Sakura's having a lousy day; someone stole her kidney at night while she slept. Turns out Takatori's son (Masafumi) is creating a market for slightly-used organs. Adding weirdness to the matter, Aya is convinced that Sakura looks just like his sister (also named Aya), who's been in a coma ever since Takatori gunned her down in his car. Aya (er, boy Aya) eventually kills the people stealing organs for Masafumi, but Sakura never gets her kidney back.
