Well I know that Wild and Horned Hermit was discussed within the Cirno game thread here
http://www.shrinemaiden.org/forum/index.php?topic=6676.msg391338But to be fair, I feel Wild and Horned Hermit needs a separate thread so that it can be known. Because I didn't noticed it and almost did the same thing.
Anyways, in for everyone that doesn't know already it's another Touhou comic that ZUN wrote and got an artist too.
The new charater that has been introduced is Kasen Ibara, a hermit who's looking for the "arm of a kappa".
And Ibara "might" be linked to the oni of old ledgend named "Ibaraka Douji" who lost his arm and tricked someone into slicing off thier arm to so he could replace his. And from the look of Ibara's right arm it looks all wrapped in ribbon as if something is wrong with it. Thus why the connection.
And also the oni of legend has a connection with Douji Ibuki thus it's believed that Ibara could be...
But this is alll speculation right now since she was just introduced, but it's an interesting connection non the less.
