Let’s start with the easier ones, first Eternity Larva. Easier? I have poor judgement. She’s a god who chose to hide away as a fairy to provide another fight against Okina a completely normal fairy with absolutely nothing else going on. She’s weirdly relaxed for a fairy which has no reason whatsoever, even if she usually acts as playful as the others. She’s also way more knowledgeable than the usual fairy, can’t tell why. Probably one of the more capable ones who would understand and be able to handle being a wife and mother. Only problem you’d have is her current form nature as a fairy with a summer focus kind of becomes a shut in during the winter.
Daiyousei! An actual easy one. She’s your typical fairy for the most part, a simpleminded and constantly joyful prankster. She has a little more to her though, as she has shown concern for Cirno when playing together. Dai would be a little unprepared for things like marriage and motherhood, but she could handle it. Her care would shine through.
Lily White is some of the same as Daiyousei, but with an added love of spring and heralding of spring. That might help a bit with the motherhood bit, not sure. Spring is the season of life and birth after all. Also contrary to what people think, she’s not a shut in outside of spring. Spring is just the only time she does the big yell. She also, weirdly for a fairy, actually doesn’t have the desire for tricks or pranks. She’s just happy to be around and is even on good terms with most humans (shrine maidens who want to shoot her not included) so it’d be easier at least to get involved with her.
Oddballs are starting here, Cirno. She’s the most defined of the fairies and quite a full character. She’s dumb, arrogant, loves pranks, thinks she’s the absolute best, and cute. Ice is not a natural element for a fairy notably, as fairies are defined by life in nature while ice is notably often considered a lack of life in nature. Still, these oddities make her strong and kind of nice to be around. She would act as a hero merely because she believes she’s strong enough to be one. That is to say, she’d be a scatterbrained wife who really would be hard to keep calm but she would be very passionate. Probably would fight people (and lose) to argue you’re the best husband because the strongest would obviously get with the best. Motherhood would be mostly her teaching the children how to act similar to her, which means you’re probably doing most of the parenting. She would at least care a lot about her children.
Clownpiece! She’s weird in a completely different way. Turns out there’s a one in a million chance of a hell fairy coming into existence. Being born in such a strong area, she’s far stronger than a standard fairy and slightly more intelligent still not at Eternity Larva’s levels though, turns out being a god means something. She’s got odd tastes formed by being around Hecatia and living in hell for a while. Though her personality is much like other fairies, she does have quite a bit of thought put into her actions. Unless it involves hell, in which case she sets the Hakurei Shrine on fire again because hell is rad. Anyways she likes chaos but is also a fairly intelligent fairy, so for the most part she’d be an interesting wife who might want to see what you look like when you go mad. As a mother? Your children are all going to be wearing tacky Welcome Hell brand shirts.
Three fairies are going to be in nonsense order because I don’t know how to sort. Star Sapphire is scary. She’s got the standard fairy nature, but with tons of common sense and a horrifyingly scheming mind. She is the first to run and last to arrive at a scene. Honestly, even if she is a weak fairy, she’s going to be controlling in the relationship. A brat to the end. She definitely knows about relationships and motherhood and would tease you constantly. She also likes stuff people might find strange. As a mother, she’ll probably be fine but she will use it to tease you and get the kids to tease you too.
Luna Child is a gamble. She greatly enjoys human stuff, including reading human works. Loves coffee too. While Luna keeps up the fairy mindset, she’s almost overridden it with her enjoyment of playing human. Still will partake in pranks, but is far clumsier when it comes to such things. Whether she knows about romance is questionable, but she definitely doesn’t know anything further. She will be woefully unprepared but try her best to be a proper mother and wife (also fun fact, since Luna can erase sound she’d probably erase her own moans out of embarrassment).
Sunny is well, Sunny. She’s your standard fairy. It’s weird to say, but she’s the least predictable. She’s a leader, but she’s not really got some specialization into non-fairy attitudes like the others. Instead she just does the typical of loving pranks and messing with refracting light. Cheery and lighthearted. Never brought down by anything. It’d be hard to ever be sad with her as a wife. As a mother, she’d just power through with her normal attitude.
For sake of special mention, Lily Black isn’t considered a separate character by ZUN, but if you were to consider her one she’s basically just a caretaker for Lily White more often than not. Essentially already acting like a mother or older sister. And no, I will not go over every single type of standard fairy because that’d be a mess and the reality is half the types of mob fairy are just normal fairies cosplaying for fun. Just take the Daiyousei statement and replace the caring nature with an interest in whatever part of nature that fairy has control over.
