Inoue launched the Btooom! manga in Shinchosha’s Weekly Comic Bunch magazine in 2009, and then transferred it to Monthly Comic @Bunch in 2011.
The manga ended its serialization in Monthly Comic @Bunch in March 2018, and a different ending ran in Shinchosha’s B Bunch magazine later that year.
Manga creator Junya Inoue posted on Twitter on Wednesday that they will launch a new manga tentatively titled Kaijū Jieitai (Monster Self-Defense Force) this spring.
Crunchyroll streamed the anime as it aired, and Sentai Filmworks released the series on Blu-ray Disc and DVD in 2013.
