Fan Casting Shadow Monster in Blood-C (Season 2)

Comes from Nono's shadow and has control over her. The shadow is shapeless, as such it can take any form it desires for offensive. It can turn its arm into a sickle-like apendage for hard strikes. It can also turn part of its body into spikes or as a large mouth and it can also extend tentacles to bind Saya and drag people into its body where a seemingly alternate dimension is present.
