Eight years ago, a gangster sought out Yunosuke Narumi for advice about leaving his crime syndicate and becoming a normal member of society.

"I can't stand life in the gang anymore," he told Narumi, who works for the Osaka Prefectural Police providing advice to yakuza who want out.

However, the gangster's left pinkie had been chopped off. Yakuza are required to cut off their own fingers to settle vendettas or as a price for making a mistake.
