Inosuke doesn't become a Hashira in the manga. The story progresses with him having other significant experiences and achievements instead of achieving that specific position.
It's hard to give an exact number. Different story arcs and battles led to the deaths of multiple hashira. Some died heroically, while others met their fate in unexpected ways. The count changes as the manga progresses.
Definitely not. Genya remains outside the ranks of Hashira throughout the manga. This is because of a combination of factors such as his skills, experiences, and the overall direction of the story.
One scary story could be about Funneh and the Krew entering a haunted mansion in Roblox. They start to hear strange noises, like creaking floors and whispering voices. As they explore further, they find rooms filled with dark shadows that seem to move on their own. The atmosphere gets really tense, and they feel like they're being watched all the time.
One of the scariest moments could be when they are suddenly surrounded by a horde of menacing creatures in a dark forest in Roblox. The creatures are growling and closing in on them, and they have very little time to think of a way to escape.
