–Netsuki, about Border's image.
Eizō is a thin, middle-aged man of frail appearance. He has chin-length hair and a big, arched nose, along with the usual relaxed or puzzled expression. Being a high-ranking member of Border, he often wears the same navy-colored suit.
Eizō is a usually a calm person, but gets easily nervous. He is shown to be very fearful and to worry about his image.
- His surname is an inversion of kitsune (狐?), which means "fox" in Japanese. In Japanese folklore, kitsune are rivals of tanuki (狸?), the inversion of Kinuta's surname.
- He likes black tea, horses, gardening, and collecting Border's merchandise.
- Kageura landed an uppercut on him resulting to the latter's demotion to B-rank.
