Monsters in Relation:
Myo Galuna is a monster that has only been mentioned as a legend in the MH Orage manga. According to the legend, it "appears in the night sky, as bright as the stars."  It is also mentioned to be the "forbidden dragon of light." Although associated with images of paradise, many say it is actually as ferocious as a demon. An elite group of hunters, referred to as "Seal Hunters", constantly search for this monster.
