Male, 5'6, blood type is B. Yamada is pessimistic and has a fear of social interaction. He is very self-critical, worrying about how his creations would appear to others because as an artist, he demands a lot from himself. In spite of his negativity, he has an extremely large passion for arts, to the point where others see it as almost an obsession. He approaches and talks to people who show an interest in his work and is very friendly to them, a great difference to his usual behaviour.
