Personally, I think it's weird that they didn't even put an Ano route in. Considering how late Yuna's romance arc occurs in the story, it wouldn't even have required much in the way of rewriting. It's especially weird how they didn't add anything in the Final Chorus edition- I'd assumed that they ran out of time or budget in the original and rushed the third act, but the issues still persist in the flashy re-release. I don't mind Hina, but her entire character just made me go- That's it? There was no real change or development, no deeper-seated personality traits, and none of the realism and charm that every single other character in the cast had. Hina is cute, but her overall personality's blander than your average isekai protagonist, and like the poster above mentioned, this comes off as even more glaring because of how well-written the rest of the cast was. An average series could've swung it, but not something as great as Kindred Spirits.
From a purely plot-oriented perspective, it also makes so much more sense to have Yuna end up with Ano- her mysterious candy is the trigger for the entire plot; she's always been able to detect ghosts and is somewhat afraid of them, making her a great foil to Sachi and Megumui's desire to be seen; she's got connections all over school and is a natural yuri shipper, which contrasts brilliantly with Yuna's relative isolation and plot-designated role as a Cupid; she expresses some fascinating views about yuri as 'fiction and fantasy' being a lot more alluring than the reality of lesbian relationships, which would've opened up space for the VN to examine its own identity and the nature of the genre itself; she's got deep-seated issues with anxiety and affection, operating as a mirror to Yuna's own dark past, whilst also working as a foil to her confidence and calmness; her position as Yuna's ditzy best friend, classmate and emotional support has a lot more potential than Hina's weird pseudo little-sister schtick; and overall, she's just one of the most likeable characters in the cast. The fact that they did absolutely nothing with her in any regard at all is genuinely baffling, especially since the promos and title screens position her as a character who's ostensibly just as important to the plot as Hina, despite getting minuscule amounts of screentime compared to literally everyone else in the cast. The fact that both Hina and Ano were so oddly-written and underutilized is my sole criticism against what is otherwise one of the best yuri stories I've encountered in any medium. At some point, the flaws go beyond a subjective preference for AnoYuna over YunaHina and into legitimate confusion at the fact that the former is nonexistent even as a route, while the latter is so badly-written despite occupying the center of canon.
