Sentai Filmworks has slid out another licensing announcement for streaming and home video release today with Btoom! The series will get digital distribution soon with a home video release to follow sometime in 2013. The series is based off of the manga by Junya Inoue that began in 2009 and has eight volumes to its name so far. The series is being animated by Madhouse with direction by Kotono Watanabe, with scripts by Yousuke Kuroda (High School of the Dead, Hellsing Ultimate), and character designs by Takahiro Kishida (Puella Magi Madoka Magica, Armored War Goddess).
Shame, this probably would have turned out better if it was picked up by FUNimation.
