DADAN Inc. (Headquarters: Minato-ku, Tokyo, President and CEO: Keita Nakamura, a wholly-owned subsidiary of GREE Holdings, Inc., hereinafter "DADAN") has decided to provide its cloud tool "DEDEN" to Shueisha Inc. (Headquarters: Chiyoda-ku, Tokyo, President and CEO: Hideaki Hayashi, hereinafter "Shueisha").
This initiative aims to resolve campaign operation challenges for electronic comic stores and will promote the development of dedicated functions tailored to Shueisha's operations.
This announcement concerns the decision to undertake this initiative, and further details will be announced sequentially in future updates.
■ Background
With the expansion of the electronic comic market, publishers are required to manage bibliography and files, produce, submit/deliver, and operate promotional measures (campaigns, etc.) in accordance with diversified distribution formats and store requirements. On the other hand, the process from production to delivery and promotional operations involves many stakeholders and is an area where confirmations and rejections often occur, increasing the importance of standardizing and streamlining operations.
Shueisha faced challenges in streamlining campaign operations across multiple electronic comic stores, accumulating and visualizing related data, and improving processes including authorization work, requiring the establishment of a dedicated operational base that could address these issues.
DADAN has supported the optimization of operations related to electronic comics through its cloud tool "DEDEN," which supports the daily operations of publishers. This time, with the aim of further streamlining Shueisha's electronic comic-related operations and strengthening its operational structure, it has been decided to introduce the cloud tool "DEDEN" and develop dedicated functions specialized for Shueisha's operations.
■ Overview of Initiative
1. Decision to provide "DEDEN" for Shueisha
The provision of DEDEN will commence with the aim of streamlining campaign operations conducted at electronic comic stores, accumulating and visualizing related data, and simplifying authorization work. We plan to support the development of workflows suitable for operations and the standardization of management methods, focusing on business processes related to bibliography and file management. It should be noted that this provision does not include any generative AI-related functions.
2. Development of dedicated functions for Shueisha to streamline campaign operations
To further smooth the planning, preparation, and authorization of campaigns conducted at electronic comic stores, we will promote the development of dedicated functions tailored to Shueisha's operations. We plan to proceed with the organization of necessary functional requirements and phased implementation while taking into account the actual operational conditions on site.

〇 Easy file/bibliography management
With a simple and intuitive cloud-based interface, traditional complex bibliographic information and file management tasks become easy.
〇 Cheap and easy EPUB production + chapter splitting
Automated production functions allow for quick creation of EPUB and chapter-split files. Significant reductions in personnel and production costs are expected.
〇 Minimum effort for delivery
Automatically delivers produced and registered files to pre-designated delivery destinations. Bibliographic information is automatically converted to match the format of the delivery destination, significantly reducing manual work in delivery. It also supports automatic resizing of vertical manga and thumbnail generation.
〇 Consistent security
The cloud platform minimizes local work, maintaining a secure working environment. File viewing is also encrypted, reducing digital risks.
〇 Efficient in-house media development and operation
It can also be used as a CMS for in-house series and trial reading media. Since files are centrally managed, seamless operations from file production to serialization and bookstore distribution are possible. Operations are significantly streamlined.
〇 Regular updates
Updates are regularly carried out to provide more user-friendly services, taking into account customer feedback and new feature additions. A translation function is scheduled for release soon.
