In Rin's case, despite your established age, you're not sister-like so no one called you that.

Right now there's a lot of Vocaloids here and there being active...

Rin is the second generation continuation of V2 after Miku-nee!!

Soon to be 12 years of history already!!

We're supposed to be great seniors yet don't you think there's too little recognition!!?

That's because you're already in the cutesy group, even if you try to put on an angry look like that...

That's why Rin would first behave as a great older sister of Len so everyone will slowly show respect!

If you had done that from the start, you wouldn't be in the position of the youngest child for 12 years, would you...
