It appears that Rudeus isn't the only wayward soul to have received power from the Demon God Laplace. In his effort to reincarnate into the future, Laplace's soul has imparted several of his characteristics onto your soul. Your soul isn't a perfect match for Laplace, so you have no need to worry about the Demon God assuming control of your body and place in life.
Your Laplace factors will impart an increased potential and capacity for magic and mana, respectively. While your growth rate in capacity will be highest while you're young, you find that so long as you continue to push your limits with magic, you will be able improve those very limits. As you grow to understand the effects of your magic and feel the flow of mana in your body, you will develop the ability to forgo the chants necessary to focus your spells.
You will find that you have increased strength and endurance. While this increase starts small, you will find a similar ability to push and grow past your physical limits.
Notably you lack the trait that would prevent you from forming and wearing a Battle Aura. You may optionally possess the trait of having green hair, which might instill some level of apprehension in others or arouse their bigotry if you ever find yourself in the Six-Faced World.
