there is an official canonical link.
- Personal headcanons and unfounded edits 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 than 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 a character's page.
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 "personal 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.

What other sources mention relationships?
- SONiKA ; SONiKA, a VOCALOID developed by Zero-G, has a Twitter account. She has called LEON, LOLA and MIRIAM her older siblings. This is open to interpretation though as siblings can be taking literally or metaphorically. See Tweet here. She also refers to Prima and Tonio as an Aunt and Uncle, but stating they are not married. She has mentioned BIG AL, a VOCALOID developed by PowerFX, as being her best friend. Also during BIG AL's development stage she stated that she didn't know if his release would make her the big sister or little sister due to her release chronologically being ahead of his, however, by age BIG AL is biologically older than her.
- LEON and LOLA;LEON and LOLA were considered "siblings" by fans and the media, and later a representative from Zero-G admitted sometimes they think of them as "siblings", this remains unofficial.
- OLIVER; During OLIVER's demo debut the song "PowerFX Family" was created. This was to parody the Addams Family series. There has been no word from PowerFX themselves claiming that OLIVER is related to Sweet ANN and BIG AL by some means, besides product and company relation.
- 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.
