■About the Company

The company is a startup striving to create a "Fan Nation"—a society where everyone can live life centered on their passions and obsessions. They operate one of the world's largest anime and manga community sites, develop and provide a fan community platform, and run a Web3 financial business.

They've also welcomed various publishers and entertainment-related companies as new shareholders, strengthening their collaboration with IP holders. The company is tackling the construction of the next social infrastructure by implementing cutting-edge technologies like blockchain and generative AI in the entertainment sector, an area in which Japan excels.

■About the Products and Business

The company's fan community platform works with entertainment companies (IP holders) to provide features and systems that strengthen fan connections and activities through official, exclusive content. To maximize fan engagement, the product integrates a wide array of functions, including posting, commenting, gaming, and an online store.

It features an extensive collection of work information, user reviews and ratings, personal viewing/reading history management, and vibrant forum discussions, making it an indispensable platform for global fans.
