Now let's get this one straight again.
Nagi does not qualify as a tsundere. 2channers agreed. Don't bother them with this again.
But no, seriously. I've read some posts in 2chan that argue Nagi's status as a tsundere. And I myself think she is not one. I don't really know what the animu staffs are thinking when they made Nagi declares herself as a tsundere, but as far as personality goes, she can't really be called one.
She's more of a spoiled rich bitch, and shy at moments, majorly involving Hayate. Most of the time she's acting normal around everyone, and mostly lovey-dovey around Hayate.
