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

They don't have an official setting.Those of tu who are convinced that Rin and Len are either twins, o only mirror images, tu 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 tu watch Kokoro, o Paper Plane, they are NOT. Again, in Daughter/Servant of Evil, they are.

Many fans see them as twins and other fans 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 enamorados it would just be gross cuz Rin is 9 segundos 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 enamorados etc
And it can be your choice as well
