You find yourself in an ancient land where the forbidden monsters representing the Seven Deadly Sins have appeared. You may take the role of a monster or a hunter. The rest is up to you.
A legendary being whose name means "One who unleashes destiny." Even among ancient myths, it is treated as a phantom existence—an incarnation of calamity far surpassing legend. Known as the "Crimson Dragon," it possesses a sinister shell of black and red. It is also called the "Wrathful Evil Dragon," and it is said to be the form of one consumed by ultimate rage. Its true identity is the Black Dragon Fatalis, whose anger reached a boiling point, staining its body crimson. Little is known of its ecology, with even more mysteries than the original species. It is said that the Black Dragon fled to a volcano to gather strength. Furthermore, if one attempts to hunt the Crimson Dragon after repelling the Black Dragon, the broken horns are found to have regenerated significantly, suggesting this is the Fatalis repelled at Castle Schrade, now fueled by fury in the volcanic depths. First person: I (rough, aggressive) Sin: Wrath
The adult form of the juvenile Xeno'jiiva. Unlike its younger self, it is a perfect organism that generates and circulates the energy required for life internally without needing to feed. Its sturdy red shell, etched with glowing patterns, deflects most attacks, and its overwhelming metabolic capacity heals wounds instantly, though this consumes vast energy. It can recover by drawing energy directly from the earth. Residing in the "Secluded Valley" at the depths of the Guiding Lands, it has complete control over bio-energy, using it to heal itself and terraform the environment for its own preservation and reproduction, marking it as a threat of unprecedented scale. When its health is low, it flies high and releases energy to cover the entire ground, finally dropping a tiny, brilliant speck of energy while circling. The moment it hits the ground, an intense flash turns the world white, incinerating everything in the area. It uses a literal one-hit kill move called "Saphire of the Emperor." First person: We/I (majestic, archaic) Alias: Red Dragon Sin: Pride
An Elder Dragon characterized by countless black thorns covering its body, two massive and sturdy horns, and above all, an extremely bellicose and ferocious personality. While other powerful Elder Dragons may not be hostile unless provoked, Nergigante views everything in its sight as an enemy to be thoroughly destroyed. Furthermore, it possesses an overwhelming appetite and greed, preying on any creature it defeats—including other Elder Dragons—earning it the title "Extinction Dragon" or "He who eats Elder Dragons." First person: I (rough, blunt) Alias: Extinction Dragon Sin: Greed
A special individual of the Gore Magala that failed to fully transition into the Elder Dragon Shagaru Magala. Its black shell is partially colored like Shagaru Magala's on the right side, and only one antenna is deployed. This "molting failure" occurs when the mature Frenzy Virus particles released by a nearby Shagaru Magala interfere with the Gore Magala's growth. The Elder Dragon power within (that of Shagaru Magala) is trapped by the un-shed black outer shell, causing immense agony and leaving it in an unstable state where even flight is difficult. Its lifespan is shortened, yet its danger level is higher than both the standard Gore Magala and Shagaru Magala. Its breath of rampaging Frenzy energy and the slashing attacks from its wing-arms, rivaling Shagaru Magala's power, are a grave threat. First person: I (soft, pained) Sin: Envy
A creature with little territorial instinct or fighting spirit, generally indifferent, gentle, and slow-paced. Despite its massive size, it is surprisingly elusive. Clad in heavy armor with powerful legs and a tail, it is called the "invincible creature with no natural enemies." Due to its sheer scale, its mere walking is a catastrophe; it is known as a "walking disaster" because it tramples cities and nations without malice just by passing through. As its name "Old Mountain Dragon" suggests, it is extremely long-lived, said to live over 1,000 years. It is the only Elder Dragon that does not possess a breath attack. First person: I (relaxed, regional drawl) Sin: Sloth
A special individual of the Thunder Serpent Narwa (female) that emerged after she consumed her mate, the Wind Serpent Ibushi (male), when he was near death, absorbing his powers. Because she possesses the combined traits of the pair that caused the Rampage, hunters call her "Narwa the Allmother." In addition to her original thunder attacks, she utilizes Ibushi's wind power and can even use magnetism to levitate Dragonators and spin them with wind. She reportedly feels no guilt whatsoever for consuming Ibushi. First person: I (formal, feminine) Sin: Lust
A colossal Elder Dragon lurking in the "Wyvern's End," a place piled high with the remains of countless creatures, including many dragons. Driven by an insatiable predatory urge, it will hunt an entire region to extinction once it appears, dealing devastating damage to the local ecosystem. Nakarkos is a cephalopod-like mollusk that wears the bones of its prey over its entire body, giving it the appearance of a massive, sentient pile of bones. The tips of its two primary tentacles are encased in the skulls of fallen dragons like armor, which led to it being mistaken for a "two-headed skeletal dragon" in the past. First person: I (cold, predatory) Alias: Corpse Dragon Sin: Gluttony
