Resonance book 1:Chaos rising

Resonance
Six hundred years ago, the first Resonance user, Leon Yamamoto, defeated the God of Chaos, Chaon, and brought peace to the world. After Leon's death, his sister Aki Yamamoto inherited the throne. Over centuries, that peace slowly twisted into tyranny as Aki became an immortal ruler feared across the world.
In the present day, thirteen-year-old Kaien Walker, an ordinary boy from Havenport, discovers that he carries the bloodline of the legendary Yamamoto family and possesses the incredibly rare Cosmic Resonance. After enrolling under the legendary teacher Mr. Miyoto, Kaien meets allies including Sora, Ren, Elara, and others who become more than teammates. They become family.
As Kaien trains to master his Resonance and uncover the truth about his heritage, a growing darkness emerges. Rei, Miyoto's former student, embraces the forbidden Chaos Resonance, gathering powerful commanders and throwing the world into war. Ancient gods awaken, forgotten Sovereign Beasts return, kingdoms collapse, and secrets buried for centuries begin to surface.
Throughout the journey, Kaien faces enemies who challenge more than his strength. They test his compassion, leadership, and belief that people can change. He discovers that power alone cannot save the world. Every battle forces him to choose between revenge and mercy, destruction and hope.
As the conflict expands beyond humanity, Kaien learns that Resonance itself was created by Nagomi, the God of Balance, and that the fate of every Resonance user is connected to a much larger cosmic struggle. To end the cycle of chaos, Kaien must unite allies from every corner of the world, confront the immortal monarch Aki, overcome the darkness within himself, and face threats powerful enough to reshape reality itself.
In the end, Resonance is the story of a quiet boy who grows into the world's greatest protector, proving that true strength isn't measured by overwhelming power, but by the courage to protect others, and inspire hope,
