It is an application that anyone can easily post and view their own books and douujinshi samples for free.

I made a douujinshi, but I want to show you a sample magazine and an article before the event!
I made my own book, but I don't know how to show it to everyone!

It is an application that aims to let everyone see the books and douujinshi sample magazines produced by.

I made an app that can be used when you want to upload a part of the douujinshi that will be published as a new issue before the douujin event and show the contents.

If you download the app and log in (sign up), you can see the book immediately, so you can easily see the sample magazine.
You can also output a shortcut link for the book you uploaded with the QR code, so you can easily find the book you want to show.
