i don't mind koizumi, but i do think its kinda funny seeing her act as if she knows exactly what's going on in shino's situation while at the same time saying shino couldn't possibly understand her family's situation as an outsider. then again she's what, 15 or 16? so i guess that kind of logic is kind of expected. she does at least do a better job of describing her feelings towards her younger sister in this chapter at least instead of just legitimately seeming like she thinks of her younger sister as nothing but a burden like she did before.
