Harry Potter: Neko's Mate

**Harry Potter: Neko's Mate** is a non-crossover fanfiction by Vance McGill (formerly known as Fury Serenity) available at Fanfiction.net, and also to logged-in users at AO3. As of Nov 2021, it has reached about 220 000 words; it is officially **on temporary hiatus** but the author intends to "make sure there isn't a long delay in between chapters". Most of the story was written in 2016 with one chapter added in 2017 and another in 2021. It is rated **Explicit**, there are several **AU** elements beside the existence of cat girls referenced in the title, and there is considerable **bashing** of Dumbledore as well as of Ron and Molly.

**Note**: This story contains descriptions of mutually consensual sex between underage characters (12+), as well as twin sibling incest.

## AU elements

* Harry Potter is a metamorphmagus
* James Potter is the son of Charlus Potter and Dorea Black, rather than the canonical Fleamont and Euphemia Potter; Harry's parselmouth ability is thought to have come from the Black side.
* Gabrielle Delacour is just a few days younger than Harry, rather than 5-6 years.
* Harry is a Natural Occlumens – although this is blocked by his magical bindings, so it could be argued that it is merely a different interpretation of canon

## Plot summary

Hermione's mishap with polyjuice potion in second year had rather dramatic results: she is permanently turned into a Neko, or catgirl! She has cat-like ears and eyes, a tail and fur, plus several less obvious features. Despite this, Harry asks to be her boyfriend, and she agrees. Madam Pomfrey explains that, like all felines, she will go into heat once a month, during which time Harry will need to... satisfy her urges. Further, for Harry to be with anybody else – which he might in fact have to, due to being the heir to at least one important House – he will need her approval.

Meanwhile, Harry's hair starts changing colour when he experiences strong emotions, a trait typical of a metamorphmagus. As she examines him, Madam Pomfrey notices that the bindings put on his magical core when he was one, to keep him from doing accidental magic, are still there. He only has access to a quarter of his full power – which will likely be considerable, given how strong he has been even while bound. She starts the process of removing at least some of the bindings, but explains that it cannot be done all at once or he might be overwhelmed. However, she really ought to have discovered this sooner... Using a flushing draught, she realizes that Dumbledore has been using compulsion and loyalty draughts on her for the last year and a half.

The next morning, Harry awakes to find his body has changed: he now looks female! Madam Pomfrey explains that as a metamorphmagus, he wasn't technically born a boy but rather with the ability to take on either sex. She helps him return to his normal form, but comments on how a form like this will let him move around without being noticed as the Boy-Who-Lived. Harry and Hermione take flushing draughts to see if they too have been compelled and/or obliviated, and Harry remembers turning into a girl when he was younger. The first time it happened, only aunt Petunia was home and she was actually quite accepting of this; Lily had warned her, and also named the "girl side" Rose Lily Potter. Dumbledore obliviated them, but Rose returned on her own several times, including one where she met Hermione. Dumbledore also orchestrated the whole friendship with Ron, from their first meeting to the troll incident.

When they are released from the hospital wing, Harry and Hermione move into private quarters and Sasha, one of McGonagall's house-elves, is assigned to help them – including a daily sweep for eavesdropping and spying enchantments. When they tell McGonagall about the compulsions and obliviations, it turns out he used them on her as well.

McGonagall has a discussion with Ron, and his father, about his involvement in the affair and Ron confesses. She asks Arthur to bring him home for the remainder of the Christmas break, and suggests that he tries to make a deal with the DMLE once their investigation starts: if Molly and Ron testify against Dumbledore their own parts in his crimes might be overlooked. Arthur agrees.

McGonagall has hired Tonks to teach Harry about his abilities as a metamorphmagus, but before she arrives there is time to teach him some important things about his family history and wizarding society at large: polygamy is legal in Magical Britain, and is more or less expected for those who are heirs to more than one House – as Harry is likely to be. In fact, beside his mother his father was under contract to marry the sister of Lord Castor Greengrass, with whose family the Potters were allied, and would no doubt have done so had she not been murdered. Since he didn't, her niece Daphne Greengrass has likely inherited the contract.

Hermione's parents react badly to the news of her new status, suggesting surgery to remove the tail and ears as well as a withdrawal from Hogwarts, returning her to the muggle world. When they cannot be talked out of it, McGonagall knows only a single way around it: if Harry, as she suspects, gains his emancipation and a lordship, he can take Hermione as his vassal.

The three of them (and Tonks) visit Gringotts and meet Ragnok the Sixth, Account Manager and Vault Keeper of the Ancient and Most Noble House of Potter, who lets Harry take an Inheritance and Blood Test and presents him with his parents' will – and no less than three betrothal contracts! Beside Daphne, he is betrothed to Padma Patil and Gabrielle Delacour (who is just a few days younger than he). The inheritance test shows him to be the heir to not just one but two lordships – Houses Potter and Peverell – so he and Hermione perform the Vassal Ritual. Beyond the lordships, the will gives him access to a large fortune – a quick estimate suggests yearly revenues of at least two million galleons – as well as the Potter cottage in Godric's Hollow, the Potter Manor in Northampton, the Chateaux Potter in Nice, France, and a beach vacation house in La Rochelle, France. It also reveals a list of suggested guardians he should have lived with, headed by Sirius Black – and an explicit note that he should *not* be placed with the Dursleys. What truly shocks McGonagall and Tonks, however, is the note that Sirius is Harrys godfather "per the Godfather Ritual", which means that he could not have betrayed the Potters and survived long enough to be put into Azkaban...

