So I beat all the 5 normal stages (unlock hyper mode)... is it time for me to get DLC?

or should I play around with the base game more until getting the dlc? thanks!

Have you unlocked the weapon "greatest jubilee?" Because that is the reward for beating the main game. If not then you have quite a bit more to do.

I waited until I beat the main game to do the DLC but I had the first one before that (I believe 100% the main game right before Foscari dropped if I remember correctly). The stuff from the DLCs don't show up in the main game until you unlock them from playing in the DLC levels so you can just ignore them until you beat the final boss like I did.
