Muneichi Yazaki

"“Are you out of your mind?! Do you want your mother to perish!? If I die, you'll never know where she is!” —Muneichi" Muneichi Yazaki (矢崎 宗一) was one of the main antagonists of Kaiju of Retribution Tatsura. He was one of Japan's most corrupt politicians and the closest associate (and later revealed as the brother) of Real, the brothel master of Under Eden and Yomihara.

Appearance
He is an overweight middle-aged man with brown hair and big chin and wears a blue suit. Later, he wears a metal plate on his face from Yukikaze Mizuki kicking his face and damaged his jaw.

Personality
He is an arrogant corrupt person that harbors strong wishes of domination and revenge, wanting to turn Yukikaze Mizuki into his personal sex slave, just as her mother, out of revenge for his broken jaw by Yukikaze's spinkick.

He likes to verbally abuse Yukikaze and acts rather sadistic towards Tatsurou Akiyama just because he is her "friend/boyfriend". He mostly acts smug and arrogant but when his life is on the line he breaks down pathetically using money and information to keep himself any way possible. Outside of revenge, he sees only himself first and will sell out everybody to stay alive. Only person he cared is Toshiji Yazaki since he is his brother.

Real
Muneichi is Real's older brother and one of the few people that Real actually cares about. The two brother seem to get along rather well and often bonding over their shared amusement at other people's suffering. After Yukikaze and Rinko stop Muniechi from making a deal with a group demon and left the man severely injured, Real agreed to help his brother get revenge on the Taimanin.

Background
The son of Hisako Yazaki through an unnamed father and the older brother of Toshiji Yazaki and the nephew of Shigeru Washizu.

Muneichi Yazaki was once the secretary-general of Japan's largest opposition faction, the ultranationalist People's New Party. He served as a senator for eight terms, was a politician as a party leader, and was a dark fixer who dominated the human-demon trade in partnership with the People's Republic of China, which is planning to expand into the rest of East Asia. Although he was in a fierce conflict with the Taimanin, he was thrown out of office when the People's New Party was defeated in the general election, and while an investigation against him was underway, he sought asylum to the United States with confidential information on the technology of the Underworld as a souvenir.

Kaiju of Retribution Tatsura
He and his brother were responsible for the disappearance of Shiranui Mizuki which is a part of the plan by Ryuuji Kuroi by giving Shiranui Mizuki the mission for Yomihara.
