Open a *.melon file from MelonBooks.co.jp

[qhz]

I recently downloaded an ebook from MelonBooks (not *.com), and have no way of opening it. I'm sure I need some dedicated program to open it, but I don't know how to get it. I've been searching through the links at the bottom of the mainpage but I can't find information about it.

If you know what I need to open the file, please link the page to download the program.

Edit: nevermind, I found it
