Mahou Sentai Magiranger (2005)

Forces from Infershia attack the surface world in order to resurrect N Ma, their emperor. Through their mother, the five Ozu Siblings discover that they are magicians chosen to defeat the Earth from this evil. After their mother's "death", the siblings discover a room in their home hidden by magic, and with it Mandoraboy--a Mandrake being who guides the Rangers in their fight to save Earth, and later Magitopia, from Infershia.
