Watari Kappa is a Japanese kappa that used to live in a small pond in the mountains. Life was the same day after day, and Watari Kappa couldn’t stand monotony. One morning, a mysterious traveler appeared at the pond and told her many stories of his trips.
Watari Kappa decided to leave the pond to explore the world, and even though her friends told her she would find many dangers outside the pond, she took courage and embarked on a new adventure in which she would meet many new friends.
