- ―Kirenger's roll call[src]
When the Black Cross Army launched an assault on the EAGLE bases in Japan, a force led by Bronze Mask attacked the Kyushu base, slaughtering everyone with only Oiwa surviving. Along with the survivors of the other bases, Oiwa was summoned to Snack Gon, the secret gateway to EAGLE Japan's main command center by Japan's EAGLE Commander Edogawa Gonpachi. There they were given special formfitting electronic battlesuits, which empower its wearer with various superhuman abilities. Edogawa told them that they are the Secret Squadron "Gorenger", the world's best chance against the forces of the Black Cross Army. Their first battle was with Gold Mask, who they destroyed with the Gorenger Storm.
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 later fell in battle while battling a Black Cross Army operative. Daita soon returned to active duty again with the Gorenger team.

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 utilized by Luka Millfy via the Ranger Keys.

The Kirenger Ranger Key (キレンジャーレンジャーキー Ki Renjā Renjā Kī) 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. Daita received his key and became Kirenger once more.
Behind the scenes
Daita Oiwa was portrayed by the late Baku Hatakeyama (畠山 麦 Hatakeyama Baku). As Kirenger, he had several suit actors: Naotaka Maeda, Kōsaburō Tanaka, Masato Amano, Kōji Ueda (Episodes 1-60), and Yutaka Tatebe (Episodes 61-84).
Kirenger has one leitmotif, entitled "Oidon Ookui Kirenger".
- Daita is the original Sentai Yellow Ranger.
- He was temporarily written off the script because Baku Hatakeyama had a schedule conflict with a play he was doing. Daigorou Kumano was then to be a temporary replacement.
- Daita Oiwa is the first Sentai warrior whose actor (Baku Hatakeyama) is currently deceased. Because of this, Kirenger was voiced by Tomokazu Seki in Gokaiger Goseiger Super Sentai 199 Hero Great Battle and Super Sentai Battle: Ranger Cross, and he didn't appear detransformed. He is followed by Tatsuya Nomi who played Daigo of the Heaven Phantom Star (ShishiRanger) in Gosei Sentai Dairanger.
- Strangely, Kirenger is seen in a Yellow Megaforce Ranger card in previews for the Power Rangers Action Card Game Series 3, Universe of Hope.   His appearance is unexplained.
- Daita Oiwa is absent from the only Gorenger movie not actually an episode from the TV series, Himitsu Sentai Gorenger: The Bomb Hurricane.
