Keiichiro Asaka (朝加 圭一郎 Asaka Keiichirō) is Patren 1gou (パトレン1号 Patoren Ichigō), the Red Ranger of the Patrangers.

Briefly transformed into a woman by Pitch Cock, Keiichiro was renamed Keiko Asaka (朝加 圭子 Asaka Keiko). Tvicon.png TV STORY-Number 11: I Will Continue Shooting


A member of the Global Special Police Organization Japan Branch, Keiichiro Asaka was assigned as part of a three-member tactical unit established to counter the Interdimensional Crime Group Gangler. On their night shift, the three officers were sent to shut down the illegal casino of Gangler Monster Ruretta Gerou, only to be beaten by the notorious phantom thieves, the Lupinrangers. On the following day, the Tactical Unit were alerted by accountant robot Jim Carter to a Gangler incursion at the Kurehama Pier, which coincided with their receiving of the VS Changers, devices provided to counter the Gangler, by Commander Hilltop. Confronting the Gangler whom they found engaged in a fight with the Lupinrangers, the three GSPO officers, intending to arrest all parties, used the VS Changers to transform into the Patrangers, with Keiichiro becoming Patren 1gou. Tvicon.png TV STORY-Number 1: The Troublemaking Phantom Thieves

In the ensuing battle, Nargo took his leave as the two Sentai fought, with the Lupinrangers eventually taking off in their enlarged Dial Fighters, with Lupin Red's Red Dial Fighter successfully eluding Patren 1gou's Trigger Machine 1gou. Once Nargo returned to wreak havoc, the Lupinrangers reclaimed his Lupin Collection piece and were content to leave him to the Patrangers, but when he was revived and enlarged, they boarded their Dial Fighters to face him. Assisted by GoodStriker, a sentient piece of the Lupin Collection whom initially appeared on the Patrangers' side, the Lupinrangers found that they could use his power to combine their Fighters into the Kaitou Gattai LupinKaiser, allowing them to destroy the Gangler Monster once and for all. Taking their new friend, named "Goodie" by Umika, back home to the Bistrot Jurer, the three thieves were met by the Tactical Unit officers.

Oblivious to the thieves' identities, the officers intended to eat at the Bistro but were called away before they could order. Confronting Namero Bacho, the Patrangers were again met with the Lupinrangers, with the situation being further complicated when Patren 2gou lost his VS Changer to Lupin Blue before being immobilized by Namero's adhesive while his Changer was retrieved by 3gou, allowing the Gangler to get away. While Keiichiro scolded Sakuya for incompetence, Hilltop suggested that he make up for it as an anonymous eyewitness pointed the GSPO to Studio Bacho. Unbeknownst to the Patrangers, they had been used as bait by the Lupinrangers, who moved to acquire the Qui a faith qui as the police officers were all incapacitated upon entering the studio. However, Sakuya proved his worth by freeing himself and his team who, catching up with the Gangler, were met by GoodStriker, who used his power to combine their Trigger Machines into the Keisatsu Gattai PatKaiser for the first time, allowing them to destroy the enlarged Namero, at which point they were ejected as GoodStriker took his leave. Their work for the day done, the GSPO officers resumed their dinner date at the Bistrot Jurer. Tvicon.png TV STORY-Number 3: Take Them Back No Matter What

Super Sentai Strongest Battle

Battle1: Who is the Strongest in History!?

Keiichiro was working late at GSPO one night when he received his invitation to join the Super Sentai Strongest Battle. He became a member of Serious Team and proceeded to fight with Yamato Kazakiri in the first round. After Yamato learned that Keiichiro’s wish is for world peace, he called a truce and the two of them sat down to talk about their wishes. Learning about Yamato’s wish, Keiichiro lets Yamato win the match and salutes him before disappearing.

Saber + Zenkaiger: Superhero Senki

Though he was seemingly erased alongside his team as a result of Asmodeus’ manipulations, he and, presumably, his corresponding team were restored back into existence once Touma Kamiyama had helped Shotaro regained his passion in drawing out the superheroes that he wants to draw out.

During the climatic final battle itself, he can be seen fighting alongside Riderman, OhRed, DekaRed and Kamen Rider Hibiki.


"We've been given the power to protect people, and we mustn't misuse that power. I remember! This isn't about protecting my pride, but to protect public safety, and upholding peace!"
―Keiichiro's resolve as part of the Global Police[src]

Keiichiro is a passionate police officer who takes his job as a cop seriously. He's also hot-blooded as he's usually short tempered (mainly because of either the Lupinrangers or Sakuya's laid-back demeanor), to the point that Sakuya told Keiichiro once that he has a scary face. This however has not stopped him from quietly backing down in front of a suddenly burning Sakuya.Tvicon.png TV STORY- Number 27: Dancing Afterwards

Unlike Sakuya and Tsukasa, who have a rather optimistic and indifferent view on the Lupinrangers respectively, Keiichiro is very pessimistic and negative towards them, only seeing them as thieves and nothing more, despite them also fighting the Gangler. However, after hearing first-hand of Lupin Red's motives to become a phantom thief, Keiichiro became determined to unmask the latter. This seemingly hasn't changed the fact he is very hostile towards him, until the Lupinrangers show their true selves.

