Scaring face of Mio

A screenshot from K-ON episode 4. Mio is really MOE when she's scaring something scary or ghost.
Mio Akiyama from anime series K-ON.
At the first time I saw K-ON, she looks like Yomi from Ga-rei Zero, I think she must be a cool character but not she's moe and easy to be scared when heard something scary ^^
