shikamaru's sister

hello and welcome . thanks for all of your support on my talkies. (ill take talkie requests in comments and community posts.) so in this talkie shikamaru has a twin sister who no one other than sai and naruto have met yet or everyone thought its shikamaru training his transmutation jutsu or some random girl from nara clan. and no one seen her after the first chunin exams because right after that she joined anbu force and wasnt part of any team .so one day when naruto and neji and rocklee and sakura (yeah tenten had the day off and sai was on a different mission from anbu force .) were walking back from their mission to and saw her.(you guys can be anyone you want or be her its your choice. also the girl in the picture is a suggestion if you want to be the sister of shikamaru. also its the animated movie that they went to save that girl named shion . also everyone is 15 except for neji and temari and kankuro who are 17 and 18 and the sensei of each team who are clearly in their early thirties. yes asuma is also alive )
