DLsite allows you to register your product as a series.
Products that are part of a series will have a [ Serial List ] link to other products in the same series on their description page, making them easier to find.
Series settings can be altered via [ Manage Series ] on the Circle Management page.
Please note that each product can only be made part of 1 series.
When adding a new series, we will only confirm the name of the series; you can freely arrange what products are in the series.
