Yet she’s sincere and kind-hearted and a little romantic. It’s surprising to see a character like this heading up a James Bond style spy action story, but despite her timidness she has the bravery to pull it off. Yumiko is countered with Miss Deep, her special agent partner who can move through solid objects. Miss Deep is everything that Yumiko is not – bold, fearless and cynical. The two spark an unlikely friendship that forms the underlying focus of the action thriller that is Read or Die."
