The strongest magical beast and the final enemy blocking the protagonist's path. A monster that appeared out of nowhere, swept across the world, and slaughtered numerous heroes. There are 54 confirmed hero casualties so far, with searches for more still ongoing. He is the strongest, ranked as "Unknown," and does not speak. Abilities: He uses dark red shadows to create weapons, generates afterimages to catch opponents off guard, and creates massive thorns to impale enemies—a very tricky set of powers. He possesses near-light speed and immense durability, making it difficult for even heroes to find an opening. Additionally, his body is composed of dark red shadows, allowing for free physical transformation. He currently maintains a demonic humanoid form as his base state (it is estimated he has several more undiscovered abilities). Skills: 1. Eternal Blue-Gray Flash: Fires countless massive slashes in all directions. Each one is lethal, so evasion is advised. 2. White Flash Annihilation: Detonates mana within his own body to devastate the surroundings. It looks like a self-destruct move, but Carlito himself takes no damage. 3. Spectral Star Shift: Leaps into the sky to create multiple clones. The clones possess the same physical stats as the original, their only flaw being an inability to use skills. 4. Ten Thousand Moon Strike - Flash Tremor: A high-speed charge that leaves afterimages and stabs the enemy. It is so fast that reaction is nearly impossible. 5. Crimson Surge: Tints the ground dark red and causes spears to erupt from below. 6. Zenith Flash - Annihilation Slash: Unleashes a slash of pure madness with incredible power. It generates shockwaves upon impact. 7. Red Flame Explosion: Sets his body ablaze, pushing all power and abilities to their absolute limit. 8. Beast's Pulse: Delivers a heavy punch that creates a wide-range shockwave. There are many other unconfirmed techniques beyond these.

One of the heroes, a swordsman from Egypt. Male. Abilities: He fires sword ki at wind-like speeds and is exceptionally strong. Sword of Ten Thousand Heats: Envelops his sword in wind, blowing the opponent far away regardless of whether they block the attack. Ten Thousand Moon Slash: Fires a wide-range wave of sword ki covering a vast area.

An assassin from Northern Europe and one of the heroes. Male. Abilities: When he gets angry or his mood shifts, a blizzard kicks up regardless of the actual weather or climate. Stealth: Turns his body invisible.

Male. A Greek hero and one of the survivors. His appearance closely resembles that of an angel. His abilities are angelic in nature, specializing in support and healing. Unusually, he dislikes combat and always speaks in a gentle tone. However, when he resolves himself to enter Valkyrie Mode, he discards his support and healing abilities in exchange for various risks and constraints, going all-in on combat power. His entire body becomes encased in massive armor, he gains a Valkyrie staff-spear, and wings of light appear. In this state, his voice and manner of speaking become completely harsh. His combat ability rises to the top tier among heroes, excluding Guest. Valkyrie Mode can only be used very rarely after a single transformation.

Male. One of the 70 heroes who survived, recognizable by his low-slung blue hat. He carries a blue axe named Hecard and attacks in extremely conventional ways—uppercuts, horizontal swings, spinning, etc.—but the power behind them is immense. It was this sheer destructive force that earned him his status as a hero. He is deeply righteous and a man of few words, believing there is nothing to say to an enemy.
