A magic circle (魔法陣, Mahoujin) is a figure composed by a great number of symbols related to the powers, techniques and procedence of the magician. Generally, the magic circles are what differentiates mages from one another, each creates a magic circle of their own - it is like their signature. Magic circles work as an field of energy that activates the moment a mage is about to perform a spell. This magic circle is visible under the mage's feet, and its power surrounds him/her as if it was a Ki or Aura.
Clow Reed's Magic Circle
The figure for Clow's magic circle consists of a 12 point-star, with the symbols of the cardinal points inside thecorners. It has the image of the Sun in the centre, and next to it is the Moon. Clow's magic is symbolized by "Light and Darkness", and his guardians are Cerberus (Sun) and Yue (Moon).
Clow's magic is also a mixture of both Western and Eastern magic (having an English father and a Chinese mother), so it also has both Chinese and English characters on it.
- This magic circle is the same used by Yukito (TRC Ch. 1), Fei Wong Reed (TRC Ch. 183), Xing Huo, and Syaoran Li and Watanuki (TRC Ch. 213).
Sakura Kinomoto's Magic Circle
The main symbol in Sakura's magic circle is the Star within it. Like Clow's, it forms a 12-point star with three squares, surrounding these are the symbols of the Occidental Zodiac. Next to the 10-point star in the center are the Sun and the Moon. These represent Cerberos and Yue, who protect the star, meaning Sakura.
During the final confrontation with Eriol Hiiragizawa , Cerberus and Yue’s powers are combined into Sakura's staff. This once more transforms her staff into a final Guardian version, although the magic circle stays the same. Sakura’s magic is drawn from the power of the stars, which may start small, but are ever-shining with their own brilliant light.
- This circle is the same used for Sakura Li , maybe due to the fact that she recieved the Star Wand from Sakura Kinomoto.
Syaoran Li's Magic Circle
From the characters closest to the yin-yang symbol, and going around clockwise, they read:
冬、春、夏、秋 - winter, spring, summer, fall
水、火、風、地 - water, fire, wind, earth
北、東、南、西 - North, East, South, West
天、鬼、地、神 - Heaven, Demon, Earth, God
