Sakura, Tomoyo and the Big House - S1.E11

Sakura is invited to Tomoyo's home for the first time. She is shocked to find Tomoyo's house to be an elaborate mansion with maids. Sonomi rushes over when she hears of Sakura's visit and shares the memories of Nadeshiko with Sakura over tea. While Sonomi is taking care of business over the phone, Tomoyo presents a special box and explains the key to the box bounces out whenever she tries to open it and Kero senses it's the work of a Clow Card. Sakura uses the Sword card to slice away the protective barrier of the Shield card and captures it. Inside the box is a dried bouquet of cherry blossoms from Sakura's mother's wedding and the first present Sakura ever gave Tomoyo, an eraser shaped like a bunny.
