Neihoshi had one of the the most powerfull person alive in the position as kage...but this power in the end was his downfall.Neikage was a jinchuriki.Neikage Yamato Raito had within him Yonbi the four tailed beast.His attacks where mainly poison-type.Dzukitonami planed a large-scale attack against Neihoshi...the village's military status was really low.They had only one forth of Dzukitonami's army.The situation looked grim for Death Star but Yamato was determined to sacrifice all he has to protect the village.He wanted to realease the 4 tails from within him...that way Death Star may have a chance to survive.He spoken with the village elders who put the bijuu inside of him in the first place...he wanted the seal broken, they refused to release the seal cause of the risk of the bijuu migiht attack Death Star instead, but Yamato was not the type of person that you would like to refuse.He cut the village elder's arms with a poisoned kunai saying that in 2 days they will die if he doesnt administrate them the poison's antidote.The attack was about to begin in 3 days.The village elder accepted to release the seal of the Yonbi and gave Yamato a scroll saying that it was the key that unlocked his seal.Then Yamato started to laugh at the elders saying that the kunai wasn't poisoned...it was even sterilized so their wounds will not infect.The day of the battle came and from the village's towers the shinobi could see the army was 3 kilometers distance from the village.Yamato quickly ran towards them.When he was at exactly one kilometer away from the village he used the scroll to unlock the seal.Imediatly 4 tails came out of him and he started to take the bijuu's form.The army was only a half hour away by foot witch it took the Yamato a minute to reach.He slaughtered all the shinobi in his way.Nobody stood a chance against him...but Yamato couldn't hold on much longer.The 4 tail's chakra had infected his entire body and he was dying.He only had destroyed half of the entire army.Before dying his last words where "i made a pact with the 4 tails...if you ever attack Neihoshi...Yonbi will destroy Dzukitonami".With those final words Yamato's life came to an end and the 4 tails had escaped from him and ran across the lands.Dzukitonami never attacked Neihoshi ever again from that day...
