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

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

He later punished Deemushu for disobeying his orders.

Personality
It seems that Rosyuo is sort of like an authority with the Overlord Inves. He is however trying to revive the mysterious Overlord Queen who acts like a King.

Abilities
Though not much is known, but so far Rosyuo has shown the ability to telepathically talk to other Overlords and even cause them pain.

Etymology
The origin of his name Rosyuo (ロシュオ?) might be coming from "Hakua" (はくあ?), means "Chalk" in Japanese.

Language
Rosyuo and the other Overlords seemingly has its 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. As with the Gurongi, Japanese subtitles aren't provided for Rosyuo's speech, it is unknown if they will be provided in a later release such as a TV rerun or DVD release.
