(Crossover) Miss Izuna

As the daughter of the Uchiha clan chief, young Izuna's main job is to act cute and cling to people. Then one day, Nana sees a ghost. The ghost girl is adorable, with brown hair and brown eyes, and she's an expert in genjutsu. She got caught up in time travel by accident and lost some of her memories, but she still teaches Izuna, the only one who can see her, plenty about genjutsu, along with two important truths. First, red-haired women are mostly good people. Second, silver-haired men are all bad news. Nana thinks the ghost girl is amazing. Most of her genjutsu lessons are very useful. The only thing Nana doubts is the second truth she told her. As time passes, Uchiha Izuna becomes a renowned genjutsu specialist and works hard to make a red-haired big sister (Uzumaki Mito) her sister-in-law. Much, much later, Izuna discovers that both truths the ghost girl told her were right. Silver-haired men really are all bad news! Senju Tobirama has been feeling utterly devastated lately. He could have handled learning that the little girl he saved as a child, and who later saved him in turn, was from his sworn enemy's clan. But of all things, he had to fall in love with her. The fact that he fell for Uchiha Izuna was already driving him crazy. And just when he finally accepted that he was gay, he discovered... His sworn enemy was actually a girl? P.S. The ghost girl is Rin Nohara, the heroine of the first chapter, "Novels About Teacher-Student Romance Are All Lies!", in my collection, "Fantasy Paradise (Idea Collection)". This Rin Nohara is a girl who fantasizes about pairing up with her teacher's wife (not really!). She likes her red-haired teacher's wife and dislikes her silver-haired childhood friend. Izuna is gender-swapped. Tobirama and Izuna, Hashirama and Madara. In the original, Judy is flanked by Madara on one side and Mito on the other, while Izuna is constantly trying to set the two of them up. Judy must be feeling utterly devastated.
