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!"

The terrifying potential of Regeneration instantly drew expressions of shock from both Howard and Tana.

Tana exclaimed in amazement, "Such a skill book would typically only be found on Legendary-grade BOSS, or even Epic-grade BOSS. Your luck is incredible, managing to obtain it so quickly!"

Seeing Howard still in a daze, Tana urged him again, "What are you standing around for? Use it quickly."

Jolted by her prompt, Howard snapped to his senses and immediately learned Regeneration.

"Diamond-grade BOSS really do provide generous rewards," Howard mused. "I owe a lot to you this time, mentor. If you hadn't brought me here, I wouldn't have reaped such rewards."

After smoothly flattering Tana, Howard continued to inspect the attributes of the shield.
