Ofelia Danisoya.
This was the sixth Prince of the Kingdom of Dennisiowa whom Annan had met on the treasure ship "Silver."
Though merely the "sixth Prince," which sounds a bit far back in the line of succession... even before the death of Philip and the concession of the Eldest Princess, the heirs to the Kingdom of Noah numbered only half that.
However, in the United Kingdom, Ofelia could still be considered among those fairly high in the line of succession.
—For this generation's Dennisiowa heirs, there are over twenty direct descendants of the royal family, not counting any illegitimate children.
The main reason for this is that the spouses of the King of Dennisiowa far outnumber those of the King of Noah.
There is also the fact that the degenerate has not yet come to the United Kingdom to cause trouble. Should the degenerate be stationed here long term... It would probably only take about half a year for the Dennisiowa family's heirs to decrease by a single digit.
