The 22nd compiled book volume of Junya Inoue's Btooom! manga shipped on Saturday and revealed that the series will enter its final arc in the next volume. The 23rd volume is slated to ship in Japan in May.

Shinchosha's Monthly Comic Bunch magazine had announced in March 2014 that manga was entering its final arc in the next issue that April.

The story centers around Sakamoto, a NEET (Not in Education, Employment, or Training) young man and a top-ranked player in the online combat game Btooom! One day, he wakes up on a tropical island without remembering how he got there. He sees a figure in the distance and asks for help. However, the figure responds by throwing something at Ryūta — a "BIM" bomb.

Inoue launched the series in Shinchosha's Weekly Comic Bunch magazine in 2009, and then transferred it to Monthly Comic Bunch in 2011. Yen Press is publishing the manga in English. The company released the 15th compiled volume on November 22.

Kotono Watanabe directed a 12-episode anime adaptation of the series in 2012. Crunchyroll streamed the anime as it aired, and Sentai Filmworks released the series on Blu-ray and DVD in 2013.

The manga is also inspiring a multiplayer smartphone game from developer Asobimo.
