"Long ago, there was a world inhabited by both humans and hybrid animals, and there were only eight remaining souls in existence up to that point. This world was protected by a team of heroes known as the Soulkeepers. Their mission was to ensure the safety and well-being of all people by shielding them from danger and malevolent forces.

One of the Soulkeepers had the soul of Love, who was a fusion of a human and a tanuki. She was known for her creativity and incredible ideas, but unfortunately, she was unable to venture out due to restrictions on her magical abilities. Despite this, all of the other Soulkeepers cherished.

One night, the Sk Love observed that the Sk Determination had developed feelings for her due to her captivating looks and endearing personality. Both of them longed to openly share their affection, but Sk Perseverance rejected the idea vehemently, insisting that their relationship would jeopardize their future hopes and dreams.

No matter how much the Sk Perseverance attempted to dissuade her, Love remained resolute and ignored his advice. The other Soulkeepers tried to intervene, suggesting that he should allow her to follow her heart, but he vehemently opposed them. His unwillingness to compromise ultimately led to even more dire consequences.

"One fateful day, the Sk Perseverance attempted to harm the Sk Determination, but Sk Love courageously stepped in to protect him, ultimately giving her life for his sake. This act of sacrifice opened the door for evil to enter this world, leading to the birth of hatred. The malevolent force spread, infecting people's hearts and souls, causing them to lose their ability to feel love. In its wake, nothing but pain and despair remained."

"As a consequence of his transgressions, the Sk Perseverance was stripped of his status as a Soulkeeper, facing banishment from the group. In his wrath, he vowed revenge against those he believed wronged him. However, the situation took an even darker turn when the remaining Soulkeepers mysteriously vanished without a trace. This development ignited conflict and prompted the implementation of new rules across various regions of the world in response to the prevailing chaos."

"Meanwhile, Sk Determination chose to compile various books on the history of races, timelines, and soul-based abilities as a way to preserve the memory of his love for the Soul of Love. He fervently hoped and wished for a better future, holding onto the belief that the world would eventually heal and find its way back to a state of love and peace."

"Every 15 years, a legendary entity known as the Spirit Whale would emerge into the sky, diligently collecting the souls of those who have passed on. The Whale would carefully gather these souls, carrying them into the afterlife while preserving their memories and experiences up to the very moment of their passing."

"Before Sk Love passing, she made a final wish to create a new soul, which she named "Passion". Her hope was that this new soul would help make the world better for those who came after her. Several years went by, a human hybrid with the soul of Passion was chosen to become the next Soulkeeper. This marked the beginning of a new chapter in the intertwined destinies of humans and hybrid animals."
