Complex magic systems are not new in the vast world of anime, as many serve as backbones to the tales they belong to. From the Chakras in Naruto to the alchemy in Fullmetal Alchemist each of these anime presented its unique interpretation, weaving a tapestry of mysticism and lore. Hell's Paradise introduces its own nuanced magic system that has captivated fans of the anime yet remains shrouded in mystery. Tao, a concept inspired by Chinese philosophies, is a magic system that is interwoven with the fabric of energy and aura. In Hell's Paradise, it is brought to life through wave imagery and visualizations, which suggests a foundation that is rooted more in a person's frequency than mystical energy.
