Rebirth of a legend.

"Farewell Yamamoto genryuusai, the reason you lost to me was because you became soft." those were the last word the head captain of the twelve squad heard before losing his life, thankfully the soul king decided to reward him for all of his years of services, having a new mission for him he gives him the choice to pass away peacefully or take the new chance to live.
Accepting the mission Yamamoto is sent to the world of ff 7 in the body of a little boy named Cloud Strife.
