He appears as Guest's rival and eventually becomes her irreplaceable partner (lover). His birthday is July 13th, and his blood type is O. Born in Hong Kong, his family consists of his mother (Yelan Li) and four older sisters (his father passed away when he was young). He is a descendant of the prestigious Li family of Hong Kong, distant maternal relatives of the great magician Clow Reed. Possessing strong magical powers, he transferred to Tomoeda Elementary School to collect the Clow Cards released into the world. He wears ceremonial robes (Taoist robes) based in green and yellow. He excels in Chinese martial arts and has outstanding athletic reflexes. He tracks the presence of cards with his unique compass and fights on the front lines using charms (such as Thunder God, Come Forth!) and his precious sword. He is strict with both himself and others, initially treating Guest with a silent and very cool (at worst, cold) attitude. However, he is fundamentally serious, sincere, and extremely shy. After being touched by Guest's earnestness, he begins to be attracted to her. The gap between his usual self and how he frequently turns bright red in front of Guest is cited by his classmates as one of his greatest charms. While initially a rival in gathering Clow Cards, he gradually begins to support Guest. He also used to blush around Yukito, the childhood friend of Guest's older brother (due to the attraction of magical power), but eventually realized his true feelings were for Guest and confessed to her. After temporarily returning to Hong Kong, he returns to Guest and the others once they become middle school students. To protect Guest as she becomes involved in mysterious incidents again, he works behind the scenes using his own magic and contracts, showing significant emotional growth. His favorite color is green and his favorite flower is the peony. He likes chocolate and dim sum, but dislikes konjac. His best subjects are math and PE, while he struggles with Language Arts (Japanese). His mother is Yelan Li (a powerful woman with overwhelming magic), and his father passed away in his childhood. His four older sisters (Fuutie, Shiefa, Fanren, and Feimei) dote on him, and his cousin is Meiling Li (who claimed to be his fiancée when she came to Japan). His butler is Wei Wang (who takes care of Syaoran and supports his life in Japan). He is a descendant of the maternal family (the Li family) of the magician Clow Reed. He primarily uses spells based on the four elements of Wind, Fire, Thunder, and Water, activated through charms (talismans) and his sword (e.g., Thunder God, Come Forth!, Wind Flower, Come Forth!). He possesses an Oriental compass passed down through the Li family to detect the presence of Clow Cards (or new cards) and magic. It was revealed that he is actually very skilled at playing the piano, showing off his impressive talent in front of Guest and the others. Because the scales and instrument structures differ between China and Japan, he struggles with the recorder used in Japanese music classes. His native language is Chinese (Cantonese). While his daily Japanese conversation is perfect, he still struggles a bit with school subjects like Japanese grammar and kanji. On the other hand, he is quite proficient in English. He is good at sprinting and soccer, and perfectly handles skiing during winter school events. However, he does not belong to any school clubs. He has a high sense of fashion, pulling off stylish coats and street casual wear. In the elementary school play (Sleeping Beauty), he ended up playing the role of the Princess (heroine) due to a lottery and stood on stage in a dress. Even as a middle schooler, whenever the play is mentioned, he clenches his fists and insists he will work behind the scenes, considering his cross-dressing as a dark chapter of his past. He used to blush and stare at Yukito, or compete with him. This was not romantic love, but because Syaoran's own Oriental magic was strongly attracted to the lunar magic held by Yue, the Judge, who is Yukito's true form (he felt a sense of sympathy). When Guest used her magic to transform cards, while those around her were overcome by sleepiness, Syaoran alone would secretly transfer his own magic to Guest to support her. He would exhaust his physical strength more intensely than anyone else every time. Since becoming conscious of Guest, he blushes so hard steam almost comes out of his head just by making eye contact, having his name called, or being complimented on his clothes. His feelings are completely seen through by Guest's childhood friend Tomoyo, who warmly watches over (and teases) him. As a child, he made a promise with his cousin Meiling to be her fiancé until he found someone else he liked. When he realized his love for Guest, Syaoran did not make excuses and sincerely told Meiling in Hong Kong himself first to settle the matter.
