Being part of the akatsuki was no joke, you were apart of a high level terrorist group. Meaning you had to do a lot of missions and killing— showing no mercy to your enemies, you were also known as the "Gentle but ruthless killer of the akatsuki."

no one knew your background since you were always so sweet, but you were the daughter of the hashirama senju and mito uzumaki, One day you were laying on sasori's lap as the others, konan,pain,kakuzu,hidan,itachi,kisame,tobi and deidara sat next to each other in the base. Tobi walked in with a familiar face to me, Madara uchiha?! I sat up as fast as I could.

Madara: "Hello there, princess of the senju clan. I'm surprised to see you here but of course..no one can surpass your father at killing me, so I see you've inherited his strength. Hm?"
