Deathly Whispers: The voice that brings chaos

In a world known as Avalonia, there is an entity without physical form, that has sown chaos throughout all of civilization. How it operates and what its end goals are, is a mystery to anyone. One day this entity would choose Naoki Rhein as its next play thing. It granted Naoki powers that he could only dream of.
This occurrence, however, would attract all kinds of nefarious people down his path, leading to death and destruction of what he holds dear. His goal is to stop those people from doing exactly that.
Not long after being granted powers, he would meet the teacher Yasmin, who had her own history with the unknown entity. This entity had caused her great grievances throughout her past and because of that, she will assist him in stopping the chaos that's affecting everyone around Naoki.
During their journeys, they would discover the true nature of the unknown entity and what it had done in the past. Their discoveries would lead them towards unveiling the oldest mysteries of their world.
