Kimimaru was infact the best ninja out of the Sound Ninja 5 but everything he did was basically awesome. Too bad it was short-lived. He could have been a good vessel for Orochimaru.
His storyline was indeed a sad one. He grew up in a war hungry clan. And was locked up for quite a while cause of the fear of his bloodline. It's sad to see a child of this prodigy wasted being locked away. The clan itself led to there own demise when they attacked the Hidden Mist village and thus left Kimimaru to fled. He was later found by Orochimaru and led to his life as Lord Orochimaru's servant.*
He cared for his master. We can see that later on he became a part of Orochimaru and thus vowed to be useful to him. His powers grew as the curse mark begin to level in stages. We can see he was a invaluable asset to Orochimaru as he helped killed the 4th Kazakage. At thT time he started to have symptoms to an unknown virus that subsequently ended his life.*
He was bed ridden for the past couple of month. Not knowing what's gonna happen in his position as Orochimaru's vessel. But he knew that shortly he will die. Crying to figure out his usefulness he fled to recover the new vessel for Orochimaru, Sasuke Uchiha.*
After recovering Sasuke and then almost killing Garra. He died. His death led to a valley of bone. His last words were and correct me if I'm wrong "I'm no puppet, he was the only one who gave my life meaning, how can the likes of you understand that!"*
Rest in peace Kimimaru. It's sad to see you gone.
