[DeepL Translation - needs review] The Book of Creation was in the possession of Kaldorah, the goddess of creation. The fragments that were shattered in the war of the gods were called "chaldees," and those who could make full use of the power hidden in the chaldees were called scepters. A young girl named Artie, who wanted to be loved by her father, lied and studied in the temple as a scepter candidate. When a transfer student, a boy named Ryeron, arrives at her doorstep, the wheels of fate...
Orthodox fantasy about magic users fighting over the fate of the world. I really liked the beginning, but can't say I found the magic school stuff as interesting. Still good - might bump to 4 stars if the second book pans out well.
The magic system works like those trading card kids anime where monsters with magical abilities are summoned from cards to fight. Really you could probably adapt the whole thing to a kids' anime pretty easily - it's pretty black and white with the villains/good guys. It's well told though.
Edit: Apparently it's a spinoff from a card battler video game called カルドセプト, which explains a lot.
Difficulty-wise, should be pretty easy if you're comfortable with the genre.
