Most of the people I know see Nagisa as a mere cute girl who always smiles all the time. Or an outgoing airhead who always fools around.
Man, but really... There's more to her than that!
The other members know that despite her bubbly front she's a serious and hardworking person >> video link
And even though how fluffy she look there's a bit of violence tendency in her, too >> video link
And her arm strength... putting the martial art joke aside, you better not make her angry... >> video link
Have I told you not to make her angry? >> video link
Well, as long as you don't hit these three "Anger Points" >>video link
There's a beast(?) hiding behind that gorgeous smile, y'know.
Oh well, enjoy the many faces of Nagi~
