"You see... he may always look happy, but he cries easily. I know that...because I have the same heart as him."
―072's last words[src]

Roidmude 072 (ロイミュード072 Roimyūdo Zero Nana Ni) was a Plain Bat Type (バット型 Batto-gata) Roidmude. He took the human form of the Special Investigation Unit's researcher, Kyu Saijo (西城 究 Saijō Kyū) and has been secretly switching roles with him since Episode 13.


Character History

Around New Years, Kyu was searching information about the Kamen Rider, until 072 came out of his computer and tried to dispose of him after copying his memories. After his last request before dying was to watch that night's newest Murmur Mansion episode, 072 became emotional about the show and realizing similar interests, the two became friends. Whenever Kyu had himself busy, he would asked for 072's help to replace him.

The clone had actually been present multiple times in the series, once during the Slowdown Wristband case and the other on Voice Roidmude's marriage scams.

One day, when an idol announced that she would be voicing a part in the anime that 072 and Kyu watched together, he attempted to kidnap and lecture her, only to be distracted by the appearance of Drive and Mach, who were thinking 072 was going to kill her. During their conversation, two Reaper Legion Roidmudes appear in an attempt to execute 072, but he manages to escape.

He later appears before the Investigation Unit alongside Kyu, which they revealed that 072 took his place during work while Kyu was not available in the past. After they find out which one he is, Shinnosuke and Kiriko talk to him. Shinnosuke allows 072 to live after seeing similarities between him and Chase, realizing that Roidmudes can become good, even by accident.

072 Death

072 is stabbed through the chest by Medic's tentacle.

He was however killed by Medic and dies in front of Shinnosuke and Kiriko, to which Shinnosuke would try to avenge his death, only for her to use the Reaper Legion Roidmudes as scapegoats. Before he died, 072 asked him to tell Kyu that he went crazy and that the Kamen Rider defeated him, as he knew that Kyu would be a bit emotional and obsessive at times, due to him copying his memories. When Did Kyu Saijo Become a Roidmude?


Kyu 072 relationship

Kyu's connection with 072 is exploited by Nira and "Noumi".

Mirroring Shinnosuke, Medic lied about the nature of 072's death, telling Heart that he was destroyed by the Kamen Rider alongside her Reapers. Despite his death, 072 in the end would unintentionally left a big help for the Special Unit. Kyu revealed to the Special Investigation Unit that Roidmudes could travel through computers using their Cores, realising that 072 had found him via his blog. Kyu could now use his method to track Roidmudes via computer network, an alternative to relying on reports of Heavy Acceleration. What Can Be Spoken About the Irregular Dead? While Kiriko pursued Chase to return to their side, she tried to convinced him that not all Roidmudes are evil, and Kyu approached himself from his hiding, where he confirmed Kiriko's words as he still acknowledge 072 as his friend, despite being "informed" that he turned mad before his death. Why Has a New Battle Started?

In a plot to ensure the death of Eisuke Tomari remains a secret, Mitsuhide Nira and Sou Noumi/Brain held a conference where they falsely accused Kamen Rider Drive for trying to takeover the leadership of the Roidmudes while the Special Investigation Unit were framed using their relations to past Roidmudes, among them were Kyu's relation to Roidmude 072. Why Did the Siege Happen?

When an angry Heart confronted Medic about her Over Evolved experiments which had been harming fellow Roidmudes, he revealed that he was aware this was not the first time she had hurt their friends, alluding to her murder of 072. Who is Aiming for the Ultimate Taste?

072 was evidently the inspiration for Kyu's best-selling novel, Mechanical Friendship, which he wrote following the retirement of the Special Investigation Unit with the defeat of Tenjuro Banno and the extinction of the Roidmude race. Who Will You Entrust the Future to, My Friend?

The 108 Roidmudes' fragmented data would lead to the emergence of the amalgamation Roidmude 5886. Kamen Rider Drive Saga: Kamen Rider Heart


After scanning Kyu Saijo's mind, 072 has a mutual interest on the same things Kyu had. Like Kyu as well, he is also portrays comical tendencies and tried his best to live peacefully. Still like his template, he would try to lecture anyone who would offend his interests, though as a Roidmude, he has more power to reach his objectives.
