Although he looks pretty carefree, he takes his job seriously as Seishuu's art dealer. He's a nice guy who helps out Seishuu and sometimes even gets worried for him. However, he admits he considers Seishuu as someone he makes his money from first before considering him a friend. He can also be strict as he told Seishuu he wouldn't give Seishuu sympathy when he punched the museum curator when he said harsh words about Seishuu's work since the curator he punched was an old man using a cane. He also seems to have a temper which becomes more ferocious and volatile when he is drunk. He can also be shrewd as shown through his negotiation with Naru to have her show him and Kosuke where Seishuu was and by his use of Kosuke as a rival for Seishuu to motivate him to get better at calligraphy. He is an insightful friend to Seishuu as he understands that coming to the island will be good for him as it will help him search for his purpose and style as a calligrapher.
