Ranko Tsukigime, the only child of the underground "Tsukigime Enterprise" is an average high school girl by day and a deadly assassin by night. While taking on a new mission, an enemy organization threatens the lives of Ranko and her friends. This 2D fast-paced side-scrolling action game will draw players deeper into the schoolgirl/assassin's thrilling life, and serves as a video game tie-in to Katsuhiro Otomo's four-part anime compilation film project, SHORT PEACE. POSSESSIONS, GAMBO, A Farewell to Weapons and COMBUSTIBLE are joined by the fifth and final part of the project; Ranko Tsukigime's Longest Day. Players will put their reflexes and quick judgment to the test in fast-paced platforming gameplay that will have them blazing through dangerous, obstacle-ridden environments to flee from an ominous enemy looming close behind.

The game is very short, the cutscenes and gameplay add up to about 3-4 hours. That said it is very crazy, has easy to get used to controls and nice visuals in the cutscenes.
