Dead Fic: Threatened to become this until it was revived in 2011.
Schedule Slip: Sadly all too common due to the long chapters and the author's private life. A chapter can take as little as two weeks or as long as four months. The worst was when the story went to be on hold for two whole years from 2009 - 2011.
The way the death penalty is executed in Japan was shown in frightening and realistic detail during Ryoga's fake memory of being on death row.
The cemetary where the Senshi battle for the second Rainbow Crystal was determined by the author to be the foreign section of Aoyama Cemetery, as no other place would fit in the area.
Pachinko culture was explained realistically.
The ruins of Meroe were laid out by a real map and the location of the buried temple determined by the author.
Throw It In!: Happens a lot due to the author only having the basic story outlined, filling it with the details on the go. This of course means that good things get integrated into the main storyline as well.
Updated Re-release: The prologue and first five chapters were written two years before the story got continued. When starting writing again, the chapters were in need of a massive overhaul. Especially Ranma's speech patterns needed fixing, as in the original release he spoke like an idiot.
