Attack on Titan and Kimetsu no Yaiba are two anime series that have gained immense popularity due to their intriguing portrayals of the relationships between humans and non-humans. Both anime have elements of two different dimensions that coexist in a complex world.
Attack on Titan is about the Eldian people, who are descendants of Ymir Fritz. These people have the unique ability, or perhaps curse, of transforming into Titans. Titans are giants that were originally human beings, but they were transformed into Titans due to their Eldian blood. This power was inherited by the Eldians and has been passed down for generations, making them a unique race. Ymir is considered the founder of the Titans. However, the power of Titans was misused by the Eldians and led to a civil war among themselves. Pure Titans and Titan shifters, or half-human Titans, have their own vulnerabilities, but in general, their vulnerability is located on the nape of their neck.
Similarly, in the anime Kimetsu no Yaiba, demons possess a weakness in their neck. This vulnerability is generally their weakness, but it is not always the case. Specific demons such as Daki have unique conditions, a weakness in the neck but only if her brother, Gyutaro, was killed as well. Kimetsu no Yaiba is more mystical in nature and is set in classical Japan while Attack on Titan has a more modern feel to it, portrayed through various weapons used in their battles.
In conclusion, Attack on Titan and Kimetsu no Yaiba are two anime series that explore complex relations between humans and non-humans. While both may share a similarity in weaknesses found in the neck region, the two series differ in their overall approach to the mystic and modern worlds. These series continue to captivate audiences with their stunning visuals and compelling storylines that leave viewers on the edge of their seats.
