まこと か(?)/お汁!!! will be
Is it true!?/ O-shiru!
As Owari01 said, O-shiru was a proper noun in this case.
I bet that O-shiru is his (King's servant's) name.
"O(honorific)"+"general noun" used to composes Japanese name.
For example, "O"+"tsuru(crane)" is female's name and,
"O"+"kuma(bear)" is male's name. Although both of them are outdated.
And as saladesu said, O-shiru was very ridiculous for person's name.
Shiru(= soup or juice) is unsuitable word for person's name.
I think the author selected "shiru" for effect, in other word, as a gag.
*Blue jokes warning*

Sometimes, "shiru" is an allusion of pre-ejaculate, sperm and love juice.
The manga you are translating is dirty gag manga (I guess that's Man☆Gatarou/漫☆画太郎’s one), isn't it?
King's name "Musukondoria" is a portmanteau of mitochondria and musuko(=息子/son, allusion of penis).
Thanks
