18+ Secret Dog God Kokoko-chan

Horihone Saizou began serializing his manga "Himutsu Inugami Kokoko-chan" (Secret Dog God Kokoko-chan) in May of 2002 and didn't finish it until November 2006. Fans who have followed and collected the single
chapters as they appeared in such anthologies as "Komoe", "Last Child" and "Kotorikan" will notice that two chapters were significantly altered for the collected paperback (tankoubon) volume. I'm talking about the
chapters "The New Student" and "Lord of the Flies". Both received additional pages and - to some extent - different different endings.
