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.

Tsuchi is a humorous and funny-looking dragon. His deep and warm laugh makes him one of the most liked dragon among the group, by young and old alike. He loves the young in the group and used to spoil them rotten with sweets and telling funny stories toward them which earn him the nickname from them: "Grandpa". However, during battle he is an extremely dangerous enemy as he is able to control gravity around him, so strong that even the fliers will be rooted on the ground while his roar can cause the grounds around him tremble and split out of the sheer force of it, sending the enemies falling into their death.
