In the age of Universal Awakening on the Azure Sphere, a myriad of races and gods coexist. 
Devils, dark gods, and monsters descend upon the mortal realm, only to be met by the Awakened.
Howard, during his Awakening Ritual, discovers dual talents— F-rank Mana Recovery, and the supreme talent: Supreme Synthesis. 
He keeps a low profile, hiding as a 'common magus.'
Through countless acts of synthesis, he forges supreme artifacts, supreme skills, and supreme classes! 
Fireball synthesis... Ding! Synthesis successful, attaining D-rank skill— Fire Serpent! 
Fire Serpent synthesis... Ding! Synthesis successful, attaining B-rank skill— Fire Python! 
Fire Python synthesis... Ding! Synthesis successful, attaining S-rank skill— Dragonfire!
When devils invade and dark gods descend, they are left slack-jawed by the Azure Sphere before them. 
"No, this is a trap... a trap disguised as a mere cupcake!"

Cotler argued, "What does it matter to us if Howard is defeated?"

Bismarck shook his head and replied, "Such sentiments should have been expressed before the war began. We, Phrus, are already committed to this fight. If Howard loses, are we to single-handedly withstand Manluk and Osland Kingdom? Though Phrus is capable in battle and might not necessarily lose, such a conflict would severely deplete our national strength. Cotler, you have two choices: lead a thousand men back, or stay here to command your troops and keep silent.

As time progressed, the siege of Constantinople Castle revealed its daunting challenge.

After a grueling two to three months, the fortress stood unyielding, its defenses seemingly impenetrable.

Alonso, assessing the situation, proposed to Howard a direct and forceful assault on the fortress.

The continuous siege was weakening Phrus's position, and he feared they might not hold much longer.
