There were two reasons why Ishida Sansei refused to drink the water. First of all, some people thought that he refused to drink water because persimmons were prone to phlegm. He did not want to die with unclean things, and persimmons were not good for the body. Secondly, Ishida Sansei believed that ambitious people should cherish their bodies and be responsible for themselves even when they were on the verge of death. He refused to drink water to maintain his self-discipline and cherish himself. These two explanations reflected Ishida Mitsunari's characteristics and self-cultivation as an ambitious person.
Well, a Nishimiya x Ishida fanfiction often explores the relationship between these two characters. It could be about their friendship deepening into something more, like a romantic relationship. The fanfiction might focus on their interactions, how they understand each other's feelings, and the development of their bond over time.
I'm pretty sure Ishida doesn't have a niece in the manga. Usually, such significant family relations would be clearly shown or at least hinted at, but there's been no indication of this.
Ishida doesn't die. The manga follows a different trajectory for his character arc, emphasizing his personal development and relationships rather than a tragic end like death.
Matt could be a new superhero in the fanfic. Maybe he has some unique powers or abilities that haven't been seen before. He might be a street - level hero who has a different perspective compared to the Avengers.
Yamato might show his concern by constantly checking on Naruto's condition. He could be seen sitting by Naruto's bedside, feeling his forehead for fever regularly.
I'm not certain as the 'Matt Foley Christmas Story' isn't a well - known mainstream story. But generally, Matt Foley could be the main character, perhaps a local figure or just an ordinary person created for this particular story. He might be someone with a big heart, or a bit of a clumsy character who gets into all sorts of situations during Christmas.
It's also because of the strong bond they form in the original series. Fans are interested in seeing this bond developed further in different scenarios. For example, in fanfictions, they can be put in romantic situations or face new challenges together that the original story didn't cover. This gives fans a chance to see new sides of their relationship and characters.
