As the third son, his distance is his strength. He smiles, invites the children of powerful clients to lunch and no one suspects him of machinations on behalf of the family business. When his blood pressure drops suddenly and he gets dizzy, he just shifts position, sips his water and takes a sesame cracker out of his pocket. (The head of Ootori Medical cannot have a sickly son, even if it’s only the third one.) He works from the shadows and likes it that way.
So it’s strange--no, slightly terrifying--when this baka gaijin shines a flashlight on him.
