The game is part of the four-part Short Peace film anthology, with Ranko Tsukigime's Longest Day as the fifth and final episode. The title is a high speed side-scrolling action game that tasks players with using special effects to defeat oncoming enemies. Protagonist Ranko smashes through levels taking out opponents, which burst into colorful objects upon defeat.
Ranko Tsukigime's Longest Day was developed in collaboration between Grasshopper Manufacture and Namco Bandai. No More Heroes and Lollipop Chainsaw developer Goichi "Suda 51" Suda wrote the scenario, while Tokyo Jungle director Yohei Kataoka oversaw the game. Other well-known game makers on the project include Fire Emblem: Awakening and No More Heroes illustrator Yusuke Kozaki and Silent Hill composer Akira Yamaoka.
There is currently no information on a western release for Ranko Tsukigime's Longest Day. Short Peace was released in Japan last summer, and its short Tsukumo — under the name "Possessions" — has been nominated for Best Animated Short for the 86th Academy Awards.
Namco Bandai registered a domain name for the title in Europe last fall, but there is no word on a North American version.
