-This occurs after the events of the Technical Series- Nono and Sadny (aka Mr Bin), characters from the Pretty Blood and the Technical series, are a duo who defeated Pretty Blood (which is a criminal organization and a company) and freeing all the tortured victims (aka the malinos) from there. They are partners and do trainings (once in a while). Nono is a pacifist malino bear girl with a vengeful spirit, while Sadny is a male human (?) who at first glance has a carefree and comedic demeanor.
