Daita Oiwa

"Kirenger!"

Daita Oiwa (大岩 大太) is Kirenger (キレンジャー) of the Gorengers, with the designation number "3". He is a jovial engineering recruit at EAGLE’s Kyushu branch.

Gorenger
While adept in mechanics and mathematics, he had a very hard time solving simple word puzzles and riddles. Being a Judo Champion, Daita was very strong and tough. He had a voracious appetite and often ordered “Omori” (big portions) of everything, especially curry rice, which was his favorite. He is said to have ten siblings.

As Kirenger, he was armed with the “Ki Sticker” &lt;Yellow Sticker&gt; which was a fighting pole whose head can be outfitted with various attachments such as a punching fist. He also utilized the “YTC” radio which could jam electronic circuitry. Oiwa was later promoted to Chief of the Kyushu EAGLE branch.

Daigorou Kumano was recruited from among EAGLE’s other trainees to fill his position. Daigorou, however fell in battle while battling a Kuro Jujigun operative. Daita soon returned to active duty again with the Gorenger team. He rode in the “Blue Machine / Blue Star” sidecar. He also copiloted the “Varibloom” and “Varidreen” sky vehicles.

Manga
In Gorenger's manga sequel, which takes place several years after the defeat of the Black Cross Army. Daita, now no longer Kirenger, acts as a mentor to the new Gorenger team, made up of the children of the former Gorengers, led by Tsuyoshi's son after Tsuyoshi was killed by the remnants of the Black Cross Army. The Gorenger manga is considered to be non-canon, as Akarenger is seen alive several years later alongside his teammates and other Sentai Rangers.

Legend War
Years later, Daita 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, his team's leader, Tsuyoshi Kaijo noticed the fleet moving towards them. He then gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. The Kirenger powers are later utilised by Luka Millfy via the Ranger Keys.

Farewell Space Pirates
After the Zangyack's final defeat, Marvelous returned the Ranger Keys to their original owners. Daita's team leader, Tsuyoshi, was seen seeing the Gokaigers off. It is assumed Daita and his teammates have their powers again.

Super Hero Taisen
Daita, alongside his team, 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.

His uniform also sports a pinup collar, a yellow cape, and  a black belt with the teams "5" symbol as a belt buckle. His helmet is yellow with a black, oblong visor and a silver "3" on the forehead.

Ranger Key
The Kirenger Ranger Key (キレンジャーレンジャーキー) is Daita Oiwa'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 Kirenger Ranger Key was mainly used by Luka Millfy (Gokai Yellow), who used it to fight as Kirenger.
 * The Gokaigers became the Gorengers in their first ever Gokai Change on Earth.
 * The Gokaigers became the Gorengers in their baseball match with resurrected Black Cross Army monster Baseball Mask.

The Gorenger 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. At the start of the battle, the Gorengers had a brief skirmish with the two teams alongside the keys of three recent teams, the Gekirangers, Go-Ongers, and Shinkengers. The Gorengers appeared again after all the other puppets were defeated, with a Gorenger Hurricane ball being kicked at Gokai Red and Super Gosei Red. The Gorengers stood behind the three recent teams who fired their cannons at the Gokaigers and Goseigers, who countered with their team finishers, taking down the three teams as Gokai Red and Super Gosei Red finished off the fake Gorengers.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumbed that Daita received his key and became Kirenger once more.
