Figuring out which manga chapter the Demon Slayer anime is on can be tricky. The anime might combine or reorder elements from different manga chapters to create a coherent and engaging viewing experience. That's why it's not as straightforward to match them one-to-one.
The anime adaptation of Demon Slayer doesn't follow the manga chapters in a straightforward manner. There are often adjustments and condensations for better storytelling in the animated format. So, it's not simple to say which specific chapter it's on.
