It's an early and surprisingly good-natured Daisuke Yamanouchi movie. No one gets killed or tortured. Katase Nanami (played by Miyabi Yoshimoto) goes from employer to employer, doing good deeds and solving problems with sex. This could have become a TV series. An softcore X-rated one, admittedly, but a heartwarming one about a girl who improves people's lives.
The film's a mini-anthology of two half-hour episodes:
1. ELDERLY DAD AND PROBLEM DAUGHTER
Dad's a gentle old soul. His daughter, Miyuki, calls him a sleazebag, but that's all in the past now. The only physical service he requests from Nanami is massage for his bad back. However, he's worried about his daughter and her relationships. "She shares my blood. I did stupid things when I was young. Prostitutes, debt... Miyuki sold her body for her boyfriend."
Dad's correct. We see the boyfriend pestering Miyuki to go out to work on his behalf again. He provides a time and a location ("the usual hotel"). Nanami fixes this problem with a double prostitution gambit, sending Miyuki a text to make her walk in at exactly the wrong moment. The boyfriend explains that Nanami said she'd give him 50,000 yen if he shagged her. This is true, but hardly counts as an excuse. Result: Miyuki dumps the loser. Problem solved! (Nanami had fun in the process and it seems that sex even helped Dad's bad back.)
2. ABUSIVE HUSBAND AND SUBMISSIVE WIFE
The husband's a miseryguts with no table manners who'll fire you if you: (a) make anything except curry for dinner, (b) get raped by him and might tell the wife. Meanwhile, his wife's practically a zombie. After her husband's gone out to work, though, she comes alive and requests lesbian cunnilingus. Call me crazy, but I think Nanami's about to become another break-up catalyst.
OVERALL
I'm surprised Daisuke Yamanouchi didn't turn this into a series. It has happy endings, it's nice and one assumes that Nanami will continue going from employer to employer. She enjoys it, she's making money and she helps people. What more could you want? This is a cheap, sleazy and fairly unsophisticated film, but it works pretty well.
