Name: Daiki, just Daiki (That's not her real name, but that's what we'll call her for a while)

Real name: Will be revealed in the story.

Power: Will also be revealed in the story (its much more powerful then the others) However for now she is a great swordsman, she could use any weapon (and I mean very good the best really) Without a weapon she focuses on pressure points. She is also acrobatic, fast, and has a extremely fast reaction time.

Appearance as a boy: A black haired boy with slightly lighter black tints and highlights. He wears whatever is comfortable, even girls clothes. He has deep beautiful green eyes, however sometimes his eyes will glow (at serous moments) And change colors sometime, but only at extreme moments. No one actually knows his eye colors because he always wears a mask (that means no one knows what his face looks like too)

Appearance as a girl: Much (and I mean much) longer hair, all the way to her knees, but she arranges it to her thighs, she also has more feminine features. In short she is beautiful (one of the most beautiful but no one actually knows that) while her male self is much more handsome. Her eyes are much more outstanding when she is a girl.

Personality: Rarely smiles, almost no emotion like a robot(but robots weren't around in that era) Usually has an emotionless face and her smiles are beautiful. (She sort of acts like Ai Mikaze from Uta no prince sama) However Daiki is usually more warm to Yona then to others (ok let me rephrase that, she is only warm to Yona) and he has a wicked sense of humour

Profile: Claims to be only 1 year older then Yona but is actually the same age as her. To everyone in the castle, he's just a mere servant to Yona (right-hand servant) A mere mysterious servant. He also helps Soo-won occasionally in his visits to the castle. Daiki is from the Lily village, where the Black dragons line comes from. They are very nice and wise, but Daiki is the only Black dragon born so far since the original black dragon. The lily village is unknown, it is claimed only to be a legend. They travel a lot so they probably won't be mentioned much in this story.

Love interests or crushes: She doesn't have one, nor wants one at the moment, all her thoughts are focused on assisting Yona.

Things you should know: Daiki left the village when he was 6 (not because he had a problem or anything, he just wanted to be free, and of course the lily village had no problem with it, they knew he could handle it) He started serving at the castle only 3 months after she left. King II saw something in Daiki and asked him to be Yona's main servant, that means he was usually around when Yona played with Hak and Soo-won, Yona was sort of spoiled when she was a princess so she didn't really bother to associate with Daiki since he didn't really talk to her that much. When Daiki is serving Soo-won (occasionally when he visits the castle) Daiki just does what he is told, so Soo-won thought that he was just a normal servant, but he was friendly with Daiki like with everyone else. Of course he noticed that Daiki was slightly more special then the other servants so Soo-won acknowledges him.
