ACGOMN: This is for Matt and T.K. again
Don't own Naruto, got it
Rin
Rin is a medic ninja.
Rin is on the same team as Uchiha Obito, Hatake Kakashi, and the future Yondaime.
She healed the boys when they do something stupid and get hurt.
Rin had a crush on Kakashi, but really loved Obito and didn't admit it.
She knew Obito loved her, and that made her extremely upset when he was killed.
Rin transplanted the one good Sharingan eye of Obito, seeing on how the other part of the body was crushed under a giant rock, to Kakashi.
Only Kakashi knows what happened to her after that.
She either died or couldn't take the emotional stress of losing both a teammate and sensei and retired from being a ninja and left Konoha. It's most likely the former.
ACGOMN: There you go Obito is next followed by Kakashi.
