Kai Ozu

"The Burning Flame Element! The Red Mage, (Legend) MagiRed!"

- MagiRed's role call

Kai Ozu (小津 魁) is the youngest of the Ozu Family, he is the Red Mage MagiRed (赤の魔法使いマジレッド) of the Magirangers. He uses his proficiency with alchemy and his power over the element of fire to fight evil.

Design
He wore red spandex with a short red cape, which was an outline for a large "M", which went all the way down to his boots. His belt buckle was in the shape of an "M" also. His helmet bore the symbol of the Phoenix.

Magiranger
17 years old (23 in Gokaiger) and the youngest of the Ozu siblings, Kai is a Red Mage, a wizard who has power over the Burning Flame Element (燃える炎のエレメント). Despite being the youngest, he still follows the tradition of his fellow Red Rangers of being the team leader. He's a sophomore student who is into soccer and bickers often with his older brother Tsubasa.

His straightforward and impulsive behavior often leads to him making mistakes, but Kai is kind at heart and very brave for his age. He hates to be babied and wants to be treated like an adult, though his frequent bouts of impulsiveness and naivete often bar him from being treated like a mature adult. He was most upset about his mother's apparent death at the hands of Dark Magic Knight Wolzard, and swore vengeance for it, until he learned that Wolzard was his father.

During the course of the series, he inherits many of Isamu's techniques, mainly his "Blazing Storm" and lives by his father's saying "Chance is something you make yourself."

His primary attack is "Red Fire", where his body is engulfed in flame creating a Phoenix image which burns any adversary it flies through. As Red Mage Legend MagiRed (レジェンドマジレッド), Kai's "MagiBolt" summons a torrent of fire, which is more powerful than Red Fire.

In the special "Tokusei Magiranger Special", Kai drops his MagiPhone into the Mini Garden Spring while dueling with MagiShine and the Goddess of the Mini-Spring gives him the option of getting either a Silver MagiPhone or the Golden GripPhone and so he lies to gain the Golden GripPhone and with it, the ability to become Heavenly Hero KaiShine (天空勇者カイシャイン). As KaiShine, he wears MagiShine's armor, with a red neck scarf in place of MagiShine's flowing golden cape. However, he accidentally transforms himself into a duplicate of Hades Beast Spider and since he lied to get the Golden GripPhone, its magic is closed off to him. Fortunately, the Goddess of the Mini-Spring is able to use magic to restore him when he pledges to never be dishonest again and his normal MagiPhone is returned to him.

At the end of the series, he becomes a sort of a liaison between the "Surface World" and Infershia. He also now dresses in his father's traditional Magitopian robe and which implies that he will carry on his father's legacy as a great warrior of magic. AkaRed in GoGo Sentai Boukenger vs. Super Sentai transformed into MagiRed and fought against Chronos, Duchess Org Tsuetsue, Sorcery Priest Meemy and Arch Priest Gajah.

Also, In the Special "Mahou Sentai Magiranger vs. Dekaranger" it is shown that Kai carries a picture of Yuka Yamazaki, whom he loves, in his Magiphone. When Ban asked him that if, in ten years on the next Fantastic Happy Day, they themselves would have families of their own.

Legend War
A few years later, Kai fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders. AkaRenger noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada.

Man in black
When the Gokaigers landed on Earth, their guide Navi told them to find "A man dressed in black". This man turned out to be none other than Kai, now 23 years old and calling himself "A magician who has forgotten his magic" and challenged Gokai Red and Gokai Green.

Kai helped Gokai Green realize the "true power of the Magirangers", which turned out to be courage. He revealed to Marvelous that he could only gain the Greatest Treasure in the Universe once he unlocked the Greater Powers of the Ranger Keys.

Farewell Space Pirates
After the defeat of Ackdos Gill, Captain Marvelous returned all the Ranger Keys to the former Sentai heroes. Since his older sister Houka got her powers back, it is assumed he got his powers back as well.

Super Hero Taisen
Kai, alongside his team (MagiShine, MagiMother, and Wolzard Fire were absent), among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker.

Zyuohger vs. Ninninger
MagiRed appears as part of a conference of the first 38 Reds whom address the Ninningers and Zyuohgers.

Chou Super Hero Taisen
MagiRed fights as part of the Super Sentai Red Warrior Team.

Personality
During the series goes, Kai initially childish and mostly screw the fight. As the series goes, he matured little by little and also admit the existence of his father which he refused at the first time due he was still baby when his father left him. But as the leader of his team despite the youngest, he does show his leadership in pinch situation to never give up as he is the bravest member of the team.

His personality turned into completely mature in Gokaiger as he calmly faced Marvelous and Don on his challenge.

Hand-Off
MagiRed was the first Sentai Red to have a Hand-Off from his predecessor and to his successor. MagiRed appears before DekaRed, by a stark black background through a spark of fire. Both Rangers give each other a high five, and turn their attention toward the viewers.

MagiRed (outside) calls Bouken Red (black background) through his MagiPhone. Through a split-screen effect, Bouken Red turns his attention toward the viewers, posing. This is, so far, the only Hand-Off where the two Reds do not physically meet one another, with MagiRed instead making phone contact with Bouken Red (Satoru Akashi) from a different location. This is also the only Hand-Off between two Reds who did not meet up in a subsequent team-up focused exclusively on their teams' meeting (ie. not counting the Legend War, where they did not interact with each other anyway).

Ranger Key
"Magiranger!"

- Mobilates' Gokai Change announcement

The MagiRed Ranger Key (マジレッドレンジャーキー) is Kai Ozu's personal Ranger Key and what became of his powers after he, along with the rest of the 34 Super Sentai, sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The MagiRed Ranger Key was mainly used by Captain Marvelous (Gokai Red), who used it to fight as MagiRed. It was also used by Gai Ikari (Gokai Silver), Luka Millfy (Gokai Yellow) and Ahim de Famille (Gokai Pink) on several occasions.
 * Ahim became MagiRed as part of an all-red Gokai Change when the Gokaigers traveled to the past and fought against Shitari of the Bones and his Gedoushu during the Goseigers' team-up with the Shinkengers.
 * When the Gokaigers became the Magirangers in their fight with Action Commander Shikabanen and his Zangyack force.

The Magiranger keys, along with all the Ranger Keys of the first 33 Super Sentai, were briefly taken by the Black Cross King and turned into Ranger puppets that were fought by the Gokaigers and the Goseigers. Splitting up, the puppet MagiRed was defeated as part of a group of surviving Red warrior keys by Gokai Red and Super Gosei Red.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Kai received his key and became MagiRed once more.
