Shinjuku Swan (新宿スワン) is a 2015 Japanese comedy film directed by Sion Sono based on the manga of the same name by Ken Wakui.

Hideyoshi rescues the fleeing Ageha, a hostess in great debt who has stolen 50,000 yen from a safe, and buys her from her angry employer, putting her to work around the clock under Mr. Ohbayashi, the abusive operator of a massage parlor.

Overcome with guilt, Tatsuhiko stops Ohbayashi from beating Ageha, who views him as the blond Dark Prince from her favorite storybook come to rescue her.

He finds her work in a more reputable establishment and takes her on a date around the area as he asks her questions to make sure that she is doing alright emotionally.

Seki convinces his lover Riko to let herself be scouted by Harlem, where she complains of fatigue and is offered drugs by one of the other girls.

She arranges a meet to purchase more drugs at a bowling alley so that Seki can catch the Harlem scouts who are involved, but Hideyoshi foresees the setup and shows up with several men.

Hideyoshi arrives at that moment with a briefcase full of drugs and Tatsuhiko takes it from him but is attacked by Ohbayashi, whom Ageha stabs and kills.

He finds out that the drugs are coming from Club Gorgeous and Yamashiro sends out all his men to hunt down Hideyoshi to obtain evidence from him.

Tatsuhiko's friend Sakakibara jumped in between them and was stabbed instead, becoming paralyzed, after which Daiki Furuya left school and eventually changed his name to Hideyoshi.

The film ends with Tatsuhiko scouting girls at his normal location when he believes he sees Ageha walking down the street past him.
