Chi's Sweet Home

Having taken a moment to look up at a bird, a young kitten is separated from her mother. Not knowing which direction home is, she begins to wander around in the hopes of finding her family. After getting nowhere fast, the kitten is taken in by a small boy called Youhei and his family; but as their apartment complex doesn't allow pets, Youhei's parents decide to try and find a new home for the kitten. However, when - after some toilet training problems - they inadvertently name the kitten Chi (meaning pee), Youhei and his parents begin to grow attached and decide to keep her. Will Youhei and his family they be able to keep Chi's presence a secret from the landlady, and will Chi be able to adapt to her new life and surroundings?
