Haruto of the Red Dawn

Namikaze Haruto is neglected, but he's fine with that. His younger sister Naruko deserves the training since she's the Kyuubi Jinchuuriki. Taking over Itachi's role, he slaughters the Uchiha clan and escapes the village in search of the Akatsuki, preparing to infiltrate it for the sake of his village. Slight RWBY crossover with Ruby Rose replacing Hidan and Haruto's love interest.
