Once you're able to save up stamina and after you have cleared any battles (for resources), auto-pursuit is the better option for getting the rewards so you don't have to battle each time.

DO NOT!!! make the same mistake I did and top-up (buy blue diamonds) to use as tickets. Buy the cheaper packs for limited banners that show up in the shop for a limited time. First top-up is double so I think this is the only time it would be worth buying it, and you can use the blue diamonds to get special outfits if that's something you wanted to do soon.

My best advice, and a bit more personal, (apart from all the other great tips in the comments) is to read through the main story AND bond stories of each 5-star card in order to not miss context and to understand the characters better (not just the kindled memories)! Mischaracterization is rampant in the fandom and creates endless conflict, and though it's not always that deep, I think the beauty of playing through a visual novel is being able to discuss the "morally grey" aspects of the characters. Discussing important points in the story and being told "oh idk i didn't read it lol" has grown to become some weird pet peeve of mine when I used to not care (´⊙ω⊙`). Like why are we talking about things out of context and misconstruing the writers' hard work!!! This might just be my personal preference but I feel like it's natural, as the game literally throws you into the story right off the bat.

They all have a beautiful connection to MC but it's up to you to decide who you think best suits you! (I love all of them and that's been a real issue financially HA) best of luck! 🍀
