I honestly think their father decrowned him not simply because he believed in the killing "rumour" that Rayburn did. As a king he's got to analyse many other aspects including power balances between his wives' houses and the view of the people as to prevent things like wars or rebellions. Or at least i hope their father thought so lol
That's good point, Kem. Whatever I wonder how weak & stupid of the Emperor to handle things that way, since what he did & the reason he gave for dethronement just confirmed that illogical rumor..

What da heck! They defamed a 7-8 years old Prince for murdering the 2nd Empress?
And his father was also stupid enough to believe and decrowned him. ヽ(`Д´)ノ
Obviously, that geezer General is the mastermind.
