Dayu

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.
