The new musou game was underwhelming and barely even utilized her, but I find it really funny how it just made her the actual power behind the throne while every decision that Rauru made on his own accord was bad. Literally nothing would have gone wrong if he just listened to her and every good decision he made was because Mineru suggested it, the game makes you question why he's even in charge. Like despite her barely even being in it it was kind of just confirmation that she's actually best girl.
