I like long-haired Rin and all but where did all that hair come from?

If you followed the series up until now, you will know that it occurs several years later, when they have kids. Thus long-haired Rin.

kaito kinda still look the same tho

Rin, Len, Kaito, Miku are all about the same age, and Mrs. Hatsune and Mrs. Kagamine and Luka are all older.

That's actually supposed to be Rin and Len's mom. Not Rin herself.

wonder if they deserve separate tags
