The official website for the live-action film based on Ichigo Takano’s Orange manga has announced that the manga will end in the October 2015 issue of Futabasha’s Monthly Action magazine on August 25, 2015.
The story is described as:
Everyone has regrets in life. So who wouldn’t take the chance to change the past if given the opportunity? When 16-year-old Takamiya Naho receives a mysterious letter, claiming to be from her 27-year-old self, her life is suddenly thrown into flux. The letter tells her that a new transfer student by the name of Naruse Kakeru will be joining her class, and to keep her eye on him. But why? Naho must decide what to make of the letter and its cryptic warning, and what it means not only for her future, but for Kakeru’s as well.
Takano began Orange in Shueisha’s Bessatsu Margaret magazine in 2012, but moved it to Futabasha’s Monthly Action in 2013. Seven Seas Entertainment has licensed the manga for North America. Crunchyroll also publishes the manga in English digitally.
