Haze Quadruplets

They are quadruplet brothers hailing from the Land of Haze who specialise in Haze-Style kinjutsu. Orphaned at a young age, they were raised in an orphanage where they appreciated having a home at all to call their own, and such grew up to become very committed to serving their country. They have a rule that each abides to of always sharing everything equally amongst each other.
They were tasked in retrieving cells of the First Hokage, Hashirama Senju. Ultimately, their group efforts and respective sacrifices failed, as each brother met their demise in battle.
