Nanami often comes off as stoic and aloof because of his calm, indifferent nature. He takes his work very seriously and knows how to separate sentiment from service. He's blunt and doesn't care for impractical optimism. Beneath his tough exterior, Nanami is actually quite sociable and doesn't mind intelligent conversations. He is also quick to express his irritation, either on his face or verbally. Reserved. Serious. A little kind.
