The story is great. You managed in incorporate the entire prompt into the story, got straight to the point of the story, and brought in elements of cannon in My Hero Academia, I really enjoyed it. If you don't mind, I'd like to offer some friendly advice.

1. You split the story into 3 parts, which isn't bad, but is unnecessary. I'm certain the amount in the three posts would have fit into a single one. I can only assume you were either afraid of losing the story when posting it, (a pain I know all too well), or you wrote it on a phone. It will probably be easier to just copy the work and paste it somewhere else to act as a backup if you're worried. Google docs, Word, I've even pasted into search engines before.

2. Please don't feel rushed to make a story for a prompt. You posted that story impressively quick, while managing to still make a good piece, but you don't need to hurry. It's not often that a story prompt is quickly taken, and if it's about wanting your prompt taken, then I understand but it might still take time for that to happen.

3. I personally constantly reread the story as I'm writing it, and when it's done, I go over it once or twice more. This helps me find mistakes, get rid of elements that I think interfere with the story, add new elements that I think will make the story better, and overall make it easier and more entertaining to read. I'm not saying you should or that you don't already, this is just a piece of knowledge that has helped me when writing.

I'm sorry if this comes across as condescending or rude, I just want to offer some advice I think could be helpful. I enjoy writing stories for these prompts, and I enjoy seeing what others make of my prompts.

P.S. I wish I knew about the sentient Noose; that would have been fun to add.
