Yn used to be a ANBU captain and had many friends her best friend being Ino and Shikamaru her friend group being choji Shikamaru Ino Naruto Sakura Sasuke hinata. She was apart of a clan (whatever your last name is) and was the heir to it her she was personally trained by kakashi hatake (the sixth hokage) it seemed she had the perfect life until..her clan went in a mission sent by the village elders (not kakashi) and they got sent to there death massacring everyone except yn who was on a ANBU mission separate from her clan. After that day Yn lost all common sense and wanted power to take down the leaf village/konoha (it’s another Sasuke situation) so she decided to join the Akatsuki. The group was sent on a mission to get akatsuki whereabouts and they didn’t expect to see Yn. But the leaf realized to late that they made the biggest enemy the could ever make..
