The first hour-long first episode of Kimetsu No Yaiba season 3 was released on April 9, along with the debut of a new opening theme song. But it seems that this new theme song does not match the content of the 3rd movie, a lot of criticism has surfaced on social networks.
The content of Kimetsu no Yaiba season 3 will focus on the story of the Blacksmith Village War. At the Swordsmithing Village, Tanjirou met the Charming Pillar Mitsuri Kanroji and Ha Tru Tokitou Muichirou. He attends training and finds an ancient sword.
After the defeat of Upper Huyen Luc, Muzan sent two other demons to search for information. Thanks to special blood demonic magic, they found the village of Swordsmithing and planned to attack this place. So, Tanjirou and the group encountered Hantengu – a multi-personality demon that can clone to fight, and Upper Xuan Ngu Gyokko – a demon who likes to use human corpses to create “works of art”.
Kimetsu no Yaiba season 3’s opening song is called “Kizuna no Kiseki”, performed by rock band MAN WITH A MISSION in collaboration with singer Milet. This is a powerful and refreshing song. Unfortunately, this song has received a lot of criticism on social networks, such as: “I don’t really like this new song”, “LiSA and Aimer are so good, I don’t understand why they changed”, “Although I want to force myself to like this song, it’s really boring”, “The song doesn’t suit Kimetsu no Yaiba at all”, “If it were a sports anime, maybe it would be suitable”.
Kimetsu no Yaiba is such a popular franchise that it has the potential to boost the careers of the artists involved. Perhaps because of that, the producer was wrong to think that “any song will be well received just because it appears in Kimetsu no Yaiba”. But reality is not what they think.
Also, the viewership ratings for the first episode of this third season were 8% in the Kanto region. At its peak, some episodes of “Kimetsu no Yaiba” easily surpassed 10% of viewership and even reached close to 20%. Perhaps interest in this franchise is dwindling, or it simply gets less interest because thousands of people have seen the film in theaters.
