Dayu

Dayu is one of Master Xandred's two followers, a female figure with a shamisen.

Personality
Dayu seems to be a bit of a downer. She also seems to be a bit arrogant as attacking her ally for simply talking arrogant. When the latter replied: "Better watch what you say. If it wasn't for Master Xandred where would you be?" She then threw a kunai at him, and called say that he had no right to talk to her, and called the latter a big-fisted no-brained nitwit. It looked like the battle would continue if Master Xandred hadn't intervened.

She also seems to have feeling for Deker.

She is apparently smart enough to contemplate a plan to assist in flooding the earth, while at the same time making something of personal value.

It was said in a later episode that she made a deal with Master Xandred to save her true love, in this case, Deker, but he tricked them and turned them both into Nighloks and wiped his memory, although there was no proof this story was about her and Deker, but it's very possibe.

Trivia

 * On the Nickelodeon page for Power Rangers: Samurai, it says that Dayu is half-human and once a full human. This is true for Dayu's Sentai counterpart, but it is still far too early to classify this Dayu.
 * In episode 6 it the above comment is hinted as Dayu makes a wedding dress, Octoroo comments that she is hanging onto the past, indacating that she was a human who was going to get married/was married. It is too early to tell if this is true and until than this is just speculation.
 * In Episode 15 a legend simular to Dayu's sentai counterpart is revealed that seems to match. Wheather or not it is true has yet to be determined.
 * Dayu resembles Camille from Power Rangers: Jungle Fury. In the same body structure, having an animal-like head, is a villain (though the latter turned good at the finale), and is in love with someone on their side.
