Summary
As Inuyasha and the others search the ruins of one of Naraku's old castles, Sango finds the graves of her fellow demon slayers. Miroku moves them away from Naraku's castle and gives them a burial in non-defiled soil. As Sango prays at the grave, she vows that someday she and Kohaku will guard their tombs.

Meanwhile, an amnesiac Kohaku skillfully chops up wood for an elderly couple. The couple found him in the woods shortly after Lord Hitomi Kagewaki's castle mysteriously disappeared. That night, Kohaku leaves the elderly couple after he is attacked by Naraku's poisonous insects. Kohaku runs into the woods and is attacked by a huge demon working for Naraku. But he is saved by Sango (the group came running when Kagome sensed a jewel shard), who kills the demon with her boomerang. Sango is overjoyed to be reunited with her brother. Later that night, Sango and Kohaku bond and Kohaku learns a little about himself. Kohaku falls asleep and Sango slips away. Inuyasha confronts Sango and tells her that this has to be one of Naraku's traps. Overhearing this, Kohaku runs away to save Sango the trouble he'll undoubtedly cause.
