Real name:
津久井 道雄 Tsukui Michio

A participant in the 12th Juuni Taisen burdened with the title of the ‘dog’ from the Chinese Zodiac.

Does not use weapons on principle; his fighting style involves biting with his teeth. His fangs, which can crush anything, are referred to out of fear as [Kyoukenbyou]. In his private life, he's picked up calligraphy. At first, he could not understand what he had gotten himself into. Nevertheless, he didn't lose heart and continued to write, making his critics shut up with only his sublime, perfected brushstrokes.
Kyoukenbyou: 狂犬鋲 (mad dog rivets), which is a homophone of 狂犬病 (rabies).
