In the quiet town of Velton, where the wind whispers secrets and shadows stretch longer than they should, a chance encounter sets Kai on a path that will change his destiny forever. It all begins with a simple bonsai that falls from the sky, revealing a hidden mystery beneath the soil: a photograph of a woman who appears otherworldly. This image sparks a chain of events that pulls him into an abyss where dreams and reality blur, and the truth is not always what it seems.

Kai meets Oda, an enigmatic young woman who seems to have literally fallen from the sky. Her eyes, like stormy skies, and her fleeting smile captivate Kai's heart, making him question everything he once believed. Together, they embark on a journey beyond the known world, into the heart of a forest that holds ancient secrets, governed by a colossal cherry tree whose roots seem to reach into another realm.

But this is no fairy tale. The forest is a battleground between angels and demons, where lost souls wander, seeking either redemption or revenge. Amid the whispers of ancient spells and the ominous presence of creatures like the Escalius and the soul-devouring Fandal, Kai and Oda must face trials that will test their humanity and their will to survive.

"The Angel of the Tree" is a story where the ethereal meets the earthly, where love and sacrifice intertwine like roots in the darkness. As Kai delves deeper into this shadowy, dream-like world, he uncovers a secret that Oda has been keeping—one that could destroy them both. Will Kai unravel the mysteries of this otherworldly realm and save his Angel of the Tree, or will he be lost forever in the crossroads between two realities?
