Character: The Matthews Twins and their Bond-Ghosts

(Maddie Hasson as Nadia Matthews)

Fraternal twins, Nadia is blonde and slim like her mother while Nate has the curly dark hair and strong jaw of their father. The only thing they share is the solid shade of blue of their mother's eyes.  

Both are competitive and stubborn and likes to argue, especially with each other. 

(Jesse Eisenberg as Nate)

While Nadia has a volatile temper, quick to blow and equally quick for said temper to blow over, Nate simmers silently and can hold a grudge until the world stops turning. 

Both are competitive and stubborn and likes to argue, especially with each other. 

Like most Twins are, they have a strong mental bond with each other, so much so that if Nate was injured, Nadia not only feels the injury but also suffers the physical injury herself. 

Years older than their younger brother Seth, they act more like his younger siblings but when push comes to shove, the twins will do anything to save their baby brother. 

Reapers have a personal sigil, a magical circle that they apply when catching a ghost and tying them down to our dimension in order to seal them away, and this sigil usually manifests as a mirror of their inner personality. Nadia's sigil, much to the amusement of her two brothers, takes form in a circle made by thorns while Nate's is a circle made of blue fire. Interestingly, both their circles fit together completely, allowing them to work simultaneously with both sigils much to the dismay and envy of other Reapers. 

Bond-Ghosts

Bond-Ghost are the guardians of Reapers, as Reapers are vulnerable to possession and mental attacks, the Bond-Ghosts protects them from such dangers. Souls connected, they draw power and stability from each other. Having a Bond-Ghosts is a big deal for Reapers and is chosen carefully because the connection once made can only be severed by death. 

It is not strange if a Reaper risks possession rather than choose the wrong ghosts to bond with. 

(Max Irons as Vincent)

Vincent is an Englishman who lived in the Victorian era who holds not-so-Victorian values although he often chides Nadia for her foul mouth and unlady-like behavior just to needle her. He is very protective and secretly ruthless. Nate often commented that Vincent was either an assassin once upon a time or a politician. Vincent has a sly wit and a dry sense of humor that makes Nadia snicker and leaves everyone else confused. Indolent by nature, it takes a while to rile him up but when he's rile, it's hard for him to come down again. 

(Zoey Deutch as Lizzie)

Lizzie owned a salon in the wild wild west once upon a time, she hides a blade in her corset, a derringer under her bustled skirts and a knife in her boot. Bold, flirtatious, wild, Lizzie delights in scandalizing everybody with her ever-changing wardrobe that shows off her assets becomingly. And Nate only encourages her, amused by her wiliness and cunning. Both Lizzie and Nate are bad influences on each other but she is fierce in protecting her Reaper, launching everything in her considerable arsenal at the mere mention of danger in Nate's vicinity.
