Sekai Eiyushi

is Pink Lady's 18th single, released on May 21, 1980. At the time of the single's release, the duo returned to Japan after failing to make a mark in the U.S. with their ill-fated variety show. At the same time, rumors started circulating about Pink Lady's disbandment, which was denied by the duo until they made an official announcement in a press conference on September 1.

The single sold 150,000 copies.
