Found with The Wood, it was originally grimy and Sakura didn't
know what it was. She carelessly placed it on a shelf and got
sidetracked running errands for her father and having lunch with
Yukito. A playful card, The Rain uses its powers to make The Wood
When Sakura returns and is battling the growing wood in her house, she
remembers she found a second card. Telling Kero, he insists she go into the
basement to investigate. It is there she finds The Rain, which giggles and
coos at her before playfulling chasing Sakura through the stacks of
books, trying to get her wet.
Sakura summons Watery which allows her to control the rainfall. The water
it is dropping turns into wide band which wraps about the Watery just above
Sakura. Turning this stream against The Rain, it binds the small card form into
a large water bubble. She then seals a sad looking Rain into the card. The
rain tries desperately to escape, but to no avail.
It's antics with The Wood completely messed up the house and
Sakura, Kero and Tomoyo were forced to clean the entire thing all
over again. Exhausted, Sakura and Kero collapse on her bed leaving
her cake to the never full pit of a stomach known as Touya. Ooops.
Oh well, she was too tired to eat anyway.
The Card's Power:
To create and control rainfall.
Appearances and Uses in Other Episodes (up to ep. 27)
Used in a special episode where Sonomi arranges for Sakura to meet her
grandfather (though Sakura never knows him for such). Seeing a picture his
granddaughter (Sakura's mother) drew as a small child of a rainbow, Sakura
decides to make him happy by making that rainbow appear outside his house.
She uses The Rain to accomplish this.
