She looked at Nyx as she acted cute and kinda sighed to herself. She didn't understand why someone with her appearance would act like that. If it was an act, she would surely figure it out soon since she was good for that.

Momo looked over to Airi and Dim who (should be) was looking at collars now (Sorry for the slight control, I'm just trying to make it easier for you to reply) and then looked at Nyx, who had walked over to her with a black collar. "You act shy, but pick something that shows true darkness." she smirked a bit. She took the collar and wrapped it around her neck. "Tell me when it's just tight enough to let you move and breathe freely, but don't let it be too lose either, I can adjust it later if you have problems." she started to tighten the metal piece in the back, letting it tighten until it was as tight as Nyx wanted. After she finished tightening it, she took out a small keychain looking board with a bunch of different buttons. "I will be putting you down as number 2, sorry to label you with a number, but names are too large to write it. Just always remember, button number 2." she smiled as she pressed the button and a little red light in the back, next to the clutch, started to flash every 10 seconds.
