They're technically mirrors of each other, but they're depicted as twins.
Their "family name" means reflection in a mirror. Specifically "Mirror-Sound", and their given names Len and Ren mean left and right. http://en.wikipedia.org/wiki/Vocaloid
Don't take it so seriously now, mi ha ru.
Huh? What -_-;? I was just saying that it's not a trap >_>.
I know. Just as joke, no need to fret now.
rofl, makes sense... since the show appears to be music based.
It's not a show either. It's a "singing synthesizer application software developed by the Yamaha Corporation that enables users to synthesize singing by just typing in lyrics and melody." In short, it's a program that lets you make your own songs. There is a manga, but I haven't read it.
