The catchphrases of the series are "Magic, it's a sacred power! Magic, it`s an adventure to the unknown! Magic, and it`s a proof of courage!" (魔法、それは聖なる力！ 魔法、それは未知への冒険！ 魔法、そしてそれは勇気の証！,Mahō, sore wa seinaru chikara! Mahō, sore wa michi e no bōken! Mahō, soshite sore wa yūki no akashi!?) and "Divine! Adventurous! Courageous! It's just MAGIC".
A war between the Infershia and Magitopia had occurred unbeknownst to humans. After being imprisoned within the Earth for fifteen years, the Infershia have returned to get revenge from their imprisonment. When the Infershia attack, five siblings witness their mother change in front of them and she hands them MagiPhones to transform into a magic team. Now endowed with magic powers, these five vow to live up to their family's legacy. They have yet to discover many more family secrets.
These five children (three brothers and two sisters) lived peacefully with their mother, believing that their father died in an expedition in Antarctica. Upon learning the truth, their mother revealed to them their family legacy. Over time, they learn their father was a Heavenly Saint. The five siblings later receive the power to turn into Legend Mode. By the end of the series, the siblings were reunited with their parents.
The youngest of the Ozu Family, he is the Red Magician, Magi Red. He uses his proficiency with alchemy and his power over the element of fire to fight evil. He is headstrong, bold, and sometimes downright stubborn, but he has a brave heart.
The middle son of the Ozu Family, he is the Yellow Magician, Magi Yellow. His specialties are potions and the element of thunder. He is generally quite cynical and sarcastic, and rarely agrees with his family. Nevertheless, he is quite clever.
The youngest daughter and middle child of the Ozu Family, she is the Blue Magician, Magi Blue. Her specialties are fortune telling and the element of water. She later marries Hikaru. She rarely speaks, and sometimes her siblings tease her about being subservient to others. When she does choose to speak, it is usually very important.
The eldest daughter and the second oldest child of the Ozu Family, she is the Pink Magician, Magi Pink. Her specialties are transformations and the element of wind. Flighty and a little ditzy, she considers herself an expert on love, and usually goes out with several boyfriends at the same time. She is also an actress.
The eldest son of the Ozu Family, he is the Green Magician, Magi Green. His specialties are herbalism and the element of earth. He takes his responsibilities as eldest quite seriously, and tries to make sure that his siblings listen to his advice. Frequently refers to himself as nii-chan ("big bro").
After Miyuki disappeared, Hikaru began to teach the Ozu children more about magic, and joined them in battle as the Heavenly Hero Magi Shine. His true identity is that of Heavenly Saint Sungel. His specialties are the elements of light and the sun.
The mother of the Ozu Family, she is the White Magician, Magi Mother. After her husband disappeared, she watched over her children by herself and kept their magical abilities a secret until Infershia started to attack the surface. Her specialty is the element of ice. Was thought to be killed in Stage 2 but later revealed that she was alive.
The long lost father of the Ozu Family, he had defeated Infershia long in the past, but had been transformed into Dark Magic Knight Wolzard(魔導騎士ウルザード,Madō Kishi Uruzādo?) and fought the Magirangers, until regaining his memories and helping them as Wolzard Fire. His true identity is that of Heavenly Saint Blagel. Blagel absorbed N Ma's soul into his body after it was revealed that he was indeed their father. With N Ma's soul in him, Blagel continued to take on the purple Wolzard form, and aided the Magirangers in a fight against one of the Hades Gods, but used the Heavenly saint spell syllables (golu etc.) instead of the usual Uru syallables. When Blagel was defeated by Titan, Miyuki rescued him and gave him magic to become Wolzard Fire.
The Underground Hades Empire Infershia (地底冥府インフェルシア,Chitei Meifu Inferushia?) are from the Kedomono Realm at the center of the Earth, which was ruled by the mysterious N Ma. Fifteen years ago, N Ma created the Hades Gate to send his entire army to Earth, but was stopped by the Heavenly Saint Blagel. N Ma uses his agents to break the seal so he can conquer the surface world. However, over time, some of the Infershians began to realize N Ma's insane obsession of destroying Magitopia and the Ozu Family was reckless due to needless deaths. Once N Ma was destroyed, Hades Goddess Sphinx took over the Infershia to rebuild their world and start anew with Magitopia.
The various characters of Magiranger utilize magical spells to accomplish various tasks. Each magical word correspond to a digit on a phone. For example, when the Magiranger want to transform into their Magiranger forms, they use 106, which corresponds to "Maagi Magi Magiiro." and "Goolu Golu Goludiro."
