Deca

A member of Polyhedron assigned to the Equinox-Solstice case as a security guard for EquSol.

She was old friends with Penta, and helped him escape the company, leaving him with a scarf to remember her by. 

She hasn't seen or contacted him since for his safety, but she misses him. Unbeknownst to her, her movements are being tracked by Polyhedron to see if they can find him for fear of whistleblowing.

Her power is making creatures out of smoke that she can link her senses to, most often her cat. Officially it's called Deca-001 by Polyhedron, but Deca calls her Kiki.
