In this fanfiction, Hermione might find an ally in an old, retired dragon rider who lives on the outskirts of the wizarding world. This person has years of experience with dragons and could teach Hermione valuable skills. Also, the Weasley twins could be her allies. They're always up for some mischief and adventure, and Hermione's dragon - riding would be an exciting new project for them. They could use their inventive skills to create useful gadgets for Hermione and her dragon.
Perhaps some of the more nature - loving and adventurous students at Hogwarts, like Luna Lovegood. Luna has an open - mindedness that would make her accepting of Hermione's dragon - riding. She could also offer her unique magical insights and knowledge of strange creatures to help Hermione in her dragon - riding journey. Another possible ally could be Hagrid. Given his love for magical creatures, especially dragons, he would be more than happy to assist Hermione with taking care of her dragon and teaching her about dragon behavior.
Harry and Ron could be her main allies. They've always been by her side in the original story, so it's likely they'd support her new adventure as a dragon rider. They could help her keep her dragon - riding activities a secret from the teachers at Hogwarts.
Neville could be an ally too. His skills in herbology could come in handy when it comes to finding the right plants to feed the dragons or to use for medicinal purposes. Also, Luna Lovegood might be involved. Her unique perspective and knowledge of strange magical creatures could give Hermione new ideas on how to care for the dragons. She might know of some obscure spells or methods that are beneficial.
Another Kamen Rider from the same series who has a different view on justice could be an ally. They might see that Cronus's power could be used for good if guided in the right direction.
Harry and Ron would most likely be her allies. They've always been by her side through thick and thin. Neville could also be an ally as he has shown courage and a willingness to stand up for what's right. Luna might be another one. Her unique perspective on things could be really helpful in a rebellion.
Natsu could be one of her potential allies. Since he is a dragon slayer himself, he could understand some of the challenges Lucy faces as a Dark Dragon Slayer. He might offer his fire - based powers to complement Lucy's dark dragon slaying abilities. Another could be Erza. With her strong combat skills and leadership, she would be a great asset in battles against dark dragons. Erza could also protect Lucy when she is still learning to control her new powers.
Harry and Ron would be her most likely allies. They are her best friends, and even if they might be initially shocked or jealous of her being in the tournament, they would surely come around to support her. Another likely ally could be Cedric Diggory. He's a fair - minded and kind wizard, and he might see Hermione's intelligence and skills as an asset and offer to help or at least be friendly towards her.
A powerful dark wizard could be the main antagonist. He might be jealous of the dragon rider's powers and the bond with the dragon, and wants to break that bond and steal the rider's powers for himself.
It could be a powerful dragon hunter. This person would see Naruto's dragon as a prize to be captured or killed. They might have a personal vendetta against dragon riders in general.
Sakura could be one of her main allies. Even in a samurai - themed story, Sakura's medical skills and combat abilities would be useful. She could support fem Naruto in battles and help heal any wounds.
Harry and Ron could be her obvious allies. They've been through so much together, and if Hermione has a reason to get revenge on the Order, they'd likely stand by her side. They trust her judgment and would be willing to help her out.
Dumbledore could also be an ally. He is very knowledgeable and might give Hermione some advice or information about the vanishing cabinet that she needs to successfully sabotage it. He might also provide some protection if there are any risks associated with her actions.
