Card Captor Sakura - episode 20

Lee's favourite relative has moved in to live with him and has quickly enrolled at Sakura's school. Meilin is similar to Sakura in many aspects: both are very athletic and energetic. All but one detail sets a stark difference between them: Meilin is really possessive of Lee and hates it when another member of the weaker sex so much as engages him in conversation. This really doesn't do much of anything except embarrass Sakura, because she's too kind to do anything to antagonise the school's new arrival. As it turns out, Meilin is already aware of the Clow Cards and immediately sensed that Sakura was also in on the whole Magic Card hunting business. This causes Meilin to quickly label Sakura as their rival, and she will anything she can to aid Lee, thus proving that they are the ones truly meant to succeed in this trade. Meilin's debut also serves to showcase her skills as a fighter, despite her being the same age as all the other characters. This doesn't matter much, as she proves a formidable opponent to take on the Fight Card, at one point even having the upper hand in the bout. Nonetheless She can't do much on her own, but she is still useful in wearing off the opposing spirit to facilitate Sakura's job to capture it.
