Tensei; The Vengeful Spirit

A young woman awakened as a spirit of vengeance and longing. Her transformation after death was shrouded in mystery, leaving her with one burning question:

Why?

Born as the youngest daughter of a powerful vengeful spirit family, she should have been content with the legacy of her new existence. Yet, her heart ached with a desire far greater than vengeance.

She yearned for the truth of her past life.

Fragments of forgotten memories haunted her like whispers on the wind. A wish, unfulfilled in life, lingered in her soul. Perhaps beyond the shadowy confines of her home. The underworld of Tsukudo Shrine. She might uncover the answers she sought.

Or perhaps the ancient Edohigan tree, said to hold immeasurable power, could awaken the memories buried deep within her.
Four centuries passed, the yearning growing stronger with each fleeting year.

And then, one fateful night, she made a decision.

It would be her last night within the shrine's suffocating walls. The life she had known cold, repetitive, and stagnant would end.

She would leave behind the world of the dead to pursue the truth of the living.
