In the Demon Slayer manga, Inosuke survives. The story doesn't have his character meet a fatal end. He plays an important role throughout and remains alive at the conclusion.
One great Inosuke Demon Slayer crossover fanfiction is the one where he crosses over with characters from another popular anime like 'My Hero Academia'. It's really interesting to see how his wild and brash personality clashes with the more civilized UA students. He could be put in a situation where he has to work with them to defeat a common enemy that combines the quirks from 'My Hero Academia' and the demons from 'Demon Slayer'.
One of the most creative plots is a crossover where Inosuke enters a virtual reality game world. He doesn't understand the concept of the game at first and just starts attacking everything he sees as if it were a demon. As the story progresses, he has to learn the rules of the game world and team up with other players. It's a fun and unique take on his character as he adapts to this digital realm.
Inosuke survives throughout the manga. The story doesn't have his death as part of the plot. His character remains active and plays a significant role until the end.
First, you need to understand Inosuke's character really well. Know his strengths like his amazing physical abilities and his weaknesses like his lack of social graces. Then, choose the world you want to cross him over with. For example, if it's a fantasy world, figure out how his abilities would work there.
Well, Inosuke's origin story is quite interesting. He was found in the mountains as a baby and was raised by a family of boars. This led to his rather unorthodox and savage behavior. He didn't have any proper human upbringing which is why he often acts on his instincts. For example, he is very aggressive in battles and doesn't really follow the normal social norms that other characters do. His origin also influenced his unique fighting style which is very much based on brute force and his animal - like agility.
