- "I was never truly a Nighlok. My heart remained human."
- ―Dayu's final words before her death.[src]
Dayu (formerly known as Dahlia) was a human/Nighlok hybrid and one of Master Xandred's two followers, working to bring the Netherworld onto Earth by flooding the Sanzu River.
History[]
Dayu and Deker were married
Prior to her service to Master Xandred, Dayu was once a woman named Dahlia, recently married to the man known as Deker. On the night of their wedding, the two presented each other with gifts: a katana for Deker and a decorated guitar for Dahlia. Sometime, in the night a fire broke out in their home while Dahlia and presumably Deker were asleep. When Dahlia woke to find their bedroom burning, Deker was nowhere to be found. The couple managed to escape the house, but Deker was severely injured.
Dayu becoming a Nighlok
In a moment of desperation, she called out for help and the "King of the Nighloks" (later revealed to be Serrator) appeared before her. Serrator agreed to save Deker, but at the cost of Dahlia's humanity. She agreed to his terms and was tricked soon thereafter. Serrator then cursed them both, which deprived Deker of his memory. Upon Deker's revival and immediate transformation into a Nighlok, he vanished, leaving Dahlia behind. Dahlia was then transformed into her current Nighlok form and became known as Dayu. 
TV STORY-Broken Dreams
Some unknown amount of time later, Dayu was approached by Master Xandred, who was drawn to the sad music Dayu played on her transformed harmonium, as it soothed his uncontrollable rage and painful headaches. He offered her a place as his minion, which she accepted. TV STORY-The Master Returns

As a half-Nighlok, Dayu served as one of the two generals working at Xandred's side to fight against the Samurai Rangers, yet she is embittered by her time in the Netherworld. Dayu still clings to the memory of her mortal life and her relationship with Deker, despite that he has no memory of their life together. She primarily regrets "cursing" him as a Nighlok with the unquenchable desire for the "ultimate duel". TV STORY-Boxed In (Samurai) On one occasion, she attempted to use the tears of newlywed brides to flood the Sanzu River and recreate her wedding dress, only to be foiled by the Samurai Rangers (Mia and Emily in particular).
She is skilled in battle, lasting long enough against the Rangers until Jayden prepared to attack her with the Fire Smasher. It was there that she was rescued and forced to retreat by Deker, who intervened in the battle upon finding the opponent Uramasa (his katana) was seeking. TV STORY-There Go the Brides She thanks him for saving her life and inquires why he wishes to fight the Red Ranger, to which he answers he is "cursed to satisfy this urge" for the ultimate duel and nothing else was important, not even his past life. TV STORY-The Blue and the Gold

