Being a rare possessor of his clan’s Shikotsumyaku kekkei genkai, the clan patriarch feared Kimimaro’s abilities and had him locked up in a cage unless needed for battle. The Kaguya clan was wiped out when they attacked Kirigakure, seemingly for no reason other than the desire to kill and show off their ferocity. Having underestimated their opponents’ defences, they were slaughtered, with Kimimaro the sole survivor. Wandering soon after, Kimimaro was eventually found by Orochimaru, and recruited as one of his most loyal ninja.
