This novel is heavily based on the geometry and the creation of geometric shapes. 
Every shape reflects a different spell. 
For example, the circle represents fire, while the square represents earth.
But there are countless elements beyond the basic ones, countless regular and irregular shapes, and many other things.

Geometric shapes of various types on the two-dimensional plane, the appearance and evolution of concepts on the three-dimensional plane, prisms, antiprisms, Archimedean solids.
But don't worry, it won't be too complicated. They are just shapes, after all.

Furthermore, the best things are the four-dimensional shapes!!

“Hey monster, you're not ready for this blow, but I don't give a shit!!” said Lian as he drew a giant circle in his mind.

Then, a few istant later, a fireball as big as a house hit a monster just over 4 meters tall... 
It was a waste of resources, but it was damn fun!

“BOOM!!!” he said as the fireball reached the monster, covering it entirely.

The excitement on his face was palpable as his clothes and hair fluttered from the power generated by the impact.

“Tsk, it's really hard to achieve 100% accuracy when casting spells... that just means I have to do better!”

Meanwhile, the monster and the entire area around him was destroyed. The crater was huge, flames burned the ground, and ash mixed with dust covered the air.

In a world full of Gates, Mages and Knights work together to defend humanity from extinction

Lian, a boy from a small town, awakens a very... unique system.
Casting spells by drawing strange shapes in his mind had become normal for him by now.
Thanks to the system, he had become a Mage, a human capable of using mana to cast spells. 

Facing monsters from the Gates had become routine. Studying magic was a pastime. After all, he had the System, he didn't need to study classical magic. Or maybe not...

Geometric Mage: First Spell, Circle

Damn it, why did I not think of that before?! She is right!

Lian had never used other arcane formulas for a simple reason: he did not need them. Yet, when he pronounced the formula, the power of the spell formed through the circle increased.

Lian closed his eyes, trying to recall what the other fire element spells were.

There was "Ignis Arde, Flamma Parva" to summon a companion fire, usable also in combat as a close-range weapon.

There was "Ignis Arde, Ignis Globus," Lian's favorite formula, which allowed him to launch a fireball.

Lian had never tried using another formula, simply because his system said the circle was for launching fireballs. It did not mention anything else about it.

However, now that he had reached 70% precision, he had unlocked variants. Perhaps now he could unleash more devastating attacks?
