You can get the blue stars through a game by of course, purchasing. You know, the purple button bellow with a shopping bag design. You can see the new cards, blue star and 4-colored cards.

Now I get your point about the summon, you can "purchase" 1 card or 11 cards with the yellow stars by pressing the green button below that has a photo design. 1 card costs 25 yellow stars total and 11 cards cost 250 yellow stars total. There's a chance that you get a SR or PR cards. But the chance is slim, especially the PR ones. Since there's a special "event", you know that you read SP as an abbreviation for special, you have a chance that you'll get a PR card.
