The Rain Card has the ability to create rain and torrential downpours over a single person/area. Rain is a mischievious card that will create a downpour over a person that tries to spoil its fun. It is the sister card to The Cloud and, possibly, The Storm Cards. The true form of Rain is a small, elvish child in a jester costume with raindrops hanging off its hat all in a light blue color palette. It is under The Watery.
The Rain first appears in Episode 4. Rain was in Sakura's house and awakened The Wood when it rained on its card since "water excites Wood". When Sakura, Tomoyo, and Kero reached the basement, Sakura used The Watery to subdue it.