Keiichiro is able to give compliments if someone does their best. He is able to prioritize defeating Ganglers first and protecting citizens safety in order to uphold peace for them. Keiichiro holds a fondness for little children (e.g Sota) and tries to do his best to put them at ease, naturally smiling while doing so. However, it has been quoted by Tsukasa that children don't necessarily like him back.Tvicon.png TV STORY- Number 14: The Fabricated Trap

Keiichiro's motivation to become a police officer stems from his childhood. He was annoyed by the fact there was a criminal in a park and makes everyone scared, so he armed himself to catch the culprit. That's when a police officer manages to convince him to leave a criminal to the police and successfully apprehend the criminal to maintain public safety, which moved Keiichiro. This results in him being unable to yield even when he's in grave situations. This is shown explicitly when he gets badly poisoned by Togeno's trap, but he was still able to find Trigger Machine Crane, defeat a giant Odordo, and push through until succumbing to the poison. When he was bed-ridden, he continued to fight Togeno upon hearing that the Gangler is still on the loose, and finally defeats him with the help of his comrades. Even Kairi can't help but admire his resolve and determination as part of the Global Police.Tvicon.png TV STORY- Number 15: The Work of a Police Officer

However, due to his mission-stricken attitude, Keiichiro became somewhat lacking in common sense. He also admits that he is really awkward when he's with a woman that is a possible love interest, much to Umika and Sakuya's annoyance.Tvicon.png TV STORY- Number 17: Secret Feeling

He is not completely heartless, as seen when Sakuya was depressed in the aftermath of the Pyodor fight, he went with GoodStriker's comment of him losing weight in the ordeal to somewhat cheer Sakuya up.Tvicon.png TV STORY- Number 27: Dancing Afterwards

Still not yet discovering Lupin Red's identity, Keiichiro starts to vaguely trust the thief even after admitting to Hilltop that he has "given away" a VS Vehicle to Lupin Red (in reality, it was intentionally stolen by Lupin Red) to finish off the enlarged Kunks Butylmercaptan, in which he responds that it is a good decision.Tvicon.png TV STORY- Number 30: The Two Are On a Trip But it still takes a lot of effort to talk him into working with the Lupinrangers, the subject of which, he can be completely unreasonable to an extent for extreme measures to be taken for an agreement. Upon dueling with Noel Takao, who wants the Patrangers to work with Lupinrangers, Keiichiro learns from Takao about the true purpose of the Lupinrangers, to retrieve the remaining pieces of Lupin Collection in order to restore their loved ones, leaving him to wonder about the thieves.Tvicon.png TV STORY- Number 32: A Request For A Duel This prompts Keiichiro and the Patrangers to discover more about Lupinrangers by researching about the loved ones of the thieves. In special cases, he won't show hesitation in teaming up with the theives. Keiichiro later finds out the real identities of the Lupinrangers, which were ironically proven true by Dogranio. Despite this, he and the Patrangers help the phantom thieves to battle the Gangler, claiming this as Special case, as a way to make up for letting his anger blind him from figuring it out before to give assistance.

After the defeat and the arrest of Dogranio Yaboon, Keiichiro is surprised and relieved about the return of the Lupinrangers. However he questions Kairi and others whether they are still thieves after having their loved ones back. Not being satisfied by his reply, he gains a rivalry (now a friendly one) towards Kairi during their last encounter against the remaining Ganglers.

Upon meeting with Yamato Kazakiri (Zyuoh Eagle), Keiichiro initially refuses to fight against his predecessor out of his respect, but he proceeds to fight him. However, Keiichiro's wish is for a peaceful world, in which Yamato calls a truce with him.

  • to be added


  • Keiichiro is portrayed by Kousei Yuuki (結木 滉星 Yūki Kōsei). As a child, he is portrayed by Ryui Ushio (牛尾 竜威 Ushio Ryūi). As Patren 1gou, his suit actor is Masashi Takada (高田 将司 Takada Masashi).


  • Like several past Sentai Reds, Keiichiro has the word "aka" (lit. "red") in his name's pronunciation to signify that he is the Red Ranger.
  • There is an obvious height discrepancy with Keiichiro and Sakuya Hikawa/Patren 2gou between their civilian and Sentai Ranger forms. Due to height discrepancies between the actors and suit actors, when transformed, Patren 1gou is taller than Patren 2gou while Sakuya is taller than Keiichiro in civilian form.
  • So far Keiichiro is only Patranger who has not piloted any X Trains.
    • Likewise, he is the only core Patranger to ever open Gangler monsters' safes using Dial Fighters during the series run.
    • In addition, he is the only Patranger that does not used any Kaitou Boost on himself.
  • Keiichiro is the only Patranger to use all four auxiliary Trigger Machines.
