The mark(mole) that appeared on Kanroji Mitsuri was the symbol of her remarkable power-up.

Kanroji Mitsuri, one of the Hashira possessing top-tier abilities within the Demon Slayer Corps, exhibited a mark similar to that of the protagonist, Tanjiro. Let’s delve into the details of this occurrence.

※ Since many scenes not aired in the anime will be discussed further, those who dislike spoilers are advised to refrain from reading beyond this point.

What exactly is the mark(mole) that appeared on Kanroji?

The protagonist, Kamado Tanjiro, always has a distinctive mark on his forehead. Moreover, when he utilizes the “Hinokami Kagura Breathing” technique or faces certain situations, this mark expands.

And when the mark expands, Tanjiro can unleash power surpassing his usual state, even when fatigued. During a battle involving Kanroji, although not on her forehead like Tanjiro’s, a distinctive mark of a special shape appeared. It’s similar to what was described earlier!

Of course, this mark doesn’t appear under normal circumstances.

The mark emerged due to being pushed into a certain situation. Following this, Kanroji’s remarkable performance in battle left even the demons she fought against astounded. After this battle, there was a discussion about training all the Hashira to be able to manifest the mark. When asked about the state she was in when the mark actually appeared, Kanroji responded…

“It went ‘Guaaaahh!!’ My heart was pounding, and my ears were ringing loudly!! It was like ‘mekimeki’!!”

I guess that didn’t quite answer it, huh? (laughs) After this, there’s an explanation from Tomioka Giyuu, who has also had the mark appear, about the conditions nearly guaranteed to bring about the mark’s appearance. We’ve prepared another article about that, so please check it out!

Lastly

There’s still so much we don’t know about the marks in the main story. Eventually, we may see all the Hashira manifesting the mark, or perhaps there will be developments involving rebellion by the families with the mark. I’m looking forward to checking out these developments! Well, that’s it for now…
