Reiryoku, or "spiritual energy," is a concept often found in Japanese culture, particularly in anime and manga. It refers to the life force or energy that exists within all living beings. This energy can be harnessed for various purposes, such as enhancing physical abilities, performing spiritual practices, or engaging in combat. In many stories, characters can manipulate their Reiryoku to unleash powerful techniques or abilities. This energy is often depicted as a glowing aura surrounding individuals, signifying their strength and emotional state. Understanding and controlling Reiryoku is essential for characters who seek to grow stronger or protect others.
