We're supposed to be great seniors yet don't you think there's too little recognition!!?In Rin's case, despite your established age, you're not sister-like so no one called you that.If you had done that from the start, you wouldn't be in the position of the youngest child for 12 years, would you...That's why Rin would first behave as a great older sister of Len so everyone will slowly show respect!Right now there's a lot of Vocaloids here and there being active...That's because you're already in the cutesy group, even if you try to put on an angry look like that...*angry puff*Soon to be 12 years of history already!!Rin is the second generation continuation of V2 after Miku-nee!!*GLOOOM*Rin wants to be called "Onee-chan" too...!!
