Obviously, Naruto is one of the main characters. Since it's about him being the son of a witch, his character development and exploration of this new identity are central to the story.
Another possible plot is that Naruto's witch heritage is linked to an ancient prophecy. According to this prophecy, he is the only one who can defeat a powerful dark force that is emerging. So, he embarks on a journey to master his witch powers and fulfill the prophecy, facing many challenges and making new allies along the way.
Well, it could be about Naruto having some of Scarlet Witch's powers. Maybe he can use her reality - warping abilities in the Naruto world. For example, he could change the landscape during battles, like turning a desert into a forest to gain an advantage.
One possible plot could be that Naruto, being the son of a witch, has to hide his identity in the Soul Eater world. He might struggle with the fact that witches are usually seen as enemies there. He could use his ninja skills in a unique way, like combining them with any latent witch powers he has. For example, his shadow clone jutsu could be modified by his witch heritage to create clones with different magical abilities. And he might form an unlikely alliance with the main characters of Soul Eater to fight against a common threat that targets both his witch side and the Soul Eater world.
He would likely become more complex. His usual determination would be combined with the power - hungry and sometimes unpredictable nature of Scarlet Witch's powers. He might struggle with controlling these new powers at first, which would make him more cautious and introspective.
A witch character with the power to create illusions that are even more powerful than those in the ninja world would be really fascinating. She could use these illusions to deceive Naruto's enemies or even to teach Naruto new ways of using illusions himself. Also, a witch who has a deep connection with nature and can use nature's magic in the middle of the ninja world's battles would be quite an interesting addition to the fanfiction.
A popular one is 'Naruto's Witch Encounter'. Here, Naruto meets a young witch during one of his missions outside of the village. She has a special mission of her own that somehow gets intertwined with Naruto's goals. As they work together, they discover new abilities within themselves and a deep connection forms between their two very different worlds.
In 'Naruto and Witch' fanfiction, a frequent theme is the exploration of the unknown. Naruto, who is used to the world of ninjas, enters the realm of the witch's magic, which is full of secrets and mysteries. This exploration can lead to personal growth for Naruto. Another common theme is the idea of balance. The power of the witch and Naruto's power need to be balanced, and often in these fanfictions, they struggle to find that equilibrium. And of course, friendship or partnership is a big theme as they learn to work together and rely on each other's strengths.
Well, Naruto's powers would likely be a mix of his ninja skills and his witch powers. His ability to create shadow clones might be enhanced by his witch heritage. In the Soul Eater universe, these clones could potentially have their own souls or be made up of a different type of energy. His Nine - Tails chakra, if it exists in this fanfiction, could also be affected. It might react with the witch magic in unexpected ways, like creating a new form of power that combines the raw power of the Nine - Tails with the magical aspects of being a witch. This new power could be used to combat the kishin or other powerful enemies in the Soul Eater world.
Well, perhaps the story could involve Harry having to deal with the dark legacy of the White Witch. Maybe he discovers powers within himself that are both a blessing and a curse due to his relation to her. He might struggle to be accepted by his friends who are wary of his newfound connection.
