The Otherworld Grass is a pale purple plant that appears in the hospital garden of Merea's original world. It is a legendary plant said to connect worlds with its roots and to choose those who will cross worlds. It blooms only after Merea picks it and nurtures it in his hospital room. At his death, it blooms fully, sending his soul to another world. It is acknowledged by the spirits as a real phenomenon. The grass is sentient in a way, as it chooses the person to reincarnate.
