Kokushibo's unique ability to use a Breathing Style alongside his sword makes him a formidable opponent. The anticipation surrounding Infinity Castle Part Two is immense, as it is expected to feature one of the series' most thrilling battles. This film has not only captivated audiences but has also influenced the anime film landscape, prompting other series like Solo Leveling and Chainsaw Man to pursue theatrical releases.
