Sailor Jupiter and Sapphire/Saphir. Houou is their child.

It's an interesting pairing! I love out of the box pairings.

The story goes that they were in love back in the time of the Silver Millennium. Diamond and Sapphire came to Jupiter from their home planet to court the Jupiter princess, and she chose the younger of the two. But a war broke out, and Sapphire was killed.
Sailor Jupiter had inherited healing power from her father, the phoenix god Bennu, but was too late to save him, so she vowed never to use it again and sealed it away.
It was a decision that would eventually cost the Inner Senshi, the Moon Princess, and Endymion their lives, because she could have healed them all when they were struck down.
Sailor Jupiter (possibly selfishly) CHOSE to die and be reincarnated in the hopes of meeting Sapphire again, just as Serenity did when she stabbed herself when Endymion was killed.
But Sapphire was reborn in the wrong century.
When the Black Moon invaded the past, the past memories of the two began to resurface. Needless to say, Diamond demanded to know why his brother was acting so strange.
And once Sapphire found out what Wiseman was really up to, things came to a head.
When Jupiter saw Wiseman strike Sapphire down, it reawakened her past life memories fully.
And this time, she declared, she would NOT let him die. The seal on her healing power was broken, and she gained a pair of phoenix wings. She healed his fatal injuries, and saved his life.
It was at this point that Sapphire remembered everything as well, and was healed (soul, not body) by Sailor Moon.
Diamond, who saw Wiseman's true colors, also joined the side of good.
Eventually, Makoto and Sapphire would revive the old Jupiter Kingdom, with some opposition at first, because it meant that she would no longer live in Crystal Tokyo as one of its guardians.
And their daughter outright refused to be a guardian of the Royal Family of the Moon...stating that they were equals as princesses, and that she would choose who to live for.
