This clip starts where Part2 ended. The bill collectors tried to make Ayaka to sign, but she regused it. So they changed their mind. One of the guys thinks to made them to drool, to gather their saliva and sell it. He changes the gag to ring gag, puts glasses in fron of them, and leaves them their.
After while he comes back, Miki talks to him that he will not able to get enough money if he sells saliva. Miki offers him to share her inheritance money. He agrees it and tells Miki to make Ayaka sign it.
Then Ayaka is nose hooked and covered her mouth with duct tape over ring gag.But Miki has another idea that she gets whole of money herself. He finds her breach and ties Miki up again.
