Rosyuo

"We are Femunshinmu. We are descendants of the people who once flourished in this world."

- Rosyuo's introduction in front of Takatora

Rosyuo (ロシュオ) is a White Over Lord Inves and is responsible for countless murders of the old civilization trapped in the Helheim Forest, and has targeted Japan next. He is also the previous individual chosen by the Helheim Forest, and holds the Forbidden Fruit of his realm.

His motive for everything is apparently caused by the results of his actions of making a Social Darwinist state into a reality, which destroyed his civilization, and making him outlive his wife.

He isn't aware that Redyue has been planning to steal the Forbidden Fruit he guarded behind his back.

History
Nothing is really known about Rosyuo outside of Redyue's implications that he is their superior when he tried to drag Demushu away from his fight with Kaito Kumon.

Rosyuo later ordered Demushu to stop attacking humans and retreated. However, Demushu kept disobeying it. Having no other choice, Rosyuo telepathically called him to cause pain to Demushu, making the Red Over Lord Inves retreat.

He later punished Demushu for disobeying his orders.

"This forest puts the test to those who takes the challenge. To pick one person who is worthy to rule this world. But everything we did was a mistake."

- Rosyuo explaining to Takatora about the existence of Helheim

Rosyuo saved Takatora as he informed him about his origins. Rosyuo revealed the Helheim Forest was a civilization called "Femushinmu". He also tells that their civilization happily accepted Helheim and he was chosen by the Helheim to become the king. However, everything didn't turn out as he expected, as he had set the world into a Social Darwinist state. As shown, Demushu and Redyue killed their own people, showing the surviving strong had turned on each other. Rosyuo felt really guilty of what happened to his civilization and knows that the humans also will make the same mistake like him. Because of that, he won't give the forbidden fruit to anyone.

While informing Takatora about the Helheim's origins, including about his deceased wife, DJ Sagara appeared in front of Rosyuo to inform that Demushu has recklessly struck Zawame City. Sagara also told Rosyuo that he has been cheating for having two forbidden fruit and suggested to give one of the forbidden fruit to the humans. Rosyuo then relinquished the forbidden fruit he guarded from his hand and turned it into the Kiwami Lockseed, giving it to Sagara to give to the rightful person to be its guardian.

Spotting an uninvited guest, Sid, Rosyuo shows how willing he is to prevent humanity from succumbing to the same mistakes as his own civilization by killing Sid, deeming him unworthy to have the forbidden fruit due to his foolish intention to use the forbidden fruit for his own selfish purposes.

Later, he allows Redyue to continue the invasion of the Earth, which shocked Takatora a lot.

Redyue later brings a laptop to show Rosyuo about how advanced humans are. Redyue also said that with Earth's technology, they can revive the Queen. With this, Rosyuo orders his subordinates, Grinsha, to help Redyue. Rosyuo later tells Takatora that he knows that Redyue wants his forbidden fruit but he decided not to take any offense. Because, what he wants is just to revive the Queen and if he can revive the Queen, then he will have no need for the Fruit of Knowledge. As Rosyuo and Takatora emerge from the Crack into the Yggdrasill Headquarters. Rosyuo senses that missiles are being targeted at Zawame City. Before the missiles successfully hits the city, Rosyuo stops the missiles and reduces them into a ash with a single slash. Making most of the Riders realize how powerful one can be with the Fruit of Knowledge.

Personality
It seems that Rosyuo is sort of like an authority with the Over Lord Inves. He is however trying to revive the mysterious Over Lord Queen who acts like a King. It was revealed that despite being the main villain for the series, he does show a little care towards humanity as seen when his race met its demise after turned into Inves and battling each other, he would not let any other race suffer the same fate and sent Sagara to give the forbidden fruit to a rightful person to be its guardian and even killing Sid for his hunger for power. Although, he still respects Sid for his foolish action. However, he did show his villainous side by allowing Redyue to continue the invasion of the Earth. Rosyuo deems that Earth doesn't deserve to survive from the invasion. He also just wants to revive his wife, to the point if he can revive her without the forbidden fruit, he would gladly give the forbidden fruit to anyone, unless one them are worth enough to inherit the fruit.

Powers and Abilities
Though not much is known, but so far Rosyuo has shown the ability to telepathically talk to other Over Lords and even cause them pain via telepathic feedback. As of right now, it is shown that Rosyuo possess a power that is beyond anything. With the myraid of powers such as telekinesis, Rosyuo is practically the god of his realm, able to fling targets far away, move rock formations such as mountains, and disintegrate any kind equipment, such as the Genesis Driver, through brute force alone. Currently Rosyuo has shown power that is above god. Using his personal weapon, he is capable of destroying an entire group of missile that has targeted Zawane City itself.

Language
Rosyuo and the other Over Lords seemingly have their own language. This is similar to the Gurongi Language from Kamen Rider Kuuga, the Undead from Blade and Fangire from Kiva, in which an enemy faction has its own language that the Japanese do not understand.