After a visit to the Potter family vault – much larger than the trust vault Harry saw with Hagrid – Tonks gets to meet Rose and they go shopping for clothes at Madame Vesti's Witchwear, a clothes shop run by a fellow metamorphmagus.

McGonagall contacts Amelia Bones, head of the DMLE, and tells her about Dumbldore's use of compulsion and obliviation, as well as the whole Chamber of Secrets business that he had kept hidden and the fact that he let Sirius go to prison while knowing he was innocent. While Madam Bones starts her investigation, Hermione goes into heat.

Dumbledore is arrested, and his wand is taken. Harry and Hermione agree to give magically signed written testimony (because Hermione is not yet prepared to show her new form in public). When Harry shows the Peverell signet ring, the Elder Wand reacts to it and accepts him as its true master. Harry hides it in his school trunk until he has a chance to put it in his Gringotts vault.

After interviewing Moaning Myrtle, Moody and Head of the Unspeakables Algernon Croaker have no problem finding the entrance to the Chamber – even if they can't open it – and they decide to return the next day with a fully prepared team of Unspeakables; they will also bring aurors and people from the Beast Division to cull the acromantula colony in the Forbidden Forest. Severus Snape, upon hearing that Dumbledore is arrested, is happy to confess his parts in the Headmaster's many crimes, including coating a certain bathroom in troll-luring potion; Azkaban, he thinks, is probably the safest place to be once Dumbledore has used his political influence to dismiss his own case and starts looking for the people who gave evidence against him.

The petrified Colin Creevey and Justin Finch-Fletchley are revived with Mandrake Draught brought by the Unspeakables. Madam Bones speaks to Minister Fudge, who agrees to arrange a trial before the full Wizengamot – for Dumbledore and Snape, but also for Sirius. The latter is to be brought to a holding cell on level ten, and checked over by healers from St Mungo's to make sure he is sane enough to stand trial. McGonagall tells the rest of the teachers, and names Aurora Sinistra the new Head of House for Slytherin.

On the day of trials, Sirius is cleared of all charges, but so is Dumbledore, because Snape takes the fall for him and claims that he made the compulsion and loyalty draughts keyed to Dumbledore not on the former headmaster's order but to frame him; *his* sentence ends up as 50 years in Azkaban. Still, Dumbledore has lost his three main positions – Chief Warlock, Supreme Mugwump and Headmaster – and the Hogwarts Board of Governors, after interviewing them both, vote to not take him back but instead give the post to McGonagall.

McGonagall hires Andromeda Tonks as the new Potions professor, and Remus Lupin as new professor of Tranfiguration – and, as he is the only professor who is a former Gryffindor student, also as Head of Gryffindor! She further hires Tonks as his "apprentice", to take over for him when he is... indisposed... and hopefully gain enough experience that she is qualified to take over the post if and when he moves on to teach Defence Against the Dark Arts at a later time. Filius Flitwick is named Deputy Headmaster.

When the students return from Christmas break, all luggage is searched by a team of aurors and unmentionables and Peter Pettigrew is found. Aurors then notice Ginny's reaction to the announcement that the Chamber of Secrets case has been solved, and all five Weasleys present are taken aside for questions; Harry and Hermione are brought along, and Arthur and Molly brought in by floo. The diary is found, and Harry gives pensieve evidence of Lucius Malfoy planting it among Ginny's books. Ginny is given out-of-school suspension, during which she is to see a Mind Healer. Algernon Croaker reveals to Madam Bones and McGonagall that the diary is a horcrux, meaning that Voldemort isn't dead. And the house elves find a portrait of Harry's parents that Dumbledore had hidden.

Hanna Abbott and Susan Bones try to apologize for believing the rumors about Harry being the Heir of Slytherin, when they rather should have defended him as a joint member of the Great Alliance. Harry sets up a meeting for all the children of the Alliance, so that he can set things right and learn about everything he and they are expected to do. More immediately, however, he meets with his betrothed, Daphne Greengrass and Padma Patil, and Padma's twin sister Parvati; due to restrictions placed on her by her father, Padma moves into Harry's Lord's Quarters, and Daphne expresses the wish to do so as well before the other Slytherins find out she is engaged to "*the* Gryffindor Golden Boy".

When Lucius Malfoy is arrested, Narcissa is happy to see him gone and even volunteers evidence against him in the form of his collection of Dark artefacts.

Since Harry hasn't let her out to play, or even talked to her, for six days, Rose is getting bored and takes an opportune moment to wrest control of their joint body – in front of Daphne, who gets understandably shocked at seeing her betrothed suddenly turn into a girl, for no discernible reason. She and the Patil twins demand answers, and Hermione is forced to explain parts of the situation that she and Harry had planned on keeping secret a while longer. She is eventually able to talk Rose into retreating, promising her a "girls' night in" during the upcoming weekend, but not before Rose has let slip her feelings for her. When Harry returns, Daphne again airs her need to move out of the Slytherin dorms before her connections to Harry becomes widely known, and plans are drawn up to have her move in as well. Harry and Hermione talk with Parvati, who is afraid she'll become the third or fourth wife of one of her father's Indian business partners, and they agree to a plan: try to set Lavender Brown up for a marriage with some other Great Alliance heir, so that Parvati becoming her sister-wife keeps the next generation of the Patil family in the alliance, but if this has not been accomplished by the time Harry's contract with Padma is finalized she can join them instead.
