Ino Yamanaka

Ino is a student at Konoha Gakure and a close friend to Sakura and Hinata. The three of them are very close since before the series start. She is also Sai's girlfriend, and friends with Naruto and Sasuke thanks to that

Personality
Ino is a fashionista, always trying to look better and prettier. She is kind and cheerful most of the time, but she doesn't mind resorting to violence to those who are mean to her friends, such as Karin. While she's generally comprehensive and compassionate, Ino can also be very jealous and switch moods immediately.

Another important trait of Ino's personality is that she enjoys very much teasing on people, specially her friends. For example, bothering Naruto with his thoughts about Hinata in a swimwuit. However, she does not like it when someone teases her.

Appearance
Ino is a fair-skinned girl of average height with soft baby blue eyes. Her most noticeable trait in her appearance is her long blonde hair, which is always seen in a high-ponytail with bangs covering the right side of her face. She wears the standard Konoha Gakuen uniform in the beginning, but as from the Summer Vacation arc onwards, her outfits vary.

Sai
Sai is Ino's boyfriend. The two were dating since before the series start, and were seen together all along the series. When they started seeing each other in unknown, but it is evident they like each other very much. Sai generally calms Ino down when she gets too excited or goes too far with her teasing, and Ino proved that she can be a jealous girlfriend on the Art Exhibition arc, to the point of punching Sai after he comments on Sakura's breasts.
