Frilled Dragons are smaller than most other breeds, but when threatened, they stretch out their wings and frills to appear larger. They generally do not like to fight and prefer hiding to confrontation. Frilled dragons live in small groups and often band together to scare off potential threats. Males also use their frills as a way to attract mates, with those displaying the “best” frills being more likely to breed.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Meruto is one of the most gentle dragon in the group although she usually prefer to spend her time alone. She love to spend most of her days outside of the cave, feeling the breeze and pretty much relaxing on top of a large boulder nearby. Due to her special ability which is when her large frills are opened, it allow her to detect even the slightest of sound in the air and allow her to pinpoint the exact location of the enemy, she has taken the role as the group's "radar". Together with Haru, its not rare for the group to know where and when the enemy will attack in advance. She also naturally able to produce extremely corrosive acidic poison which can melt practically anything when spit out.
