Am I going to miss out on anything if I haven't played the games before this one?

[MACZ2021]

The only Summon Night games I've played so far were Swordcraft Story 1 and 2 and to my knowledge the SS games are in spinoff teritory so I would imagine they don't have much impact on the main games.

With that said, is there any need to play Summon Night 1-5 before playing 6 or, can I go into this one without having played the any of the games before it (besides spinoffs)? I'm currently waiting for the Wonderful Edition to ship and I saw an email was sent to me a little over a week ago saying the game should be shipped out in around the beginning of March so until then I just have to wait :/
