Kimetsu no Yaiba: Why does Yoriichi Tsugikuni appear at the end of Chapter 1 Season 3?

The anime of “Kimetsu no Yaiba“returned to Spain yesterday through the first episode of the third season of the anime, a special episode that the general public had been waiting for many months (maybe not so much if you went to the cinema like me to see the film Rumbo has the Blacksmiths Village, but still). Among everything that happened in this first extended episode, there was something particularly striking: the presence of Yoriichi Tsugikuni at the end of the chapter..

The Kimetsu no Yaiba anime changes an interesting element regarding the manga (SPOILERS)

For this reason, I want to discuss now who the aforementioned character is and why, in fact, his participation occurred at a time in the anime in which it is possible that many do not remember it in the manga, and for good reason:

• I remember at the time going to the cinema to see Rumbo a la Aldea de los Herreros with a group of friends and being amazed for the character that we saw at the very end of what would be the first chapter of season 3: Yoriichi.
• In effect, the creator of the breath of the sun, the nightmare of Muzanappeared in The Last Thing Tanjiro Saw and, in fact, The Last Thing the movie Kimetsu no Yaiba also showed us: Heading to the Blacksmith Village.
• It was a single moment: Yoriichi appeared next to Tokito while arguing with a member of the Blacksmith Village.. There was no word, action or anything like that: just a presence. However, said presence is one that originally does NOT occur in the mangaas you can see below:

• At the time, it was hard to explain as it was ONLY seen in the movie, but now that the chapter has been released publicly as such, it’s clear: ufotable has decided to modify a very interesting element of the story of Kimetsu no Yaiba.
• Why was it decided to introduce this in the Kimetsu no Yaiba anime? What is certain is that Soon, secrets such as the Mark of the Hunter, the Breath of the Sun and all its derivatives, the Transparent World will begin to unfold at full speed… this is all something that has Yoriichi as the central character, and while at this point in the story Tanjiro has already unknowingly used the mark, Tokito is the mainstay with the most potential of all (apart from being a descendant of Yoriichi himself, who would have encouraged the decision to introduce it with this specific individual and not another).
• In essence, I understand that if the Kimetsu no Yaiba anime wanted to put Yoriichi in this place and time, it’s to hint that the relevance of his figure is about to skyrocket.
