Sunny's Process to Natural Supremacy

Sunny's process of Supremacy is depicted as a profound and paradoxical act: He must die, but only by his own hand. This is not just a symbolic gesture—there is a crucial metaphysical reason. If someone else were to kill him, his shadow would be sent to the Shadow Realm and be consumed, erasing him from existence. However, because the shadows of those Sunny kills are instead drawn into his own Soul Sea, by ending his own life, he sends his shadow there instead. This deliberate self-inflicted death allows him to avoid the finality of true death and sets the stage for transformation.^[1]

Upon killing himself with Serpent—the blade that embodies Death—Sunny's body is destroyed, but his shadow remains. It is through this act that he breaks the invisible wall preventing him from reaching Supremacy. In the silence of his Soul Sea, within a black marble temple surrounded by a dark lake and seven lightless suns, his shadow reforms and becomes aware. As he opens his tenebrous eyes, a ripple of power spreads across the realm, and the still lake, suns, and shadows respond to his rebirth. This marks the emergence of his nascent Domain—something he had been building unknowingly through the countless battles and deaths he caused.^[1]

The shadows, now forming a vast legion, kneel before him in submission. These entities, once lifeless, come alive at his presence, recognizing him as their Sovereign. This Domain, composed of all the shadows tied to him, is the manifestation of his supremacy. Sunny, having defied death without the aid of any artifact or divine blessing—relying solely on his indomitable Will—returns not just alive, but transformed. In doing so, he achieves Supremacy: not merely survival beyond death, but command over a Domain of shadows, a monarch reborn through willpower and sacrifice.^[1]

Sunny defied death by willingly ending his own life, sending his shadow into his Soul Sea rather than the Shadow Realm, allowing him to resurrect through sheer will and, in doing so, ascend to Supremacy and manifest a powerful Domain of shadows he had unknowingly built all along.^[1]

Sunny needs to die to achieve Supremacy but cannot let anyone else kill him. He chooses to end his own life by piercing his chest with Serpent, a blade embodying Death itself.^[1]

The significance of his self-death is that it allows his shadow to enter his Soul Sea instead of the Shadow Realm, avoiding complete annihilation. This is crucial because shadows of creatures he kills do not go to the Shadow Realm but to his own Soul Sea.^[1]

By killing himself, Sunny ensures that his shadow is sent to his Soul Sea, bypassing the Shadow Realm. This act shatters the barrier that was preventing him from attaining Supremacy. This is the turning point in his journey, marking the moment when he transcends death and achieves a higher state of power.^[1]

Upon coming back to life, Sunny's nascent Domain manifests. This Domain is composed of the legion of shadows he had unknowingly been building throughout his journey. These shadows, now under his control, are his Domain, and they are symbolic of his newfound power and authority.^[1]

With his Domain, Sunny assumes a godlike position, with the shadows prostrating themselves before him as their Sovereign. His will, which allowed him to break the absolute law of death, has galvanized his soul into becoming Supreme.^[1]

Sunny has ascended to the Supreme Rank, which brought several profound changes:^[2]

• His physique evolved from Transcendent to Supreme, granting him immense physical power.^[2]
• His Will became a far more tangible force, allowing him to bend the world to his will and use it as a weapon.^[2]
• The nature of his soul changed: it could now be freely unleashed upon the world via the medium of a Domain, thus subjugating it.^[2]

Sunny's soul essence is nearly limitless:^[2]

• He possesses seven cores and Soul Weave, enabling a high rate of essence regeneration.^[2]
• He draws constant essence from his Domain, which is composed of tens of thousands of silent shadows collected by slaying beings.^[2]
• This connection to silent shadows has deepened and evolved, supplying him with an inexhaustible flow of spirit essence.^[2]

Unlike most Supremes who draw power from external Citadels and the faith of followers, Sunny is unique because:^[2]

• He carries his Domain within his soul, making it self-contained.^[2]
• His Domain is always with him, unlike other Supremes who must remain within their established Domains for full power.^[2]

Upon reaching Supremacy, each of his shadows has grown immeasurably deep and powerful, resembling the infinite expanse of an ocean. From within his soul, Sunny can open a metaphysical gate—described as leading to the "tranquil depths of his lightless soul"—through which his shadow army emerges into the real world. This army consists of the shadows of countless Nightmare Creatures and powerful individuals he has defeated across various realms and timelines. Once unleashed, they manifest physically, flowing across the battlefield in eerie silence. These shadows are not static; Sunny's Domain is self-sustaining and recursive—each enemy slain by his shadows adds a new shadow to the dark lake within his soul, which then joins the fight, effectively creating a growing, regenerative force. At the head of this legion Shadow Saint, serving as his general.^[3]

His Domain functions not only as a reservoir of essence but also as a living battlefield that merges the spiritual and physical realms, making him a Sovereign whose authority mirrors the inevitability and finality of death itself.^[3]

• Sunny's human body was destroyed by the radiant white sky of Godgrave after he stabbed himself with Soul Serpent in Chapter 2246. The only thing remained was his disembodied shadow.^[2]
