Great Teacher Onizuka
Although "Kowarekake no Orgel" was self-published, it featured a somewhat notable production cast: it was directed by Keiichiro Kawaguchi, who was also involved in the production of "Great Teacher Onizuka" and "Hayate the Combat Butler", and featured voice acting by professional voice actors Tetsuya Kakihara (Keiichirō) and Masumi Asano (Flower). The OVA also featured screenplay by Shinichi Inotsume and original character design by POP, which was adapted by Kōhaka Nishio.
