Looking for an older anime. It must have come out before 2012. It was about a wandering samurai who slayed demons.

In episode 1, he visits a cursed child in his home in the woods. The child has a "power" where anything he draws comes to life, but the drawings always turn evil and attempt to harm people or himself. The samurai slays the demon drawings and tells the child to not draw anymore.

In the second episode, he visits a child that has been forced to live in a barn for several days/weeks. The child's eye has been infested by a demon, and the child experiences great pain when in contact with sunlight, so he hides in the barn. The samurai removes the child's blindfold and then kills the parasitic demon, and then tells the child to spend more time in the sunlight to get rid of the pain.
