A monster created when will dwells within lava tinged with mamono mana. They have a violent and ferocious temperament. They give in to their bubbling, vehement passion and aggressively assault human men, swallowing them with their lava-like body and keeping them. Their body is born from lava, and its properties and heat vary depending on color. The black, cool, and hardened-looking parts are comparatively hard and low temperature. In contrast, the red hot parts are softer and hotter than human skin. This lava that boils seeking a man doesn’t inflict burn wounds on humans, but as for those who touch it, the part it touches takes on heat and starts to feel hot. Furthermore, they’re weak against water. When a considerably large amount of water is poured on them, their normal ferocity temporarily fades, and they even show a clingy attitude towards men. Also, if it’s a volcano, sometimes they even inhabit snowy mountains. Their ferocity dims because the chilly place is hard on them, but to a man who’s freezing on a snowy mountain, their hot, soft body is warming to the body and soul, and it’ll be even more attractive than usual. The power of lava to cover a chilled body in warmth and pleasure is so vast that it’s enough to make a man experience a sensory illusion like his body has melted instantly. They have no tails or horns. They have slime-like bodies with some parts of their bodies being solid like obsidian.
