Annoying, yet awesome

Rin Kagamine, a 15 year-old going to high-school (No certain name) with the most DREADFUL people! But when a strange gang shows up, Rin is, once again, terrified of the world. Yet, the most annoying trio, Len,Rei, and Rinto all work together to see what's up with Rin, no matter the costs, or what she thinks! I'LL DIE BEFORE I WRITE A TWINCEST, SO DON'T EVEN! (Mild language! ! !)
