Mystery of the Wind Witch is the 146th chapter of the InuYashamanga.
Synopsis[]
The poison from the shard in Kōga's arm is spreading. Inuyasha says the only way to save Kōga's life is to cut the arm off.
Kagome doesn't want Kōga to lose his arm, so she purifies the poison by striking the shard with her sacred arrow. Kōga wakes up and vows to get vengeance for his fallen comrades.
Kagura confronts Naraku about Inuyasha's Wind Scar. It is revealed that Kagura is a creation made from Naraku's flesh. Naraku squeezes her heart and tells her it would be easy for her to return to the body from which she was born.
Kagura's elder sister (and Naraku's first incarnation), Kanna, is introduced.
