(AU) There are many things that make a great ninja. Sakura Haruno may not be physically strong, but she is quite intelligent for her age, and she wants to be a great kunoichi like Tsunade. While practising her espionage skills at 10 years old, she uncovers Naruto's dark secret...which may very well lead to a more coherent Team 7... (No Sakura-bashing here. Don't like, don't read)
