Sakura isn’t a fan of ghosts, like, at all. So when her friends suggest they investigate the forest behind the school for signs of haunting, she basically has to be dragged along. Sure enough, something appears in a flash of eerie blue light, but that something is different for everyone. Tomoyo sees a meat bun, but Sakura sees her mother Nadeshiko, who died when she was only three, and the anniversary of her death is approaching.
This is another case where Kero isn’t sure if a Clow Card is at work, but it’s enough of a possibility to visit the spot again, this time with Kero tagging along, Sakura in a kind of Italian opera bunny costume, and Tomoyo with her camera. When the spectre of her mother appears again, drawing Sakura closer, she steps right off the very sheer cliff she herself warned the others about.
Fortunately, Yukito catches her before she hits the ground, but she still passes out. She wakes up at his house, where he makes a point to mention his grandmother changed her clothes, not him, and that her “plush toy” is safe with Tomoyo for the evening. When Sakura contemplates whether who she saw was her mother, Yukito asks her: if it really were, why would she put her daughter in harm’s way?
When Touya comes to collect his little sister, Yukito tags along, and we learn that Sakura’s intense fear of ghosts comes from two things: her innate ability to sense (but not see) the real things, and Touya’s incessant teasing of her when they were younger. While he declares it his right as a big brother to mess with her, I could sense a tinge of regret in Touya’s telling, while Yukito suggests that maybe he can skip scolding her when she wakes up.
The next night, Sakura, Kero, and Tomoyo return to the forest, this time with Sakura wearing a very slick, futuristic, vocaloid-esque yellow costume. That’s two looks in the same episode for the first time! This time her mother beckons her to the cliff’s edge again, but Sakura snaps out of it, remembering Yukito’s words. Turns out it’s not the ghost of her mother, but a Clow Card called Illusion, which Sakura successfully captures.
The next morning, Sakura is ready to go back to school, but takes a moment to say hi to her mother, confident she’s not lonely by that cliff, but up in a beautiful place among the stars. Touya suddenly notices the real ghost of Nadeshiko appearing, however briefly, watching over Sakura and smiling.
This was the first truly heartstring-pulling episode of CCS, exploring how despite barely remembering her mother, she still loves her deeply due to the stories her dad and brother have told her, and in turn Nadeshiko is always watching over Sakura, no doubt immensely proud of her daughter’s new calling.
