Okino (沖野) is the manager of Bar CALM where Oryo (Ryunosuke Katagiri) used to work in Hazama. The previous manager had an understanding of devils and even ran the bar as a designated NPO and equal-opportunity employer of red-eyes. However, Okino has a strong prejudice against devils.
Okino is a short and overweight short man with several warts on his face. He is also bald and has big green eyes with small pupils. He is often seen wearing a formal businesses suit.
Okino harbors a deep hatred against devils, so much that he went as far as killing one of his innocent employees. He was very aggressive and determined to make Oryo look like the culprit, though it was quite obvious that he was the one who was guilty.
In an attempt to frame Oryo, Okino plotted to murder one of his employees, Minami. He used a knife to cause massive blood loss to pass it off as a vampire murder, but the autopsy revealed the truth and he got arrested.
