Manga Action
The manga was serialized in Futabasha's "Manga Action" and the 63 chapters were compiled into 7 volumes from February 28, 2009 to June 28, 2011. The defunct American publisher JManga licensed the manga and released the first volume in August 2011. The name of the manga is a reference to Kazuo Umezu's "The Drifting Classroom", which it is a retelling of. The manga has also been published in Spain by Milky Way Ediciones.
