Sakura and Her Kind Father

Fujitaka is very busy organizing materials for his presentation, so Sakura and Toya offer to do all the housekeeping chores so their father can concentrate on his work. Taking Kero and Tomoyo with her, Sakura brings some food to Fujitaka working in Towa university. There, they meet Fujitaka's assistants, who show them Fujitaka's lecture. Afterwards, Sakura finds her dad sleepy because he has slept so little, so Sakura and Tomoyo buy him and his assistants coffee. When they return, Fujitaka's assistants fall asleep before her eyes. It turns out that the Sleep Card is loose at the university.
