Namco × Capcom is a action RPG/tactical RPG hybrid developed by Monolith Soft, featuring characters from games produced by companies Namco and Capcom.

The year is 20XX (sometime in the twenty-first century), and the game is driven by the characters Arisu Reiji and Xiaomu (original characters created specifically for this game). The two of them work for a special unit called Shinra and they are tasked with investigating spirit and otherworldly disturbances. They are initially investigating a strange "sleeping sickness" in the Shibuya area of Japan, when it becomes apparent that something much larger is at stake. Characters, both good and evil, from other times and other worlds begin appearing in Japan in the year 20XX.
