This unique aspect of his soul grants him immunity to the curse placed on Orsted, which induces hatred and fear towards the Dragon God in all beings born in Six-Faced World.

Unlike most individuals with the Laplace Factor, Rainhart has the ability to effectively utilize Battle Aura to reinforce his body without encountering any difficulties.

Heavenly Eyes

 * The Heavenly Eyes are a unique set of Demon Eyes that allow the resolution of a desired outcome as "inevitable", by way of committing the entirety of Rainhart's existence to the act of achieving the outcome. A power to take all the “measures for the sake of achieving an objective” and “narrowing them down to one”. It's an extremely unique set of demon eyes that confines naturally infinite potential futures into “just a single” outcome. The Heavenly Eyes come with a double-edged sword, demanding Reinhart to dedicate his entire existence and focus to achieve the predetermined outcome, leaving no room for doubt or hesitation.

Swordsmanship

 * Rainhart is an immensely skilled swordsman who excels in dual-wielding swords, parrying incoming attacks and retaliating from the opponent's blind side. Similar to his father, Rainhart is proficient in the all three major schools of swordsmanship and fights by using the North God Style to get close to his opponent, the Sword God Style to strike with precise and powerful attacks, and the Water God Style to defend while seeking opportunities to launch his own decisive strikes. Rainhart is skilled enough to utilize most sword techniques, even the Longsword of Light, with his bare hands.

Sword God Style

 * The Sword God Style is a style of swordsmanship that emphasizes speed and aggression, where the main focus is to strike down the opponent first. Given the philosophy of defeating the enemy with a single blow, this style usually renders its users inept at defense and leaving with no counter-attacks.

North God Style

 * The North God Style is a style of swordsmanship that includes non-sword fighting techniques such as first-aid and tracking, as well as the ability to fight while physically deficient. It relies heavily on the practitioner's adaptability and usage of one's surroundings. As a result, this style involves using a lot of tricks instead of refined techniques. Trained in the North God Style to at least Emperor rank, Rainhart are skilled enough to be a candidate for the North God rank.

Battle Aura

 * The Battle Aura is a technique that enhances an individual's physical capabilities to their utmost limits. It is a form of mana manipulation that focuses on empowering the body rather than invoking flashy magical effects. By channeling mana, the user can create a dense mantle of energy that covers their entire body or specific body parts. This invisible Battle Aura serves to explosively boost their physical power and physical defense, making their attacks stronger and providing a layer of protection in combat.

Dragon Saint Battle Aura

 * The Dragon Saint Battle Aura is a fighting style created by the Dragon God Urupen. This style emphasizes the efficient use of mana and is particularly renowned for its incredible defensive power. With Dragon Saint Battle Aura, Rainhart can utilize mana in a highly efficient manner. This allows him to execute powerful techniques while minimizing mana consumption, enabling him to engage in prolonged battles without quickly depleting his mana capacity. The defensive capabilities of Dragon Saint Battle Aura are exceptional, making it difficult for all but the most potent attacks to leave an effect on Rainhart.

Battle Aura Burst

 * The Battle Aura Burst is a mana manipulation technique that involves infusing one's weapons and body with Battle Aura and instantly expelling it, resulting in a temporary amplification of the user's abilities and attacks. This technique allows Rainhart to recreate the effect of a jet burst by expending a significant amount of mana. However, due to the high consumption of mana, the activation of Battle Aura Burst is usually temporary, as using it for extended periods could lead to the complete depletion of Rainhart's mana capacity.

Sphere Bondary

 * The Sphere Boundary is technique that combines elements of meditation, perception, and the manipulation of mana. It allows practitioners to perceive and adjust their immediate environment, minimizing their presence and making themselves effectively invisible. The ultimate goal of this technique is to achieve a state of oneness with the world, where the practitioner's human figure becomes naturally indiscernible.

Bloodlust Release Technique

 * The Bloodlust Release is a high-level Superd technique that Ruijerd taught Rainhart to unleash his bloodlust or killing intent. By utilizing this technique, Rainhart is able to exude a powerful aura of aggression and hostility, which can intimidate and provoke fear in his opponents. The release of his bloodlust makes his adversaries perceive him as a fearsome and dangerous presence, evoking a sense of encountering a monstrous being.

Presence Search Technique

 * The Presence Search is a high-level Superd technique taught by Ruijerd that enables Rainhart to sense the presence of others. By remaining still and focusing his senses, Rainhart can perceive various stimuli, including sounds, his surroundings, and even the flow of Mana. This heightened perception allows him to detect the presence of individuals, even from a distance. Through consistent practice, Rainhart has honed her ability to the point where he can pick up faint sounds, such as the clash of weapons, happening far away.

Magic

 * Rainhart is capable of casting magic simultaneously in both hands as well as cast melded magic in an instant. With his scientific knowledge from his previous life and creativity, he always strives for developing more efficient magics for himself to use. Despite this, Rainhart's talent in magic is considered only above average, as, unlike his Rudeus and Sylphy, he does not have an aptitude for all forms of magic, a trait that most people born with Laplace Factor possess.

Voiceless Incantation

 * The Voiceless Incantation refers to a unique form of spell-casting where the caster is able to perform magic without the need for verbal incantations or spoken words. It is a method of casting magic spells solely through the manipulation of mana and the caster's focused willpower. Instead of relying on the traditional method of reciting specific incantations or magic spells, a mage practicing Voiceless Incantation can channel their mana directly, visualizing the desired magic spell or effect in their mind. By mentally picturing the desired outcome and concentrating their mana accordingly, they are able to shape and control the magical energy to produce the desired effect.

Disturb Magic

 * The Disturb Magic is a unique magic that has the effect of canceling an opponent's magic by disrupting it and causing it to never materialize and scatter. Disturb Magic acts as a direct impediment to the opponent's manipulation of magic. It interferes with the flow of magical energy, making it unstable and incapable of cast magic spells properly. This magic specifically has a limited range, needing to precisely choose which part of the opponent's body will be affected.

Thought Acceleration

 * The Thought Acceleration is a unique magic that greatly increases thought processing speed, allowing Rainhart to quickly calculate all kinds of observational data and make extremely accurate trajectory predictions during a fight. It also allows Rainhart to perceive everything in a faster time frame, allowing him to move, dodge and read his opponents' movements.

Memory Partition

 * The Memory Partition is a unique magic that allows Rainhart to split his thoughts to form multiple independent thought processes. While normal people can only have a single "room" in their brain and focus on one thought, partitioning can divide this one room into several. Rainhart uses it to calculate the opponent's movements in battle, think out multiple separate ideas at once, and calculate data he gathers.

Demon Spear

 * A Trident weapon made by Laplace as a gift to the Superd Tribe, bearing a high resemblance to the Superd spear excluding its jet-black color. This magical tool amplified its Rainhart's physical capabilities several times over, nullified the effects of most magic spells, and heightened his already sharp senses. This spear has a curse that slowly eroding its wielder's mind, but Rainhart is unaffected by it, as he are immune to the effects of all curses.

Holy Sword

 * The "Paul's Beloved Sword", inherited by Rainhart after his father's death. A double edge sword that has a triangular shaped cross guard with two triangle holes. According to other party members of Fangs of the Black Wolf, that sword is "the lost holy sword of Saint Millis", as it was crafted by inserting the blade of Paul's existing sword into the hilt of the holy sword mock-up found in an ancient Millis ruin.
