Is Len and Rin siblings or....?? Help Please ^^

They don't have an official setting.Those of आप who are convinced that Rin and Len are either twins, या only mirror images, आप are BOTH wrong. EVERY SINGLE VOCALOID plays a different role in each song. In some songs Miku & Kaito are dating, in others they are not; SO ARE THE KAGAMINES RELATED IN SOME VIDEOS. Obviously, in this video, the role they are playing IS twins. Now, if आप watch Kokoro, या Paper Plane, they are NOT. Again, in Daughter/Servant of Evil, they are.

Many प्रशंसकों see them as twins and other प्रशंसकों see them as mirror images.It depends on the song.

They are siblings, seeing as how they're twins.

They are twins.

yes they are twins they only sing as प्रेमी it would just be gross cuz Rin is 9 सेकंड्स older that is why in daughter of evil she is princess/queen

They aren't twins they are mirror images,
It depends on the song if they are twins प्रेमी etc
And it can be your choice as well
