Serafine is a normal Edenian where she does not have a ability like most Edeninans do pretty much like Sokka from Avatar the Last Airbender since he's not a bender but Serafine does know ninja moves that she learn from her father who was normal
Also like Lear she has beads that goes around her left eye like Lear that goes around her right eye and its a family think or heirloom which Serafine considers
Lear just thinks its a fashion thing at first than learns out its passed down from family to family though Limus wont get it
And one more thing
