Oi, just ‘cuz yer’ a space princess doesn’t mean you get to practice cryosleep incest. It’s of vital importance that the nobility of Jurai establish firm moral behavior so as to be an example to inspire the common people. She will marry a genetically fit man to whom she has no blood relation going back at least twenty generations if I have any say in the matter.
As for the prototype bland harem protagonist, not only is he a powerful, plot-armored MacGuffin (valuable by itself), but as the super-protoype for the other K-series Harem Protagonists, control over his narrative would allow Ryoko to indirectly control all the other harem anime protagonists in an amount according to how little personality they have, allowing her to enter other series entirely and rule them as sovereign and/or drunkard.
I don’t see how you could have an objection to this.
Mihoshi would of course ruin this plan for interdimensional conquest, and thus must be kept far away from it.
