The second season is officially set to debut in Japan on October 1, with Megumi Han (Reoko in BBK/BRNK, Gon in Hunter x Hunter) on the opening theme and Mikako Komatsu (Shizuru in BBK/BRNK, Asako in Ushio and Tora) on the ending.
Around this time last month the official website for Bubuki/Buranki: Hoshi no Kyojin (BBK/BRNK: The Giant of the Star) revealed an October 2016 premiere, and that has since been narrowed down.
According to the site’s news post, the singles for both will launch in Japan on November 30.
