Master

Spider Demon is an old man who murdered Nazuna's father. He disguised himself as a human monk and raised Nazuna without her knowing that he was the murderer of her father. He was awaiting Inuyasha and his party, in Nazuna's House, so that he can snatch the Shikon Shards. After a big commotion about Inuyasha changing into a human, and then changing back, Inuyasha defeated Spider Demon. Also, after Inuyasha defeated him, the Shikon Shards were transformed into a 1/2 ball of the original Jewel of the Four Souls.
