Kabukicho, Shinjuku, the number one entertainment district in Japan. There are professional gigolos who make this sleepless city their base and get what they want, from money and women to desire. They are the "gigolo" gang led by the charismatic Naoki Fushimi. Akira, Yuki, and Ryoma are aiming to become full-fledged gigolos. Akira has a girlfriend named Mariko who is a model for vinyl magazines. But that's not enough for a gigolo. For a gigolo, having sex for free is meaningless. Yuki finds a soapland girl named Misa, and Ryoma finds a woman named Yoko, and they spend a sensual night together. Meanwhile, Akira is taken by Mariko to help with a vinyl magazine shoot. Akira is getting increasingly impatient with his life, which can hardly be called gigolo...

When a Babylonian vampire comes to old Japan, an army of Japanese demons and ghosts gather and battle him.

One of the nuns at Senjuan is Sister Shunko (Michiyo Yasuda). Unlike the usual nun, however, she often goes out to see the world, being of the opinion that nuns should not lead cloistered lives but should see something of modern life. She makes the acquaintance of a young girl named lkuko (Kayo Mikimoto) and saves her from the advances of a gangster named Goro (lchiro Nakatani). In the meantime she turns down several propositions and, in revenge, one of her admirers denounces her to the Mother Superior (Kuniko Miyake). This lady is of liberal views, however, and refuses to do anything about it. Then Shunko is visited by Goro's gang boss who wants lkuko back and says he will blackmail Shunko unless she agrees.
