Oh, okay. It seems that I have switched and reversed the nature of the Galaxy Cauldron. Type 5 should be fine then, I think. Although, NEP might be a stretch.
Although, now that I am thinking about it, I don't know about Type 7 for Death Phanthom, because IIRC, Type 7 is only for things like Zombies. People that have died and live on, like souls or in this case Death Phantom as a separated consciousness I don't think it would apply for Type 7. But you would need to more properly discuss this was someone who knows more about this than I.
I don't really care for NEP so it's no big deal.
There are several ghosts characters with Type 7 from my stroll through the wiki so it's not unheard of.
I want to move into Type 4 Acausality so this thread can come to a conclusion:
My main argument for it is that like the descript for Irregular Causality:
Characters with this type of Acausality operate on a different and irregular system of cause and effect than regular causality.
Characters in Sailor moon don't follow a regular causality.
Changes in the past rarely have an effect on the future unless it's very serious things.
Like when the cast were
erased by Galaxia and their Sailor Crystals (special indestructible star seeds that give people their abilities) were stolen,
they appeared unaffected in the future weeks later in later chapters. Sailor Pluto tells Neo Queen Serenity that there are
abnormalities in the past. And that history may be changed. And in later chapters they are
incapicpated some indefinite time after. Chibi-Usa and Neo Queen Serenity were completely unaffected by these changes. Under normal causality, Chibi-Usa would be effected by father dying and Neo Queen Serenity's life would be drastically changed by her husband and allies dying in the past. But it seems to be only having an effect on their relative present.
The other major change that happened was when
Tuxedo Mask fell into the Galaxy Cauldron and
that erased his entire future along with Chibi-Usa. This was only time that causality seemed to behave normally. But the reason isn't so normal. The Galaxy Cauldron is not only the source of everything but the starting and ending point of everything. It would seem that it would be impossible for a starseeds or Sailor Crystals to exist somewhere in time and space as well as inside the Galaxy cauldron at the same time.
We see this in several things, for example,
Death Phantom was destroyed in the future during the second arc, but in the fifth arc,
his star seed is in the Cauldron and Chaos confirms him to be
killed by Sailor Moon. While this battle already happened in the future, it had yet to happen in the present. We also see in things when Chaos says the
Galaxy Cauldron sends seeds out through both space and time and when Chibi-Usa was regenerated with the Lambda power, the Galaxy Cauldron sent her to be
reborn in the future.
Other instances of irregular causality exist all over the manga.
For example, Neo Queen Serenity gives
her past self and the
cast upgrades to the use in the past. Neo Queen Serenity
says that meeting her past self would change history and then decides to
meet her past self anyway. She then gives herself
her own scepter to fight with in the past.
Sailor Moon asking Neo Queen Serenity for
power boosts. Chibi-Usa asking Neo Queen Serenity to give her a way to fight and her
giving her an upgrade. Sailor Pluto
died in the future and was
re-incarnated in the past, making the Sailor Pluto in the past, the future version of the Sailor Pluto in the future. Sailor Pluto had
memories of her past life which technically didn't even happen yet. Black Lady was able to
attack the cast in the
past from the future. Chibi-Usa getting a
vision of Luna, Artemis, Diana dying the moment their death occurs
in the past. And that was the moment that pushed her to return to the past.
The manga seems to treat the future like it's some distant place rather than a different time period. Time passes in the past and the future simultaneously. Causality seems to be independent on the flow of time, the past and future changing each other through cause and effect instead of just the past changing the future.
