Passion may develop into immersion in a consumer activity. However, in the long term, it may translate into a search for belonging among those who share the same interest. Being a fan does not mean passive consumption; rather, this interest motivates consumers to participate [34] in spreading and influencing the market for the product. By combining participant online ethnography with 10 in-depth interviews, this study examines fans’ motivation to engage with technology that shapes their experiences. Focusing on Otaku culture in Tunisia and using an interdisciplinary framework, this paper explores the hidden motivations behind community belonging and interactions with globalized systems. The findings reveal the mechanisms of this journey, demonstrating how digital platforms are used to accumulate knowledge, skills, and networks to achieve membership, influence market trends, and glocalize transnational culture through earned authority. This research contributes to fandom literature by emphasizing the role of platforms in fostering belonging and engagement with institutional forces. Additionally, it offers businesses and entrepreneurs insights into fan behavior and their role in shaping new markets.
