My Stuff: Have you seen this blue haired – Anime-Figure ? (Oni Musume)

I have absolutely no idea where this character is from, can you tell me?
Got this figure about 5 years ago as a gift and unfortunately got no information about the figures origin :(

Some details:

• Product: Figure
• Character: Oni Musume (Blue Demon Edition)
• Dimensions: 23cm (9″)
• Weight: 200g (0,4 pounds)
• Material: PVC
• Box: Unknown
• Edition size: Unknown

Personal stuff:

• Where I got this from: It was a gift
• What I like most: The anime look (it’s my only figure in this style)
• What could be better: The base should be a bit bigger, the figure is not very stable
• Personal Rating: 2/5

Have you seen this character or know from which anime or game this is, pls post in the comments!

I found out who she is due to my awesome Facebook-Connections =)
