A form of energy that can be traced back to the Big Bang allowing a vast variety of superhuman abilities, starting from enhancing physical abilities, with potential to reach levels best described as ascension. You start out with the same sensitivity and skill with Cosmo as a Bronze Saint, sufficient to destroy an entire island and throw punches fast enough to break the sound barrier, in addition to a Bronze Cloth of your choosing. With training, you may increase your sensitivity to and skill with Cosmos.
You should know that to reach higher levels with Cosmo, you should focus on developing senses beyond the five human senses of sight, hearing, taste, touch, and smell, totaling 9 senses to reach the Ultimate Cosmo. The 6th sense you will have already achieved as a user of Cosmo, Intuition, the 7th sense being Miraculosity which could be described as bringing about what can be considered impossible involving acts that go against nature like moving as fast as light, the 8th sense being Arayashiki which is connected into dead consciousness, requiring you to burn your Cosmo to your limits upon your death to achieve it, surpassing the cycle of life and death and reaching the first steps of divinity in the process, and the ninth sense of Divinity, reached through enlightenment.
