Add to series

[Eule]

Dear Librarians,
I got an arc to an excisting French comic series. It collects the final three installments out of a final number of six and I have no idea how to add them.

Here is the series:

Here is the book I got on the publisher's page:
https://www.darkhorse.com/Books/3008-...

Here is the first Englisch-language bind-up on the publisher's page with the first three chapters:

Please add it to the series in a way that makes sense to the database because I am not sure I can. Thank you!

Done.
