Everyone is looking for Grimm

There's a peaceful city called Portland. Every day, murders, kidnappings, and other mysterious, strange occurrences occur in this city, and they can't explain it. There's a police force there, and Nick Bernhardt—male, a Grimm, but no one knows it except his friends—works there. Also working there are Hank Griffin—male, Nick's partner in homicide investigations, and he knows he's a Grimm; Drew Wu—male, a sergeant, also Nick's friend, and he knows he's a Grimm; and Sean Renard—male, a captain, who also knows Nick is a Grimm, but he's also a witch. Nick's friends are Monroe, a male wolf-like creature nicknamed Blutbad and a source of information about the supernatural; Rosalie Calvert, a female fox-like creature nicknamed Redtail and also Nick's friend; Juliette Silverton, a female veterinarian and also a witch-like creature nicknamed Witch; and Adalind Shade, a female witch-like creature nicknamed Witch and Nick's friend. There's also a second Grimm, Trebul, a female Grimm nicknamed "Trouble." She helps Nick, Hank, Wu, and Sean search for various creatures. Only Grimms can see these creatures, and humans can only see them if a Grimm looks at them. Murders have been frequenting the city, not of people, but of creatures. Nick, his friends, and the captain are trying to find out who's behind it, or what?! Two weeks passed and the phone at the station was ringing off the hook, suddenly Nick and Trebul felt something like a new Grimm, and that's true, a new Grimm with a very unusual appearance has appeared in the city, all that is known is that this Grimm is a girl, that she is wearing a black top, black pants shimmering with red, black and red sneakers and a red jacket, her right eye is black, and her left is blind, her hair is long black down to her knees with red ends, she has wolf ears and a tail, but only Grimms can see them, she is 20 years old, her name is Daria/Dasha Now: everyone is sitting in a cafe and wondering who this new Grimm is and what her name is.
