NO ONE garra is the youngest kazekage and there was gap probably a year with no kazekage. i don't believe that there was no kazekage for 3 years. Garra was established as a great kazekage before akatsuki attacked.People who are saying ''his dad'' either didn't read the question, or are just trolling.
Who was the kazekage before Gaara and AFTER his dad, meaning who was it BETWEEN that period.
