[pokori]

I don't think it looks "mi" to a Japanese person...at least not to me. I tried so hard, but I just can't see mi from this picture... The first thing came to my mind was ゐ, like Sumippi san said, but then again it seems a bit weird at the ending stroke, so I hesitated to respond...
I also thought that it might be 丙's sousho?(草書or gyousho?) or something but that doesn't seem right either...
