Yusuke would likely become more withdrawn. He was always a bit of a rough - around - the - edges character, but Keiko's death would make him more somber. He might lose his sense of humor that he sometimes showed around her.
One possible plot could be that Keiko is caught in the crossfire of a demon battle that Yusuke is involved in. Yusuke, being a spirit detective, has many enemies. Maybe a powerful demon targets Keiko to get back at Yusuke. After her death, Yusuke could go into a deep state of despair and vow revenge. He might journey to the spirit world to find a way to bring her back, facing numerous challenges along the way.
To write this fanfic, you need to understand the characters well. Yusuke is tough on the outside but has a soft heart. Keiko is strong - willed and intelligent. Use these traits in the story. For instance, when they face difficulties during the pregnancy, Yusuke might want to solve them with his fists at first, but Keiko would remind him to think rationally. Also, add some cute moments, like Yusuke feeling the baby kick for the first time.
One idea could be that they struggle at first with the news of Keiko being pregnant. Yusuke, being his impulsive self, might initially panic but then quickly step up to support Keiko. He could start taking odd jobs to save money for the baby. Keiko, on the other hand, would be the calm and organized one, preparing for the baby's arrival by reading all the parenting books she can find.
In Yu Yu Hakusho lemon fanfiction, the relationship between Yusuke and Keiko can be quite diverse. Sometimes it delves deeper into their emotional connection, showing a more passionate side of their bond that might not be as fully explored in the original series. It could involve scenarios where they face new challenges together and their relationship grows stronger through those experiences.
One common theme is the exploration of their hidden desires. Since the 'lemon' aspect often implies a more sensual side, it could be about Yusuke and Keiko exploring their physical attraction that they may have suppressed in the original story. Another theme could be the intensification of their emotional bond. Through various situations in the fanfiction, their love and understanding for each other can grow deeper.
If Karasa kidnaps Keiko in a fanfiction, the story could go in many directions. For instance, Keiko might turn out to be much stronger than Karasa expected. She could use her wits and any special abilities she has to try and escape. Or perhaps there are other characters who will come to Keiko's rescue. They could be friends, family, or even strangers who happen to be in the right place at the right time.

Another plotline might involve Karasu having a personal vendetta against Keiko or someone close to her. He kidnaps her to exact revenge in a more elaborate and drawn - out way. This could lead to a series of events where Keiko tries to outwit Karasu and escape while also uncovering the true reasons behind his actions. And during this process, there could be unexpected alliances and betrayals.
Well, if Keiko is a person, it could be a biographical story that delves into aspects of his life that have been overlooked or not previously shared. It might cover his early years, his achievements, and the challenges he faced. Maybe it also includes interviews with people who knew him well, providing a more in - depth and personal look into his story.
