And in case you still try to tell me sayuri is too young to participate:

Obito and Kakashi graduate from the academy at the same time. From the mother site, Obito graduates at 9, Kakashi at 5. There is a 4 year difference. Obito, time of 'death' is 13. 13-4 = 9.

8 + 1 = 9, give or take a few months, maybe a few weeks.
