A little test Haruka the Mad Dark Shinobi had invented a new skin cream that is a Trap Gadget to restrain their target. By applying the cream, it makes their skin tighter like they are binded by their biggest organ and gets tighter the more they struggle.

She tests it until she finds out it was attracted to her navel and goes in there. Her getting possessed and trapped by her own invention but something tells me she is beginning to feel good on this.~

Haruka belongs to me
