Aoi Morikawa, Shūhei Uesugi, Shiori Doi, SUMIRE join cast of film based on Kyoko Okazaki manga

The official website for the live-action film adaptation of Kyoko Okazaki's River's Edge manga revealed four additional cast members and film's February 2018 opening on Wednesday.

The new cast members include (clockwise from upper left):

Aoi Morikawa as Kanna Tajima, a classmate of Yamada's who seems unconditionally kind to him Shūhei Uesugi as Kannonzaki, Haruna's boyfriend who bullies Yamada Shiori Doi as Rumi Koyama, Haruna's friend who gets pregnant but doesn't know who the father is SUMIRE as Kozue Yoshikawa, a model with an eating disorder who grows closer to Haruna and Yamada

The previously announced cast includes:

Fumi Nikaidō (Himizu, Inuyashiki, Wolf Girl & Black Prince) as Haruna Wakagusa

Ryō Yoshizawa (Kamen Rider Fourze, Gintama, Tomodachi Game) as Ichirō Yamada

Isao Yukisada (Crying Out Love, In the Center of the World) is directing the film.

The manga centers Haruna Wakagusa, a high school girl living in a town during the 1990s, and Ichirō Yamada, a bullied gay teen. Haruna gets to know Ichirō after she helps Ichirō while he was being bullied by Kannonzaki, Haruna's ex-boyfriend. While together, they see a dead body by the riverbank that becomes their shared secret.

Okazaki launched the manga in Takarajimasha's CUTiE magazine in 1993, and ended it in 1994. Takarajimasha published the one compiled book volume of the manga in 2000, and again in a hardcover edition in 2008. Takarajimashi re-issued the manga again in 2015. All three versions have different covers (seen right is the 2015 reprint).

Another manga by Okazaki, Helter Skelter, also inspired a live-action film in 2012.
