“ | My brilliance... and research... are the only things of value. They are the truth of this world! | „ |
~ Ryoma Sengoku while being confronted by Kaito. |
Ryoma Sengoku is a researcher for the Yggdrasill Corporation who created the Sengoku and Genesis Drivers and one of the main antagonists of Kamen Rider Gaim. With his Genesis Driver, Ryoma has the ability to transform into Kamen Rider Duke by inserting the Lemon Energy Lockseed.
Ryoma works under Takatora Kureshima, the head of Yggdrasill's research and development branch. Unbeknownst to Takatora, Ryoma is secretly plotting to overthrow him and use the Helheim Forest situation to claim power for himself.
Ryoma later returns as the secondary antagonist of the Gaim portion of Movie War Full Throttle, having been revived by the Megahex collective to assist it in assimilating Earth and Helheim. Ryoma also appears as a supporting character in Kamen Rider Gaim Gaiden: Kamen Rider Zangetsu, a background antagonist in Kamen Rider Gaim Gaiden: Kamen Rider Baron, and the main protagonist of the V-Cinema film Kamen Rider Gaim Gaiden: Kamen Rider Duke.
He was portrayed by Tsunenori Aoki.
Personality[]
Though appearing outwardly friendly, Ryoma is in fact an egotistical sociopath motivated by a desire to use the Helheim Forest to become a god and rule over the world. Like the other members of Yggdrasil's inner circle, he treats the Beat Riders as nothing more than guinea pigs to test his inventions and stepping stones to advance his own agenda. Ryoma doesn't even care for the lives of his own allies, being perfectly willing to send them to their deaths to ensure his own survival, such as when he sent his own bodyguard Marika and a handful of Kurokage Troopers to hold off Demushu while he escaped. Though he possesses tremendous power as Kamen Rider Duke and is a fairly skilled fighter, Ryoma is very cowardly and prefers to only enter fights that are clearly in his favor. To maintain his advantage over the other New Generation Riders, Ryoma installed kill-switches in the Genesis Drivers to prevent them from being used against him.
In addition to being extremely intelligent, Ryoma is very prideful about himself and his inventions, viewing his creations and research as the only things of value and the only acceptable means for humanity to evolve. As such he is outraged whenever someone manages to obtain a powerful state that is not due to his inventions. Despite this, Ryoma is a very effective manipulator and was able to keep Takatora in the dark about Helheim's Over Lords as well as his splinter group, having usurped Takatora's leadership in Yggdrasill in all but name.
What Makes Him Pure Evil?[]
- Aided Yggdrasil in experimenting with Lockseeds on children and felt no remorse for their deaths.
- Created the Sengoku Drivers which is part of what disrupted the peace in Zawame city due to the fighting it brought.
- Felt livid at the fact Takatora didn't "understand" him so he plotted against him by manipulating him into a spot where he could be killed.
- Killed Touka Akatsuki to rid any evidence of Amagi Kureshima crimes and revealed he actually initially killed the latter.
- Gave dangerous Sengoku Drivers to other individuals just so he could collect data and didn't care what ultimately became of them, like a butler who turned into a mindless Inves.
- Made Kaito join his splinter group and further fueled the latter's Darwinistic impulses.
- When the Over Lords were discovered, he kept it a secret from Takatora then lured him to a strategic point where he could be assassinated.
- Wiped Takatora from Yggdrasil's databases out of spite.
- When he was "heroic", it was pragmatic and when the invasion of Redyue and Micchi began, he fled and left Zawame in shambles.
- When he helped later, it was to observe Kouta's growing power and to obtain the Golden Fruit, pitching in only when absolutely necessary.
- His system was revealed to spying on everyone for his own benefit and, after Redyue's death, used the opportunity of knowing who Roshuo gave the fruit to, so he could obtain Mai.
- Trapped the other two friends in a room as he essentially dissected Mai for the fruit and told Micchi it was nothing personal.
- Gave Micchi a dangerous Lockseed that was sealed away for killing its user after one time usage, and coerced him into fighting Kouta and the latter soon died.
- Felt no remorse in lying to Micchi and began to beat, torture, and kick him after he had served his uses.
- After Mai became the Woman of the Beginning and lost the fruit, he fought Kaito and Yoko but shut off their Genesis Drivers.
- Even at death, he displayed his egotism claiming only his inventions should be recognized, as he was not amused by Kaito's transformation into the new Over Lord Inves.
- After he was revived by Megahex, he gladly joined with his plan to assimilate everything. but did everything out of pragmatism and a newfound idealistic standpoint.
Trivia[]
- His actor Tsunenori Aoki faces even more criticism than Ryoma when he was arrested in Setagaya Ward after getting drunk and then molesting three unknown women from behind.
