With shaking hands Mia reaches out and takes the collars from the demon girl and hands one to Chloe the two girls wrap the collars around their necks just as they lock the clasps a pendant forms on the collars

The demon girls eyes light up she put her hands under the girls chin and tilts their heads up she smiles with excitement “ahh birth sisters..mother is definitely going to be happy” she turns around and looks at Kako and her familiar who is not trying to play with her prisoner

Walking back to the centre of the pentagram the demon girl takes a deep breath once again the pentagram glows red. The stones begin to float she hold out her hand and the stones move in front of her she says a chant the stones make a circle a portal opens

She looks at her familiar “take her I’ll bring the other two” her familiar stands up a leash forms in her hand she locks one end onto Kakos collar she pulls on it “up” Kako refuses to move suddenly her collar tightens around her neck making it hard for her breathe the familiar pulls on the leash again “up” Kako slowly get up her collar Loosens a little

Kako looks at Chloe and Mia scared to speak she just nods at them the demon girls familiar pulls on the leash again and points to the portal “go” for a second Kako hesitates her collar shocks her causing her to moan in pain the Familiar points in the portal again and says go

Kako walks forward and enters the portal the demon girls familiar follows her throw the portal the demon girl looks at Chloe and Mia “are you two going to behave?”
