Draw Cards? Sorry for My Level is Sss

[Strong female lead + overpowered cheat system + gacha + summoning + magic + no male protagonist]

After Yu Youyi died of illness, she transmigrated to another world and lived there for seventeen years. This was a fantasy world where everyone would undergo an awakening summoning during their senior year of high school. During the summoning, each person would have three cards in front of them. Depending on their talent and potential, the summoner would draw different types of beasts. Yu Youyi always thought she didn't have any cheat codes, until she discovered that she was bound to a card-drawing system when she awakened... SSR Elf King, SSR Mermaid Princess, SSR Archangel, SSR Flame Dragon—she could draw them all with ease.
