Martial Spirits are supernatural entities or powers that exist within individuals in certain fantasy settings, often associated with martial arts or combat. They can manifest as unique abilities, skills, or even physical forms that enhance a person's fighting capabilities. Each Martial Spirit is typically linked to the individual's personality, strengths, and experiences. In many stories, Martial Spirits can evolve or grow stronger as the individual trains and faces challenges. They may provide guidance, boost physical abilities, or grant special techniques. The bond between a person and their Martial Spirit is often central to the narrative, influencing character development and plot progression.
