Cosy Hell

You have to open the image in a tab/download it and zoom in to read it, sorry!! I couldn't figure out how to vectorise the text :(

The original tumblr upload in Japanese is here, the sheet itself links to a deleted pixiv site so I have no idea where it was originally from, but it definitely seems to be written by Oda

Please let me know if there are any errors!!

I'm not Japanese nor do I speak/read it, I just used google translate + a lot of googling and wikipedia to look up japanese sword terminology. I can also read kanji so that helped a bit

Some other random notes if you'd like to reference the original post:
