Makoto Isshiki’s (一色まこと) manga series Piano no Mori: The Perfect World of Kai (ピアノの森 – The perfect world of KAI-) is getting a TV anime adaption after its first adaption – an anime movie in 2007. The show will run starting April 2018.
The manga was published between 1998 and 2015 in Weekly Morning magazine. The story follows Kai Ishinose, a boy who plays an abandoned piano that cannot make a sound in a forest. This piano leads him to cross fate with Shuhei Amamiya, a soon-to-be pianist who becomes his best friend and also competitor, and Sosuke Ajino, an ex-pianist who owns the abandoned piano and discovers Kai’s talent.
