Creativity also pops up a lot. Tomoyo's creative ways of documenting Sakura's adventures and making costumes are frequently highlighted. It gives a unique touch to the fanfictions. And of course, the theme of magic is always present as it's an integral part of the Cardcaptor Sakura world and affects their relationship in different ways in the fics.
One great 'Cardcaptor Sakura and Tomoyo fanfiction' is 'The Unseen Bond'. It beautifully explores their deep friendship. In this fic, Tomoyo uses her skills to help Sakura in new and creative ways during her card - capturing adventures.
Tomoyo and Eriol's relationship might develop when Eriol starts to notice Tomoyo's unique skills. For example, her talent for creating costumes could be useful in some magical ceremonies or events. Eriol could ask Tomoyo for help, and in the process, they would get to know each other better. As they collaborate on these projects, they would start to trust and rely on each other more, which would strengthen their relationship.
One great plot could be that Tomoyo discovers Eriol has a secret power related to the Clow Cards that even Sakura doesn't know about. Tomoyo, being the curious and supportive friend she is, decides to help Eriol understand this power better. They embark on a journey of discovery together, exploring old magic texts and hidden places in Tomoeda. Along the way, they face some minor magical mishaps that only strengthen their bond as they work through them.
In some fanfictions, Sakura might be portrayed as more bold or experimental due to the 'lemon' aspect. Tomoyo, on the other hand, could be shown as being more supportive or perhaps a bit more mischievous. But it really depends on the author's interpretation.
A fanfiction could focus on Sakura and Syaoran's daily life after the main events of Cardcaptor Sakura. Maybe they are training new cardcaptors. They could be facing challenges like how to teach the newbies about the importance of the cards and the right way to use their magic, all while their relationship continues to develop in this new phase of their lives.
It depends on how it's written, but generally, it doesn't seem appropriate. Cardcaptor Sakura is a story that is centered around positive values like friendship and courage. A 'diaper fanfic' might involve elements that are not in line with these values or are simply too odd and not suitable for the mainstream audience that the original series targets. If it's just a silly, innocent take on the characters in a different situation, it might be okay for a very small and specific group, but overall it's not a typical or appropriate addition to the Cardcaptor Sakura fan works.
The best sakura tomoyo fanfics are those that capture the essence of their relationship. They should have a good balance between dialogue and description. The dialogue should be natural, like how real friends would talk. The description, on the other hand, should be vivid enough to make the readers feel as if they are part of the story. For instance, when describing the settings where Sakura and Tomoyo interact, it should be detailed so that the readers can easily visualize the scene.
