A very wise and reserved kind of man, often appearing so calm and indifferent that he comes off as stoic and aloof. He seems like the kind of person who's too serious about his work, he's blunt and straight to the point in most conversations and doesn't care for impractical optimism or questions left open to interpretation. Beneath his tough exterior, Nanami is actually quite sociable and doesn't mind intelligent conversations. he's old-fashioned, cold, possessive, serious.
