A huge fan of martial arts, as well as usually being upbeat, cheerful and energetic, Chie is one of the first characters to join Persona 4's party. She does, however, have an occasionally short temper, especially with Yosuke Hanamura. Her initial persona is Tomoe Gozen of the Chariot Arcana.
Overview

Chie Satonaka is one of the characters in Persona 4, joining the party early in the game. Although she has a short temper, even with friends, she is in reality an extremely protective person, especially when it comes to her best friend, Yukiko Amagi. Chie is also a huge fan of steak and kung fu movies, often bringing them up in normal conversation or going so far as to spontaneously yell out battle cries. Like the other girls in the party, she has little in the way of cooking skills and often botches major dishes. Additionally, the player can also choose to date her or become good friends with her via Social Link events.
Combat
At the start of the game, Chie is primarily used as a caster of ice magic. Her main strength in combat, is her physical prowess. Despite the fact that there is a large gap between her skills, by the end of the game, with the combination of "God's hand" and "Power charge", she does considerable damage with melee combat. Chie is one of the only characters that doesn't learn a party wide buff, only keeping "Tarukaja" which focuses on one character. Chie attacks using her powerful feet, and her weapons are usually variants of shoes or greaves. Her followup attack is widely known as the most useful ingame, the Galactic Punt. This move instantly removes an enemy from combat, taking out any standard enemy, and a few select sub-bosses.

Shadow Chie
Chie encounters her Shadow and, by extension, unlocks her initial Persona Tomoe early on in the game at Yukiko's Castle. While there, she is forced to confront several of her issues in front of the then small party. Among them are her jealousy of Yukiko for easily being able to exert her feminine traits, as well as her desire to hold onto Yukiko in order to have a sense of control over someone. Yukiko had historically, after all, been very dependent on Chie for the duration of their friendship. Although Chie initially denies having such sentiments within her because they aren't her true intentions, after recognizing that they are indeed there and her need to keep them in check, she accepts those parts of herself in the end. In doing so, she joins the party in earnest and starts down the path of reconciling the dark aspects of herself.
Social Link

The character designs of Chie's Personas are highly referential to kung fu legend Bruce Lee.
After awakening her own Persona in the Midnight Channel, Chie is made to come to terms with a number of different things, most notably how to best be protective of people without being overbearing, as well societal perceptions of her lack of feminine traits. This is evident in the end part of her link, where she is protecting a young child against bullies. Should her Social Link with the main character reach the maximum level, she learns to overcome the former after accepting that she doesn't have to go at it alone in situations where others need protection. The latter issue is tackled more directly should the player opt to date her. At the end of the game, she tells the main character that it's her dream to join the Inaba police force and she also hopes to work under Ryotaro Dojima so that she can protect the place that she loves and its people.
After completing Chie's Social Link the protagonist receives a wrist band and the ability to create the persona Futsunushi of the Chariot Arcana. Her persona also transforms into Suzuka Gongen upon the Social Link completion, removing her weakness to fire.

Trivia
- Chie and her parents own a dog that Yukiko was clutching when the two met. It has apparently grown to be fat and stinky.
- After a battle, one of Chie's lines is "Don't think...feel" is a reference to Bruce Lee, when his character says the same line in the movie Enter the Dragon.
