Shingetsu no Nazo: Kurokami no Inu-Yasha
Mystery of the New Moon and the Black Haired Inu-Yasha
Hojo, Kagome's friend from school decides to ask her out on a date and Kagome accepts. Afterwards, Kagome meets up with Inu-Yasha, Myoga and Shippo to find the next Shikon shard.
As they are sailing along a river, they see a girl falling from a cliff. Inu-Yasha manages to catch her, and she tells them her story. (After she expresses how much she hates demons) "Demon! Unhand me!"
Her name is Nazuna and her village has been attacked by spider demons. The group offers to help, but Nazuna flatly refuses them. She then atempts to climb back up the cliff to the village but falls and injures herself.
They take her home and meet the old monk who has become her surrogate father. The monk asks them to spend the night and they accept, much to Inu-Yasha's dissapointment.
As night falls Inu-Yasha begins to get fidgety and goes off by himself. Just then he notices that the Spider demon's have them completely surrounded and has the monk captured. Shippo, Myoga, Kagome, Inu-Yasha and Nazuna manage to escape when Kagome notices that Inu-Yasha's hair is black and his ears are gone. Myoga tells her Inu-Yasha's secret.
When the new moon comes every month, Inu-Yasha loses all his demonic powers and reverts completely to a normal human being. Kagome realizes she's left the Shikon shards back in the temple so Shippo and Inu-Yasha return to get the shards and try to save the monk. Once they arrive, they see that the monk is actually the spider demon. Kagome and Nazuna arrive just in time to get the injured Inu-Yasha into a safe room to spend the night.
Myoga saves Inu-Yasha's life by succing the venom out of his neck. Kagome and Inu-Yasha share a few romantic moments before the demon attacks and devours the Shikon shards. Kagome figures that the venom went to his head and doesn't know what to think. Inu-Yasha is about to be finished off as the sun rises and he reverts back to his true self. He quickly kills the spider and everyone is surprised to see that the Shikon shards fused together inside the demon to create a large half-completed jewel.
