I am also using a great deal of creative libirties when writing my character background, and an approach I've never done before. Here, to hoping it doesn't back fire on me! Cheers! *raises a glass*
Noooo..... Well, okay. She is going to be a little more well rounded that just a pure healer, as all the medical ninjutsu she knows at the moment is the First Rank of the actual healing one, and the one that increases the targets natural healing rate. But yeah, she has the levels in Medical Specialist. *hides a few advanced seals behind the back* Guess what Seal jutsu she will have! A hint: it may or may not involve being a bomb.
Tempted to also ventually make her a Sage, but that would be tredding on being too close to being a semi-Naruto clone.
Also, a random note, since the standard mixture is 2 males to 1 female on a genin team, making a female character could help your chances of getting in. Unless everyone makes a kunoichi in which case it would be better to make a male character.
