InuYasha and his companions pursue Naraku into the Netherworld, finding themselves at the grave of Inu no Taisho. InuYasha hallucinates to when he was attacked by demons as a child. The deceased Hosenki shoots a multitude of adamant (diamond) spears at InuYasha and his companions from the grave, where the last shard of the Shikon Jewel has been located. Hosenki prophesies that many shards of the Shikon Jewel have become tainted, whereupon he must not let anyone get a hold of the last shard of the Shikon Jewel, as that may also be tainted. Hosenki is corrupted by the last shard of the Shikon Jewel, drawing evil from the presence of tainted shards of the Shikon Jewel nearby. InuYasha plummets into the abyss after being brutally attacked by Hosenki.
