PMK had problems becuse he was based on two manga
Shinsengumi peace maker imon, and Peace maker kuragone.
the first one described all that happened until the iykidaya house incident, and the second was all which happened later.
the supernatrual stuff belong after, and the guy pulling the strings was supposed to be suzu, but in the anime, they replaced the crazy mad suzu with some fag, resulting in a faggy plot.
