Koji Nanjo was a famous rock idol who went through life without caring for anybody, with one exception: When he was in fifth grade, he watched a wild-eyed boy playing soccer. The image of that boy's intensity stayed with him into his adulthood.
Izumi Takuto was a genius soccer player who bore emotional and physical scars from his mother's murder attempt when he was a child. He spent his whole life keeping anybody from getting too close to him.
The story of how these two men met again and fell in love is covered in the OVA Zetsuai 1989. Bronze Zetsuai 1989 is the sequel. When Izumi leaves for soccer training in Italy without saying good-bye, Koji rushes to catch up with him at the airport. But on the way, he has a motorcycle accident that leaves him in a coma. Izumi is the only person who can bring him out of it, but he's not sure if he really wants to...
Cathexis is a collection of five Koji Nanjo music videos based loosely on Bronze, placing Koji and Izumi in all sorts of strange settings.
