Someone is murdering Ayabe's gang members in brutal and unusual ways, and as their numbers dwindle, they begin to get crazy...

A master counterfeiter wants to give up the profession, but Ayabe sends Osamu to take him for herself.

Osamu and Akira are sent to steal a rich man's deposit in a tax-shelter bank. However, they don't know which bank it is, so they have to get that info out of him first.

A mother hires Akira and Osamu to find the cause of death of her daughter, who was found floating dead in a river.

Osamu and Akira are hired by a prominent writer's lover to discover why he has seemingly "changed" into a different personality altogether.

Osamu goes to see if Ayabe has any work for him, but it turns out her operation has been shut down by the police, and he and Akira are evicted. They begin to search for Ayabe to try and get some money from her, but Akira takes ill.
