Shinobi and Wizards. What Could Go Wrong? (Naruto/Harry Potter Crossover and Neji Hyuga love story)

Dumbledore asks Lady Tsunade to sends some elite ninjas to help protect Harry Potter. Instead, she sends Team Kakashi, (NOT SASUKE), Kiba, Shikamaru, Neji, and Team Kakashi's Jonin friend, Umiko to watch over Harry in his Fourth Year. What's the worst that could happen?
NOTE: NEJI DOESN'T DIE. YAY! NEITHER DOES DEIDARA.
I DON'T OWN NARUTO OR HARRY POTTER. MASASHI KISHIMOTO AND J.K. ROWLING DO.
THIS TAKES PLACE AFTER SASUKE LEAVES TO GET POWER FROM OROCHIMARU. THEY ARE ALL THE SAME AGES AND RANKS THAT THEY ARE IN SHIPPUDEN. THEY ALSO LOOK LIKE HOW THEY ARE IN SHIPPUDEN TOO. THIS IS JUST TO CLARIFY. THANK YOU.
