Lizard demon

The is a weak yōkai who, imposed as Satsuki's brother, tricks her into giving him her Shikon Jewel shard. Fortunately, Shippō and Inuyasha save her before she is harmed.

During the story
This lizard demon actually appears before she poses as Satsuki's brother. Miroku, as he often did, entered the lavished dwelling of the headman and told him that he sensed a demonic presence. Inuyasha and the others believed that Miroku was merely lying to the man and intended to perform a fake exorcism as he normally would, in order to ensure that they had food and a place to sleep for the night. Much to everyone's surprise it turns out that Miroku was actually telling the truth this time, and he easily exorcised the lizard demon from the headman's home.

The lizard demon is seen soon after, vowing that he will get retribution for being exorcised from the headman's dwelling; he says that he will use Satsuki to reach these means.

Soon after, when Satsuki is at home, her brother, who everyone in the village knows to be dead, appears and she happily welcomes him home. Shippō arrives soon after and realizes that he is actually the lizard demon in disguise. The demon threatens to kill Satsuki is Shippō doesn't bring him a real shard of the Shikon Jewel. Using his fox magic, Shippō reveals the true identity of the imposter. Shippō and Satsuki manage to escape but the lizard demon soon gives chase, destroying Satsuki's home in the process.

Shippō helps Satsuki escape from the demon and plans to fight the lizard off by himself. The lizard demon reveals that he used Satsuki in order to get to Shippō, to take him as a hostage as a means of getting a shard of the Shikon Jewel from his friends. Shippō continues fighting the lizard demon, but is unable to do much damage to the demon besides biting it. Just then, Inuyasha arrives on the scene. Inuyasha thinks that this would be the perfect opportunity to try out the Backlash Wave, but soon realizes that the lizard demon's demonic energy is so weak that he can't even use it. Inuyasha then angrily punches the demon out, causing it to revert to a much smaller form; Miroku soon arrives and pins the lizard to the ground with his staff and realizes that this is the same demon he had exorcised before.
