My name is Fiore (フィオレ), and I'm an alien. I fly around space alone.
I visited earth in the past, and met Mamoru at a hospital. But my body couldn't survive on earth for a long time, so I had to leave. Mamoru gave me a flower as a parting gift, and I promised him that I would return with some flowers for him.
While in space, the evil flower Kisenian took over my weak mind, and I returned to earth to destroy all life there.
