This was a good first episode.The story is that two sisters (Yuko Okonogi) and her younger sister move to a new city and their mum is too busy to meet them so they have to get to their house alone.Another girl is chasing after a strange black animal.
Yuko searches for their dog Daisuke who has run off and she acccidently finds and picks up a cyber cat instead.Fumie Hashimoto finds her with the cat and gets her to give it to her and then runs away from the boy and takes the cat with her.
Daisuke finds a strange black creature and runs into a black hole in the wall after it and they have to get it out again.Fumie is asked to take on the job to get the dog out of the hole.
The pet dog is annoying though but the story is interesting and the animation style is not too bad but it takes getting used to.
