this is a 4 panel screen which Lord Kaya keeps in his collection, Lord Kaya is the master of Ayana, from the last upload.
The story goes that the four mermaids showed here all became immortal, its also believed that they were not really mermaids, but just girls who lives by the water. The flower symbolized the temptation of immortality, and the way they look at the flower, reflected their response to the temptation. the story ends with the girls turning against each other, subsequently splitting the land into factions and into war.
Lord kaya treasures this a lot, one of the reason being that Cielo was supposed to be one of the mermaids, an immortal girl which he searches for.
