These Hashira are the highest-ranking swordsmen in the Demon Slayer Corps. As demons lurk in the shadows, a new battle commences for Tanjiro and his comrades.
Word Count Check: The synopsis is very short. I need to expand it to 160-220 words using only the provided info.
Wait, if the provided info is insufficient to reach 160 words without inventing details, I must be careful.
Problem: The synopsis provided is only about 50 words. The prompt requires a 160-220 word summary.
Constraint Check: "You write ONLY verifiable facts that are explicitly supported by the provided SYNOPSIS and SOURCES. You never invent or guess... If a detail is not in the provided material, you omit it rather than guess."
Conflict: The prompt asks for 160-220 words, but the source material is too sparse to reach that length
