East Garden, Ancient Yamada Manor, Sakura City.
As the place was enormous, therefore it was natural to have more than one garden in the manor. The East Garden in particular differed from the others with its golden, purple, and black flowers and Sakura trees.
Hazel designed this garden in honor of her husband and daughters.
Purple came from the Ezume, Ayia, and Kaori hair colors.
Golden came from her own hair color.
And Black from Shizuka's hair color.
She especially ordered black, golden, and purple sakura trees to plant in the garden.
It was her favorite place in the manor, and the same happened with the others. They could feel Hazel's feelings when they were in this garden.
That's why this was the place they chose to have tea when they finished their lunch with the rest of the family.
