Reinhard van Astrea

Reinhard van Astrea is the most powerful being in the world serving as the current Sword Saint of Lugnica and the knight to Felt, born into the legendary House van Astrea as the son of Heidrich and Louanna and the grandson of Wilhelm and Theresia. His life is defined by a tragic heritage, as he inherited the Divine Protection of the Sword Saint at age five during a battle, leading to his grandmother’s death and a permanent rift with his grandfather, Wilhelm, which fostered in Reinhard a personality of extreme politeness and humility masking a deep sense of self-loathing and the belief that he is a weapon rather than a human. Despite his status as a "walking plot device" who cannot cast magic but instead absorbs all environmental mana to bolster his superhuman physical prowess, he maintains a close bond with Subaru Natsuki and seeks to fulfill his duty as the ultimate protector of the realm. His power is truly defined by his unprecedented access to over a hundred Divine Protections, a list that is infinitely expandable because the world grants him any protection he wishes for in the moment, including the Divine Protection of the Sword Saint for mastery of the Dragon Sword Reid, Mind Over Matter for god-like strength, Avoidance and Evasion to make him impossible to hit with projectiles or melee strikes, First and Proceeding Sight to predict and counter every enemy movement, and elemental resistances that reduce all magic damage by eighty percent. Furthermore, he possesses utility protections like Lake and Cloud for walking on water and air, Abyss for total darkness vision, and Master of Weapons to turn any object into a lethal tool, while his ultimate failsafe remains the Divine Protection of the Phoenix, which allows him to resurrect instantly and immediately wish for "Phoenix II" to ensure he can never truly stay dead, making him an invincible, self-generating force of nature whose existence ensures the world's survival at the cost of his own perceived humanity.
