In some yami and seto fanfictions, Yami might be depicted as the more mysterious and powerful one. Seto, on the other hand, is often shown as the proud and wealthy character. Their interactions can range from intense rivalries to unexpected alliances or even romantic undertones. However, in lemon fanfictions, these characteristics can sometimes be exaggerated for the sake of the plot.
Kaede Rukawa's novels did not have a clear official name or definition. Kaede Rukawa was usually referring to the father of a character in the Japanese manga Naruto, also known as Naruto Uzumaki. This character had a very important position in Japanese manga. He was a famous ninja in the Naruto world.
Maybe Seto is trying to understand Yugi better in order to outwit him in some future duel. He could be observing Yugi's mannerisms, strategies, and how he interacts with Yami, all to gain an edge.
Maybe Mokuba would be a crucial character. As Seto's brother, he would be deeply concerned about his brother's transformation. He could be the one staying by Seto's side the most, trying to comfort him and also helping the others figure out how to reverse the spell. Another character could be Kaiba's business rival who might see this as an opportunity to take over KaibaCorp, adding some conflict to the story.
Seto's usually cold and calculating personality might soften. He could start showing more vulnerability around Joey. For example, he might let Joey see him without his usual confident facade when they're alone. Joey, on the other hand, might become more responsible. His impulsive nature could be tempered as he realizes he has someone he really cares about in Seto.
Let me recommend you a doujinshi novel," The Hot-blooded Youth of Slam Dunk ", written by the author, Erbai Yingyue. The plot was about the story of Kaede Rukawa and Hanamichi Sakuragi. If you are a loyal fan of Slam Dunk, then you definitely won't miss this novel. I hope you like my recommendation.
