This is the Blue Key, Aeayuri, from my CS comic, 4Key. Her element is Water, and she is the Liquid Emblem of the 4.
Aeayuri: Aeayuri is a lithe, non-caring, intelligent dragon, drawn to these extents after years of "Avoiding" (She doesn't like to use the term "Running from") her enemy, the Black Key. She's spent her years alone, after her parents were killed in the Black Keys' search for the 4 Keys. She has a straight-forward personality, seemingly without fear, in most cases, though on the inside, she's ravaged from her hard, fear-filled lifestyle and waking up every morning fearing she'd been captured in her sleep or always getting the sense she's being watched by the Black Keys' agents. As she is a Key, the Black Key are aiming to capture her for power. She's not "quiet", in fact she's rather social, but she's certainly not the "happy" kind. Though it's really hard to explain her personality, she barely even has any--most of the time, she's a blank, joyless Dragon, but she will do what she can to save the innocent, even if it costs her own life. She doesn't care if her words hurt others, as long as she's speaking the truth, and though she may not seem like it at times, she's the most trustworthy Key to have lived. She's like the strong-but-not-silent type, who will tell you whatever she thinks you need to know even if it will destroy your feelings. So, she's basically also the one to be trusted to tell someone a harsh truth.
