<p>In the season 4 Hashira training arc, Amane Ubuyashiki tells all the Hashira about the marks. It is the first known mention of the phrase &quot;demon slayer mark&quot; in the anime.</p>

<p> It’s also why the Hashira training happens - the Hashira want to develop the mark due to the advantages it offers after learning it is only accessible during incredible physical exertion. AKA, the bulging veins and eyes from Tanjiro we’ve come to love.</p>

<p>In <em>Demon Slayer</em> anime until the Entertainment District arc, I believed that only Tanjiro can have marks, but in the Swordsmith Village anime arc, it is shown that both Muichiro and Mitsuri get demon slayer marks. However, in anime, it's not explained about the marks.</p>
<p>So, in which arc the marks will be explained?</p>

In *Demon Slayer* anime until the Entertainment District arc, I believed that only Tanjiro can have marks, but in the Swordsmith Village anime arc, it is shown that both Muichiro and Mitsuri get demon slayer marks. However, in anime, it's not explained about the marks.

So, in which arc the marks will be explained?
