The third Otome Game no Heroine de Saikyou Survival book goes on a bit of a sidequest to eliminate a village full of orcs before looping around at the end to return to the conflict with Graves, while also setting the stage to pull the protagonist back into the Princess’ orbit. It’s perfectly fine.
Moto Ansatsusha‘s second entry meanwhile unexpectedly introduces harem elements instead of focusing on the established love triangle. Is each book going to feature her attendant and the prince being jealous over a new suiter (whom she doesn’t even realize is attracted to her)? That seems like it will get old fast. Putting that potential issue aside, the only other problem is how weirdly the remaining twin is handled. Flipping from ‘delusional idiot’ to ‘promising assassin’ so quickly makes no sense whatsoever.
