Sakura, being born on March 28, is an Aries. People believe that a lot can be said about a person by which zodiac sign they were born under. Is that true of Sakura? Well, let's take a look! Here's what Astrology.com has to say about Aries:

"Aries is the first Sign of the Zodiac, and that's pretty much how those born under this Sign see themselves: first. Aries are the leaders of the pack, first in line to get things going. Whether or not everything gets done is another question altogether, for an Aries prefers to initiate rather than to complete. Do you have a project needing a kick-start? Call an Aries, by all means. The leadership displayed by Aries is most impressive, so don't be surprised if they can rally the troops against seemingly insurmountable odds -- they have that kind of personal magnetism. An Aries won't shy away from new ground, either. Those born under this Sign are often called the pioneers of the Zodiac, and it's their fearless trek into the unknown that often wins the day. Aries is a bundle of energy and dynamism, kind of like a Pied Piper, leading people along with its charm and charisma. The dawning of a new day -- and all of its possibilities -- is pure bliss to an Aries."

When Sakura first makes her appearance, she certainly seems to only think about herself (ie: she bitches Naruto out so she can sit beside Sasuke, not caring how Naruto would feel about it). As the series goes on, she begins to care more about the people around her and becomes less selfish, but at the same time, she also becomes preoccupied with herself and how much of a burden she is to her companions. Sakura certainly has leadership qualities; she's smart, quick to give commands and after training with Tsunade, would be ideal as a group leader. I'm not sure how much of a "pioneer" Sakura is though, as she usually doesn't take unnecessary risks nor does she jump into things without thinking them over. She certainly is a bundle of energy though! ^^

Astrology.com continues to say: "The symbol of Aries is the Ram, and that's both good and bad news. Impulsive Aries might be tempted to ram their ideas down everyone's throats without even bothering to ask if they want to know. It's these times when you may wish Aries's Sign's symbol were a more subdued creature, more lamb than ram perhaps. You're not likely to convince the Ram to soften up; these folks are blunt and to the point. Along with those qualities comes the sheer force of the Aries nature, a force that can actually accomplish a great deal. Much of Aries's drive to compete and to win comes from its Cardinal Quality. Cardinal Signs love to get things going, and Aries exemplifies this even better than Cancer, Libra or Capricorn."

"Blunt and to the point" describes Sakura fairly well; she never seems to hesitate to say what's on her mind and she doesn't waste time getting to the point, no matter what it is that she has to say (ie: on her first mission, she right out said they should go back to Konoha because they were too weak... she also has no problem calling Naruto or anyone else an idiot if they're acting like one). I would also agree that Sakura certainly has a strong drive to compete (ie: her relationship with Ino and her desire to become a strong shinobi).

So... overall, I think that there are a few discrepancies but Sakura does fit in with the Aries description, much better than expected.
