Harry x Kurama
First she was Kuronue, then she was wiped clean and reborn Harry, but now she is both.
For she wields Death, and Life and the mystery of them both at her fingertips.
Yu Yu Hakusho cast are all about 2-3 years older than they are in canon.
Harry isn't really introduced to the YYH cast till slight before the dark tournament, and then only to Kurama. She meets the rest of them after the Chapter Black Incident, and helps out with the demon world tournament, not sure if she participates or not.
HP time wise it is after the BoH. Where Harry does and awakens to her inheritance, the power her ancestor Ignotus Peverell wielded, the powers of Death and Life. Along with this some things from her pass life as the demon bat Kuronue return to her.
But these powers are too much for her body to handle and slowly but surely they are killing her even as the grow.
The public catch wind of her growing power and fearing the worst through her into Azkaban, where the dementors whittle away at her remaining strength.
And that is where the Spirit World come in to play. For King Enma and Prince Koenma promised Ignotus Peverell (a man who did them many favors) to help any of his descendants that ended up gaining his powers however they could. When Koenma learns of what has happened to Harry, he immediately calls for Kurama who was a master thief, in the hopes that he would be willing to help a squad (Japanese Aurors and Spirit World 'Officers') in rescuing Harry from this 'death penalty'. He agrees when they tell him all the facts they can, though he does say that he'll want something in return, though at the moment he doesn't know what that would be (Koenma agrees as long as his request/reward is reasonable).
The group is successful in retrieving Harry before she succumbs to he weakened body. A ritual is prepared, one that will take her soul and all its inherited power and strength and put it into a body/vessel that can actually withstand her still growing power/spirit. (A blank body/vessel was already ready, since they had to use something to give Boton a physical body right?!). Once the ritual is completed the vessel will change to suit Harry's soul/spirit/power as it sees best, it could also make the body into what she should have been if she wasn't heaped with a misfortunate life up till that point in time.
It is during this ritual that Kurama senses it (he got to watch), this soul he rescued is the same as his old friend (the one whom he couldn't save), Kuronue, though it has been 'cleaned' and is now 'pure'. But still he would always recognize Kuronue.
After the ritual is completed he surprises Koenma by waiting by Harry's side as she recovers and adapts, when he is asked about this is tells Koenma he has decided what he wants as payment. He wants her. He wants to protect his reborn friend, and this time he will not fail and will not loose her again. (Kuronue was male just to clear that up, and Harry is female, reincarnation can do this).
Koenma, seeing that Kurama means her no harm and really wants to protect her agrees. (For Harry Peverell is basically a princess in the spirit world now due to her inheritance from her ancestor Ignotus, her powers would be of great help to them).
Harry sleeps for a while longer (basically through the entire dark tournament and most of the chapter black stuff, before she awakes). And Kurama is the first thing she sees when she does (he was given special permission to come and visit her whenever he wanted to), and to his surprise she calls him by name. He embraces her in relief and in joy (and some apology), and cannot stop from telling her all that she's missed and how sorry is was and that he is so happy that she is once more beside him. They spend the next little while trading tales and stories about the lives they've been living since they were parted. (Though Harry is still quite weak and can't yet leave her bed).
Her appearance has also changed from what it was (short black hair and bright green eyes with a malnourished body). Now her hair has grown to an outrageous length and one of her eyes is now a purple/lavender shade (like how they looked when she was Kuronue), she no longer looks malnourished, all her scars are gone, though she still is quite short, maybe around Heie's height.
