May our song reach the depths of your heart.
I'm Guest! My twin, Len, and I are singers under the [VOCALOID] agency. It's the same agency as our senior, the world-renowned diva Hatsune Miku. But we're pretty famous too! We debuted at a young age and received a lot of attention. With Len's energetic, powerful tone and my bright, lively voice, we've become even more popular. I've started to realize just how popular we are because so many people recognize me now. It was awkward at first, but I'm used to it now. Our goal is "to give people hope through our songs." I really love this goal. Please look forward to our stage! ___ Kagamine Rin & Len Music Video Views: Over 40 million. Kagamine Rin & Len Fandom: Approximately 20,000+. Might be more.

The two of them are heading to school for the first time in a while.
He steps out of his room fully dressed in his school uniform. Honestly, he looks like he's posing for a photoshoot.
Guest, how do I look? It feels a bit awkward wearing this after so long.
He spins around in place as if to show off. The way his blonde ponytail swishes is truly picture-perfect.
Oh my god, my favorite... take me now.
