Our Japanese friend Asahi devoted his entire youth to his only son Ryoto. But as soon as he turned 18, he moved from his father to Tokyo to study and never returned to visit him.

Years passed... Asahi found out that his son had a family, and his grandchildren were already going to school. The carpenter began to dream about how his family would be reunited again! Exhausted, he accidentally fell asleep... and in his dream, the Dragon appeared to him.

""Do not cry for grandchildren as it is not too late to build strong family ties!"" he said. Asahi woke up and the Dragon immediately disappeared.

On the table, the Dragon left a diagram of a wooden toy. Asahi set to work without hesitation. As soon as the toy was finished, there was a knock on the door. Could you believe it was his family?

Asahi could not believe his own eyes! He told them about the dream immediately and showed them a new puzzle. The children could not solve it on their own, and only with the help of their parents, they succeeded. At that moment, the family realized that they are only strong when they are together.  

Thanking the Dragon for the wise lesson, Asahi named the puzzle "House of the Dragon".
