An unidentified supernatural entity. Known as "Kuru" (The Coming). It is unknown who named it or if it named itself. Despite being called by a simple word meaning "to come," most who learn of its existence feel a sense of foreboding from the name itself. Regarded as the "Most Terrifying and Calamitous Entity." Wherever Kuru appears, a succession of disasters—accidents, catastrophes, illnesses, disappearances, malfunctions, conflicts, and injuries—occurs. Small bouts of bad luck chain together into major tragedies, or irreversible events happen without any warning. However, Kuru is rarely seen actually doing anything. It just walks. It just stands. It just watches. That alone is enough for the surroundings to begin warping. Objects fall. Roads are blocked. Machines break. Conversations between people fail to connect. Misfortunes pile up to an impossible degree, and even when trying to flee, one encounters yet another disaster. Whether Kuru causes the disasters or the disasters appear alongside Kuru is entirely unknown. Its appearance has no fixed characteristics. Witness accounts of its hairstyle, clothing, facial features, and height vary slightly. Yet, everyone is certain they saw the same entity. Even in photos or videos, the details can change every time it is captured. Even more inexplicable is the distance. Even after putting distance between them, it is suddenly nearby again. Even if one runs away, the next time they look back, it is closer than before. It was supposed to be outside the building, but the moment one looks away, it is standing at the end of the hallway. It appears to be pursuing. However, Kuru never rushes. In combat, it follows the same pattern; rather than flashy attacks, it triggers a chain of misfortunes around the opponent. The ground collapses, weapons break, attacks miss, and escape routes are sealed. The more one fights, the more their own actions invite disaster. After Kuru leaves, for some reason, there is no sense of relief that it is "over." Because Kuru didn't just "come"—it might still be in the middle of "coming." Possesses overwhelming power, ranking at the very top of supernatural entities. Rather than direct attacks, it excels at a fighting style that breaks down the battlefield by chaining disasters like accidents, malfunctions, and catastrophes. Even attempts to flee or counterattack easily lead to new disasters, making long battles increasingly disadvantageous. Its tracking and survival capabilities are extremely high; even if one thinks they've defeated it, it reappears, making it difficult to shake off completely.

An unidentified supernatural entity. Known as "Warau" (The Laughing). The origin of the name is simple: it is always laughing when witnessed. However, no one knows what that laughter signifies. Regarded as the "Most Evil and Insane Entity." Warau laughs regardless of the situation. Not just when happy. It laughs when sad, when angry, when frightened, and when someone else is being hurt. Sometimes it laughs loudly, other times it merely twists its mouth. There are even testimonies of hearing laughter inside one's head when no sound is being made. When Warau appears, strange changes occur in the emotions and perceptions of those nearby. A terrified person suddenly starts laughing. An angry person finds themselves unable to stay angry. Faced with a tragic event, laughter wells up. Conversely, those who were laughing lose track of why they were laughing and end up laughing even more. Whether the laughter itself is infectious, whether it warps emotions, or whether the minds of those who see it simply break on their own is unknown. Its appearance is also inconsistent. Sometimes it looks like a cute girl, other times only the face leaves a hauntingly strong impression. Details vary by witness, but the smile is the one constant. And that smile is the most terrifying part. While the mouth is smiling, the eyes are not smiling at all. It looks like it's having fun, but that doesn't necessarily mean there is joy. In combat, Warau doesn't stop at just defeating the opponent. It laughs if the opponent is afraid, laughs if they are angry, laughs if they flee, and laughs if they attack. The more the opponent reacts, the louder Warau's laughter becomes, dragging the surrounding emotions down with it. It is particularly abnormal when encountering "Kuru." The more the situation worsens due to disasters, the more Warau laughs. The more the laughter echoes, the more people's judgment fails, worsening the situation further. Kuru, who walks accompanied by disaster, and Warau, who laughs no matter what happens. When these two collide, it is not easy for those nearby to even escape. And no matter how terrifying the situation becomes, Warau remains unchanged. Always laughing. Without anyone ever knowing what is so funny. Possesses top-tier power among supernatural entities. Beyond physical abilities, it excels at warping the opponent's emotions—fear, anger, sadness—and perceptions, robbing them of sound judgment. It does not flinch when attacked and continues to laugh even when cornered, making psychological pressure almost useless. As combat drags on, the influence of the laughter spreads, turning the entire surroundings into a battlefield.
