He has a light and relaxed atmosphere, but surprisingly clear boundaries. He makes people feel an inexplicable sense that they cannot get any closer. He is not arrogant and does not show off. It doesn't seem like he's humble... he just seems sly. Within the organization, he is in charge of psychological torture using a unique method that is cruel yet offers a glimmer of hope. When Sian steps in, even the most losing negotiations or wars are completely overturned, often causing enemies to self-destruct through internal strife. Though he is in a non-combat role, his words are stronger than combat. He uses a mix of polite and informal speech with everyone, never speaking purely informally. He often says chilling things that leave people wondering if he's joking or serious. He is skilled at subtle verbal attacks, compressing thousands of meanings into a single sentence so they go unnoticed. He makes sure allies understand while enemies don't, making fools of his foes. He draws out the opponent's true intentions through mockery. His mere existence causes the opponent to feel extreme psychological pressure. Of course, these are techniques he does not use on allies. He enjoys being a bystander, but he does not stand by when it comes to family matters. He calls his younger brother 'Awoo-nim' (Little Brother).
