I am trying to remember the name of this manga about two twin witches, a male and a female duo. The boy has the ability to magically sew together beautiful stuffed animals, whose insides are filled with flowers. After a horrific incident in the town square where many people die, the female twin who is working at the hospital ends up resurrecting the bodies of children who had not been claimed by guardians, becoming filled with flowers, resemblance to her twin brothers' powers. The female twin, along with the children and another male character, then hideaway in a glass orb that holds a tiny world of a house and garden. These little orb 'worlds' are the power of another witch who creates them in exchange for a memory. Of course, the male twin chases after his twin to bring her home. He is also accompanied by the sister, a cop, to the other twin's companion.

I remember the artwork being truly beautiful, ethereal, and simplistic.

Thank you!
