Sakura’s fever is running high, but she tries her best to power through it. She doesn’t want to miss out on making posters with Tomoyo, and she worries that her dad will abandon an archaeological dig if she calls in sick. And of course, she has to take care of her little sister Meiling and look after her sickly mom. Touya can sense that something is up, but she doesn’t want him to tell her, so she tries to convince him she’s just fine.

Despite her best efforts, the fever persists. And soon she feels a strange presence in the air, which Kero-chan identifies as Cloud. Even though Sakura’s head is spinning, she knows what it means: the time for sealing Clow Reed’s cards is drawing close. Sakura can feel it in her bones. Kero warns her to stay in bed, but she’s convinced that only she can do this job.

But the clouds are too thick to allow for any seals, and if she doesn’t hurry up, it will be too late. With all of the people she loves depending on her, she can’t simply let it go. So she decides to go out anyway, despite the roiling of her stomach and the fact that she’s barely breathing.

Her dad and Meiling assure her that they’ll handle the poster work without her, and she also has to worry about her little sister. But Touya can sense that something is off, and he insists on accompanying her.

The Sakura_39, or cherry blossoms, are the symbol of springtime in Japan. They bloom for a very short period of time, usually beginning in late March or April and ending by mid- to late May. Each year, people visit the sakura to enjoy their beauty and to remember the passing of time.

But when the flowers begin to die, it’s up to Sakura to save them. If she doesn’t do this job, the sakura will lose their beauty and their magical powers. And if that happens, it will be too late for the people who depend on them. This is one case where it’s impossible to put Sakura’s health above everyone else’s.
