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

Unlike fire, which exploded without issue and required no control, earth spells demanded active control. Lian had discovered this when he summoned the stone block as a shield. It required mana to maintain its active form.

Shaking his head and giving himself a light slap on the face, Freddy charged toward the impaled monster, his resolve hardened by the opportunity Lian had created.

His legs moved in a precise pattern as his hands gripped the greatsword. The runes on it glowed with brilliant green, a sign that whatever attack Freddy was about to unleash would be powerful.

But just as Freddy began to approach the monster, Lian lost control of the spell.

The stone spike that had pierced the worm vanished into blue particles, dissolving like a fleeting illusion, as the monster regained its freedom. A powerful roar shook the air, and the blood coagulated, ready to return to its body to heal the wound.
