Also known as the Dimensional Infinity Fortress, the Infinity Castle is a prime hideout of Twelve Kizuki. In the Infinity Castle Arc, it will be the central location of the show.

In the later chapters of the manga, Gyukko and Hantengu also lose their battles, and Nezuko's resistance to the sun is revealed to Muzan. After this incident, Muzan gathers all the upper-rank demons to Infinity Castle and turns them into mindless lower-rank demons.

Infinity Castle is turned into dust during the fight between the Demon Slayers and Muzan. Nakime is the one whose Blood Demon Art controls the castle, but she gets manipulated by Yushiro. As a result, Muzan kills Yushiro, and the castle falls apart.

Only the upper-rank demons of the Twelve Kizuki are aware of the castle's existence. The lower rank demons have no idea about it, and neither have they ever been summoned there.
