I Accidentally Went Back to 3rd Grade

This question isn't simply a question of who your favorite character is. It's a matter of who, of those characters, you would want to be. So I'll start out by saying that I have plenty of favorite characters, but there are things about each that make me hesitant to say I'd want to be them. Sherlock is pretty dang awesome in my mind, but let's face it, he's a jerk. Ditto for Kirk, though the ability to be a starship captain sounds awesome, it's also terrifying. Numerous characters from the anime Puella Magi Madoka Magica come to mind, but I won't even try to get into why I'd rather not be any of them.

What I'm saying here is, wow this is a difficult question. So I'm gonna go off into no where with a completely random and silly response and say that I would like to be Sakura Kinomoto from the anime/manga Cardcaptor Sakura. 

Like, seriously, look at this little cutie. She's a 4th/5th grader at the time of the story, and regardless of how young she is, she's also the protector of the Clow Cards, which, without going into too much detail, means that she wields a ton of power for a little girl. She has the protect the world from these things, all while befriending the cards and trying to be a typical 4th grader. Except, really, she has a lot more freedom at home than she should have.

So her friends are really great too. Her bff Tomoyo Daidoji has been with her since forever and dotes on Sakura like crazy. She records Sakura being a hero, as well as makes outfits for Sakura to wear during her fights.

Pretty much like that

Her other good friend was originally her "rival" (as stated by Tomoyo) but the two of them eventually become really close. Syaoran Li was a Chinese exchange student who was sent to capture the cards before her (he was actually probably better than her at first, but loses to her anyway). 

Oh yeah, he's also her love interest.

But enough about her friends. She's just really sweet and kind, and she's able to do all of the things that she does, even though she's such a young little girl. She's the first Master of the Clow since Clow himself, who created the cards. All in all, I think she's pretty cool, and she's also one of the first fictional characters I ever idolized ever. (The first was either Sailor Moon or Yugi, dunno which one).