When visiting the Tengen Gate, Mia and Kevin were told of the old folktale about a woman who made a deal with the King of the Nighloks to save her beloved and was tricked, foreshadowing the fate of Dayu and Deker. TV STORY-The Tengen Gate When Xandred damaged her Harmonium, Dayu fled the ship, intending not to return. She attacked a guitarist performing for the public, intending to use him to repair her weapon. This incites a battle between her and Mia, who happened to be passing by when she attacked. Xandred sends Rhinosnorus after Dayu. The monster blasts them with a sleeping spell and the two are sent into the dream world where Dayu's past life is revealed to the Pink Samurai Ranger. TV STORY-Broken Dreams
Dayu later finds the Furry Wart that was cast out by Master Xandred, which left her with someone to talk to at last. Dayu tells the Furry Wart that Master Xandred had broken her harmonium and wants revenge for it. TV STORY-Trading Places
Deker, Serrator and Dayu
Dayu thought Deker was dead. She went to the spot, where she thought he had perished, only to find his broken sword. There, she encountered Serrator once again. She was still mad at Serrator, after what he did to her and Deker in the past. Serrator offered to fix her Harmonium, and locate Deker, if she agreed to serve him, which she did. She later finds Deker in the woods. Deker revealed to her that his Ultimate Duel didn't free him from his curse, due to his sword being broken. Dayu convinced him to join Serrator, in exchange for fixing his sword, which he did. When they joined forces with Serrator, he gave them temporary replacement weapons: a dagger for Dayu and a Mooger's sword for Deker.
Later, Dayu returned to Master Xandred's side, after he fixes her Harmonium. Before this happened, she was betrayed and attacked by Serrator, who revealed that she was merely a pawn in his own master plan.
Some time after Serrator betrayed her, Dayu tried to convince Deker to join with her and Master Xandred, having completely lost all trust in Serrator. Her fears are further convinced, when she saw Serrator give Deker back his sword, while she silently hoped that Deker won't allow Serrator to use him as a pawn. When Serrator was locating the weakest point between Earth and the Netherworld, Dayu followed him there. When Deker arrived to claim Uramasa, Dayu watched as Deker betrayed Serrator, in a mix of relief and concern. Later, after Serrator's destruction, Dayu went to Deker's side, offering to help him find a way to break his curse. After he denied her assistance, she returned to Octoroo on the Netherworld ship.
Dayu (in her human form) tries to stop Deker from dueling Jayden
Later when, Deker and Jayden were fighting each other, Dayu sensed that the two are fighting each other in an epic duel. During nighttime, Dayu tried to stop Deker from continuing the duel because she doesn't want to lose him again. Since Deker refused and stated that he wants to be freed from his curse, Dayu reluctantly let Deker continue the duel.
Dayu's death
When Deker died, Dayu planned to spread misery in the human world and cast aside all humanity that was left within her. She fought with Mia, who broke her harmonium, inadvertently causing Master Xandred to return. After Xandred returned, he thanked Dayu for reviving him, but she stated that she played the harmonium for Deker. She further explained that she wasn't really a Nighlok due to her heart remaining human. Reminded of that, Xandred absorbed Dayu to gain immunity from drying out and the Sealing Symbol, leaving only a kimono, which he later threw in the Sanzu River in her memory. If Dayu was still alive in some form following her absorption, then she too was killed when the Samurai Rangers defeated Xandred, possibly allowing her to be reunited with Deker in the afterlife.
Personality[]
Most of Dayu's traits before becoming a Nighlok is unclear but she was shown to be a much happier woman especially when she married Deker. She was shown to be extremely noble as she willingly gave up her humanity for a chance at saving her husband's life only to be deceived by Serrator as he instead erased Deker's memories and turned him into a half human and half Nighlok. This event left Dayu angry and depressed with only her harmonium as a symbol of her happiness.
Self-confident, callous, and arrogant, Dayu kept mostly to herself, interacting with Octoroo and Xandred only when spoken to or during other needed times. She was also quite antagonistic to others, often insulting any Nighlok that show up on the ship. Xandred and Deker are the only ones she shows any respect for. However, underneath all her arrogance and scorn is actually a sad and tormented woman who lost everything she loved, and would do anything to get some semblance of that life back. She holds a desperate attachment to her harmonium, as it is the only reminder of the happiness she once had. Her time as a Nighlok has also made her quite bitter, attacking Mia even after she showed her compassion for her plight. She also holds a great deal of guilt over Deker, feeling responsible for his cursed half-Nighlok existence, and wants him to be free of it.
It is also evident that Dayu has a somewhat sympathetic and friendly side as she seemed to have cared for the Furry Warts (to an extent) despite seeming to be annoyed by them in some episodes. This side is visibly shown in "Trading Places" where after Xandred exiles one Furry Wart for 'mentioning her name' and Dayu seems to demonstrate this sympathy by picking it up and calling it a "poor little thing". The Furry Wart also implies that Dayu was close to it and the other members of its kind by saying that it has missed her although it is unclear if Dayu felt the same. But she constantly refers to the Furry Wart as her friend in some episodes, proving she does seem to genuinely care for it as she can often be seen stroking it on occasions. Dayu also displays a forgiving side as she returned to the Netherworld and pledged her loyalty back to Xandred after he repaired her beloved harmonium.

Arsenal[]
- Harmonium: Dayu's guitar, the "Harmonium" (transfigured into a shamisen) serves as her primary weapon.
- Blade Deployment: Dayu can remove the head of the weapon to remove a shirt stabbing sword to use in combat.
- Blade Rush: Dayu's strongest attack where she would remove the blade in her Harmonium and then rush at her enemies, striking them multiple times before skidding to a stop and researching her weapon. The enemies would then burst and collapse. This could take out five Samurai Rangers since she never used this around Antonio.
- Energy Empowerment: Dayu can charge up her blade with light purple energy and slash at full force.
- Flame Empowerment: Dayu can also charge up her blade with purple flame and slash at full force.
- Soothing Music: According to Master Xandred, the "Harmonium" soothes him, as its music is a song of despair. Only Dayu's song, while performed and played using this instrument, can soothe Master Xandred and his chronic headaches.
- Blade Deployment: Dayu can remove the head of the weapon to remove a shirt stabbing sword to use in combat.
- Dagger: After agreeing to help Serrator with his schemes, he gave her a special dagger-like weapon to use while he took her damaged instrument. This was discarded once she got back her Harmonium.

Family[]
- Deker: Deker and Dayu got married and on the night of the wedding, they went back to their home. Deker and Dayu gave each other gifts. Their home got on fire and Deker's life was fading fast. Dayu called out for someone to help him. Serrator then appeared and offered to save Deker, if Dayu could trade her human life to be a Nighlok, which accepts. Deker was revived but Deker's memory of him and her was wiped away. However, Deker might've reunited with Dayu in the afterlife (since his curse was broken before his death).
Others[]
- Serrator: Serrator cursed Dayu and Deker to be human/Nighlok hybrids over 200 years, the curse leaving Deker with no memory of Dayu ever again.
- Master Xandred: Even after being loyal to him, Master Xandred burnt Dayu's harmonium. However, he later absorbed Dayu's human half before battling the Samurai Rangers.

Notes[]
- Dayu is one of the many villains, male or female, who were once a human before becoming a monster.
- Dayu shares the same name as her Sentai Counterpart.
- A harmonium is not a stringed instrument, but a free-standing keyboard instrument, similar to that of an organ.
- This could be a goof on Dayu's (or a writer's) part, or perhaps it is just her nickname for her shamisen.
