Divine Child of the Inferno
A Ranma, Sailor Moon, Ah! My Goddess! cross idea.
Safron gets reborn as Ranma-chan's Son. I'm just going to say this is AU because I don't know if I will keep anyone IC enough to satisfy some purists.
The end of the Battle with Saffron appears to go the same way it does in the Canon Manga except Safron doesn't hatch. Saffron's life made him stray from the Divine path and almost turned him into a Demon. It left it's mark on him. Had he killed Ranma he would have been a Second Class Unlimited Demon under Hild. So, to nearly every Demon hunter in Tokyo, his presence until his redemption is seen as just another Demon attack.
In this Fic Saffron was a God of Fire and Rebirth, Third Class, Limited. But as the Kami of an Element his existence lends power to that element. His Rebirth, strange as it may sound, is a threat to Crystal Tokyo because of that. For the Great Freeze to occur Saffron must die in his punishment and education as a mortal. While that makes the Senshi out to be the bad guys, in the initial Time Line they weren't the ones to kill him, and Pluto never did find out the cause for the ice.
What Pluto saw as the two majority groups of the Future were Armageddon Vs Crystal Tokyo. She missed the point of divergence or the fact that Saffron was the unbalancing element that causes Armageddon in those time lines. What she saw is the world may have problems including Armageddon popping up in some time lines around the same time Crystal Tokyo would be founded.
Sadly that has caused Pluto to think the world has the options of dieing in conflict or Crystal Tokyo without even noticing how much healthier the world is in the Non-Crystal Tokyo time lines. Or seeing that most of those conflict time lines were missing the Key Event of Ranma defeating Saffron at Mt Phoenix.
The Destruction of Saffron (True Death not the usual one he can be reborn from) causes all Fire element energies in the world to diminish. Meaning you can still be burnt by putting your hand in a fire but it takes twice as long. The true cause of the Great freeze happens along those lines. The Magma of the world remains just as fluid but with the loss of power in fire it just isn't as hot anymore and can't keep the surface from freezing at night. Electricity isn't as potent and generating it takes 4 fold more resources than it use to so that it ends up with the same results.
Ranma isn't locked after the battle or anything and in this fic Pregnant curse victims can go a little while changing before they lock. In the Failed Wedding Ranma gets bruises on his face that one week later, when she locks, resolve into cartoon 2 tip candle flame shape Goddess markings. About the same time that happens morning sickness kicks in. She is granted Saffron's License of Third Class Limited But because of her life she has 3 domains. Saffron's 2 along with Balance. Be it literally the balance needed in Martial Arts or spiritual balance of Yin and Yang. The greater her personal balance is the stronger her Divine powers can manifest. Like the Terminator plot at first Ranma will be seen as the Threat to Crystal Tokyo because of the child she will bear.
These ideas are always clearer before I fully wake up. I actually watched about a Ranma Episode worth of time from this plot in my minds eye before getting up this morning and I just can't seem to get my mind to slow down enough to type it out.
Beldandy with Holy Bell were sent to the Phoenix to explain to them why Saffron isn't reborn from his egg before their worries of their god being stillborn after his battle drive them to a reckless war against his killer. Strangely enough if that hadn't been averted they would have killed Mortal Saffron, before birth, themselves. It's not an easy explanation but in the end Kima is made to take the role of Leadership for the Phoenix so that the Council who created Saffrons dark path to demonhood no longer have authority and maybe their people can grow while they are without their god.
In the Aftermath of the Failed Wedding. After Kasumi finally manages to pry herself out of her crying and frightened fathers arms, he feared that the battle in the dojo on so many fronts would take the life of his "Little Girl" and clung onto her as if his own life depended on it. She finds Ranma battered and bruised up on the roof. It takes a bit for them to work through what happened in the day but by the end it's made clear that at least Kasumi didn't abandon him to that wreckage. Akane stormed off to her room traumatized thinking that this would happen again if she ever tries to be with Ranma and it's too much for her. Nabiki is unconscious having been caught in the wind from one of the explosives and knocked out. She doesn't even know the extent of the damages her little profit scheme created. Nodoka made Genma bring Nabiki to her room and then dragged him home for a long talk to find out just why so many girls (Some she remembers from wrecking her house before) appear to have claim on her son. Mistresses are one thing Jealous and Dangerous Rivals that could claim Blood Feud for dishonor are another.
This all boils down to my idea that Ranma may not have broken him but she did end Saffron's life and seeing that he's Honorable enough to help prevent a dark destiny for the god of the Phoenix people the responsibility to bring him up right falls to her. Not that Hell is likely to give up on such a promising near success to their own sides power.
I was reading Ah! My Ranma 1/2! before I went to bed and woke up with this idea. Sadly some of the other details for it have already disappeared because of my waking up. Any suggestions for how it could go or some resources Hell might contribute to the mix could be helpful.
