Final answer:
The chapter focuses on the subculture of otaku, highlighting behaviors like cosplay and fan practices, which go beyond just the content of anime and manga.
Step-by-step explanation:
The focus of the chapter in question appears to address the subculture of otaku, which is more concerned with the behaviors, practices, and social implications related to fans of anime, manga, and similar media rather than the content of the media itself. Otaku is often characterized by a deep passion for Japanese anime and manga, and this passion can manifest in various ways, such as through cosplay, where individuals create and wear costumes to represent characters from their favorite series. An example of this can be seen in cosplayers who form subgroups to emulate characters from specific universes, such as those from DC Comics. The mention of manga and anime suggests an exploration of how these mediums influence the otaku subculture, while cosplayers, as highlighted in LibreTexts, showcase the diverse ways in which fans engage with and express their fandom.
