Fanfiction about Tanjiro getting sick: What could be the plot?

Maybe it could be about how Smithers' sickness affects his work at the nuclear plant. For example, Mr. Burns might struggle to function without Smithers' efficient assistance, leading to some comical situations at the workplace.

Perhaps in the fanfiction, Tobirama's sickness makes him weak and he starts to reflect on his life and the choices he has made. He could have conversations with his loved ones where he reveals his regrets or hopes. This introspective side of him due to the sickness could add depth to his character. Also, his sickness might be a catalyst for changes in the village he has helped build, as others step up in his absence.

In fanfiction, Katniss might get sick due to exposure to new and dangerous toxins in the post - Hunger Games world. Maybe she's exploring uncharted areas and breathes in something harmful.

One possible plot twist could be that Tanjiro has to sacrifice a part of his own power to save Rengoku. Maybe he has to give up some of his newly acquired breathing techniques which he has worked so hard to master. This would show his selfless nature and his deep respect for Rengoku.

Well, often in these types of fanfictions, there's a sense of worry among the Autobot team. Bumblebee being sick might disrupt their missions or plans. So, they start to recall any strange incidents that could have led to his illness. There may also be a sub - plot where the Decepticons try to take advantage of Bumblebee's weakened state. And Bumblebee himself might have some flashbacks or memories during his sick time, which could give insights into his past or his relationship with other characters.

Well, in some fanfictions, it could be because of a curse or a jinx that was unknowingly placed on him before he arrived at the Burrow. The Burrow is not always a completely safe place, and with all the comings and goings of wizards and witches, someone with ill intentions could have targeted Harry. Also, he might have eaten something that didn't agree with him. The Weasley family's cooking, while delicious most of the time, could have used some ingredients that Harry's body wasn't used to.

The Hashiras would likely show concern. Some, like Shinobu, would immediately start looking into possible medical solutions. Giyuu might be more reserved in his worry but would still keep a close eye on Tanjiro. The other demon slayers would also be affected. They look up to Tanjiro, so his sickness would lower the morale of the group. They would try to support each other while waiting for Tanjiro to recover.

One common plot element could be the other turtles rallying around Mikey. They might try to find a cure or take care of him. For example, Donnie could use his scientific knowledge to diagnose Mikey. Another element could be Mikey's own struggle with being sick. He might feel weak and frustrated that he can't do his normal activities. Also, there could be a threat that takes advantage of Mikey's weakened state, like an enemy planning an attack while he's down.

In the fanfiction, one possible cause could be that he ate some bad leaves. Maybe the leaves were contaminated with some kind of toxin from a nearby factory. Another cause could be that he caught a strange virus from an animal that recently visited the zoo.

Perhaps he was poisoned. Given the dangerous situations he often gets into, someone could have slipped a poison into his food or drink. It might be a poison that is designed to specifically target demigods like him. Or, it could be related to his heritage. Since he is a demigod, there could be some genetic factor that makes him more susceptible to certain types of sickness, and in the fanfiction, this could be explored as he gets sick.
