Kotaro and Hana were pet otters living with their caring owner in Tokyo, Japan. The family was already accustomed to their shenanigans.
Hana as a girl liked to tease her brother Kataro. She often ate from his bowl which madeKataro very angry. He stared at his sister very angrily and wanted her to be away from his bowl and even toys. However, it didn’t stop Hana to do what she wanted and she continued to tease her brother.
The bothered brother Kataro took his toys away from Hana and Hana came to her owner to ask for some other toys. The owner gave her a stuffed snake with whom the otter played with pleasure.
But in spite of these little fights, the two otters were inseparable.
