Because I'd rather have someone that's actually alive and knows how to smile? If Vai'klis is so damn amazing then how about you try to enlighten me?
Change my mind
Well, I'll make a confession: Before this latest update, I believed she was pretty overrated. I felt like people loved her just because she was the gentlest girl in Hornsperia- an oasis in a desert kinda deal, thinking that sandy water's the most refreshing beverage in existence just because you were on the verge of dehydration.
Now however, she's shot up in the rankings a lot for me, which I generally measure (as in, I don't have an Excel sheet or anything for it) by H-scenes, the relationship, the story arc concurrent to the relationship, lore, and the girl themselves, though not necessarily in that particular order of importance.
As for Vai'klis, you're kindred spirits in a lot of ways- you both can't remember your past. There's no other girl who can truly relate to your condition other than her, that's a wholly and solely unique aspect for the MC in the relationship bracket.
Next up, you take issue that she's "cold", physically. I admit I can't really understand the issue here, as we're not actually touching her, and the MC doesn't find it uncomfortable to the point of pain. In fact, it plays into the relationship- Vai'klis has a lot of skinship in her route because your touch is more than just physical, your very soul's warmth touches hers. I like thinking about her curled up around the MC nestled in her chest, keeping hostile spirits and ghosts from harming you while you keep her warm and chase away her bad dreams with your presence alone.
She may have a hard time smiling, but when you play her route it's apparent to me that you make her happy. She's not the Queen, even if she aint smiling it's not because she's some ice-cold bitch who'll murk you for lying about playing a children's game with some giant childish maids, it's because she has a hard time due to the nature of her undeath- but there's no doubt the MC will be her island to cling to among a dark sea, her sunlight in pitch blackness. The nature of your closeness goes beyond physical, it feels like with time your very souls will connect, and for me at least, there's no greater intimacy than that.
Now tbh, Vai'klis
isn't my favorite. She's shot up in my rankings, but there are still a lot of girls I put above her- but it's also a bit unfair, her route is still one of the shortest, beating out only Makla (remember her?) and Kive at this point, so we may need a Vai'klis fanatic to weigh in to better explain her appeal than what I can, but that's what appeals to me about her- tbh there's also the matter of the MC's backstory being explored more on her route than any other so far, but this post is way too long already, haha.
