Thunder Dragons are the masters of electricity. Their wings gather energy as they soar through the clouds, and when they clap their wings together they can create devastating arcs of lightning. They can stay airborne nearly indefinitely, landing only to sleep and breed; they catch their prey from the air and take moisture from the clouds. A thunder dragon’s roar is considered to be an omen of misfortune.

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.

Hime is the "Princess" in the group, always acting with strong facade in front of the others. Underneath, she is actually quite a nice dragon, a bit shy even, especially when face to face with Raikou who she is secretly nursing a crush over which ironically, everyone else in the group knows about except Raikou himself. During battle, she is literally the "jack of all trade" as she can attack by summoning thunder bolts from the sky to destroy her enemies from above for middle range battle or coating her wings with thunder, turning it into razor-sharp blade for close quarter combat.
