Hanabatake is the sole denizen of the lonely area known as the Flooded Garden. She resembles the black-haired girls of Yume Nikki's Witch Island, as well as the Viscera Girls of the fangame .flow. Her name literally means "flower garden."
This NPC could possibly be the gardener tending to the Flooded Garden. She reacts only to the Match effect; she can be burned to a crisp and disappear. Otherwise, she is a largely unresponsive NPC.
