Ironcat

Sakura Mumoguri is an innocent, bookish virgin, who just wants to lead a normal life. It's not possible, though, for she is also Iron Cat-virgin of steel. And "incidents" keep happening, usually in the form of Iron Cat's enemies who show up to wreak havoc in her life. Meanwhile, she must also deal with a love-struck photographer determined to win her affections, heedless of the fact that she thinks he's a pervert. Source: Studio Ironcat
