In a world where mystical powers are bestowed upon those who cross into the spirit realm, Haru Takeda is a young warrior who has just completed his training. With his abilities to manipulate elemental forces, Haru is sent on a journey to retrieve a lost artifact that has the power to bring peace to warring kingdoms.

Along the way, Haru encounters Aiko, a charismatic rogue with a knack for finding hidden treasures, and Kojiro, a reserved but fiercely skilled swordsman. As they traverse dangerous landscapes and battle fearsome creatures, they form a close bond, realizing that they are stronger together than alone.

As the journey progresses, Haru finds himself attracted to both Aiko and Kojiro.

As they get closer to their goal, Haru discovers a dark secret about the artifact that could change the balance of power in their world. With both Aiko and Kojiro by his side, Haru must decide not only which path to take but also where his heart truly lies.
