Not much is known about David he is introduced along with his twin in Chapter 77. Apparently he loves to torment Tiki and makes it known that his mission was to kill Cross. Appearance-wise he also posesses the crosses on his forehead and the dark skin (though Tiki calls him Pale). He has black sleek hair and raccoon eyes. He seems very violent, obnoxious and always ready to fight. He waves a revolver around and uses it to unleash his attacks together with his brother Jasdero. (A.K.A Debit, Devit, Debitt, Devitt)

Not much is known about Jasdero. He is David's twin and his personality is much like David's except he doesn't seem to speak much at all and is perhaps a little wilder where David seems more calm. He was also in charge of killing Cross with his brother. Unlike David, he has long light colored hair and his mouth is sewn together. He seems to be good at manual labor as he pulled the cart that Tiki, Skin and David rode on, he's also speedy. He swings around a gun just like his brother and he annoys Tiki aswell. His powers are also linked to his revolver and functions along with his brother. (A.K.A. Jasdelo, Jasdel)

As a team they call themselves one entity named "Jasdavi". Their power as a Noah is evident when they are together as the "bullets" in their guns function together and change accordingly as a few attacks have been seen so far, Divine Punishment and a myriad of colored "bombs" Blue (freezes things), Red (Fire attack), White (Nullifies their own attack), Purple (disguise/confusion attack) etc... And it has been revealed that their powers go beyond that because they are based on their imaginations. whatever they can create in their minds at the same time, become real. No official spellings yet for them.

The twins represent the Bonds of Noah.
