Green Dragons are also sometimes called “earth” dragons. They usually live deep within caves, and have power over the earth. They are capable of launching boulders at high speeds, and can cause earthquakes by slamming down onto the ground.

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.

Furuemasu Tsuchi, as a Green Dragon, was named after the Japanese words meaning "Trembling Earth." All she does is stay in her cave all day, pacing back and forth and sometimes launching boulders. The other dragons stay well away from her, except for her friend Ookii Maruishi, who always stays by her side. Whenever Furuemasu Tsuchi is sad or angry she stands up on two legs and slams her feet onto the ground. By doing this however, reminds her of the terrible mistake that occurred long ago. One of her earthquakes killed a innocent egg. Now that she is in depression, the last thing she would ever do would be to go outside and confront the others. Even with  Ookii Maruishi, she is alone.
