Listen I think Natsu is feral as fuck like only partly cause he was raised by a dragon but also cause my dude is just fucking like that like even the other slayers are not that feral. Natsu got raised by a dragon who was doing dragon things and my guy said alright bet I’m a dragon now and went full on all fours bitting people growling on the playground feral
♡ as annoying as this is to her, lucy always falls asleep when she reads. it takes forever for her to get through a book! it's just so soothing, especially if the story is compelling and lulls her in... bonus points if she's on a train or in a car; the rocking motion will have her out like a light.
♡ levy has no trouble getting through books because it gets her excited, not tired. she doesn't let lucy forget this. she does, however, stay up until ungodly hours of the night to finish a story. gajeel, jet, droy, and lily have found her passed out over a book (or twenty) multiple times. I think she's always buzzing with energy or curiosity, so one of the only ways for levy to settle in is if gajeel literally lies on top of her like a weighted blanket.
♡ speaking of, gajeel is very neutral about naps. he doesn't actively seek them out, mostly because he's one of the few members of the guild who has a relatively normal sleep schedule. he is, however, soft as hell. levy and lily always nap on him. wendy will nap on him. juvia will nap on him. gajeel looks scary asf if he glares, so no one will bother whoever's sleeping by his side. he is also actually very squishy if he relaxes his muscles. 10/10 pillow.
♡ cana naps like nobody's business. she goes out at night, stays up late drinking or partying, and crashes at 3am in gray or loke's bed. there is no "schedule" to sleeping so she will sleep whenever and wherever. cana has the uncanny ability to fall asleep anywhere. slumped over a table in a guild hall while natsu and gray throw chairs at each other? out like a light. lying on a freezing cold bench while her and lucy wait for a train? snoring away. (lucy pulls cana's head into her lap.) cana rarely falls asleep in an actual bed, though. if she does, it's because she's dead tired, and she's been incentivized by cuddles.
♡ natsu looooves a good nap. him and happy cat nap all the time. this might actually be the only consistent thing in their schedules: nap. the entire guild knows, courtesy of mirajane, to stfu for a bit when 1 o'clock hits. they don't actually need to, because natsu could sleep through a storm, but it's the thought that counts. natsu is also really warm and cuddly, which means that he's the perfect napping buddy. being buried in his warm arms, snug as a bug with happy between you... truly the dream.
♡ gray hates naps. hates them!! all because he wakes up the way you wake up from an after-school nap: sweaty, dizzy, disoriented, in a different dimension, with an overwhelming sense of dread. he reveals this one night when he and lucy are plastered at a bar, and that he's slightly jealous of natsu. lucy resolves to fix this, and when they're both blackout drunk she drags him into bed with her. not quite a nap, but hey, gray woke up feeling nice.
♡ sting might be the only character in the fairy tail universe that goes to bed at 10pm. his sleep schedule is on point, so he doesn't really nap unless he's exhausted from running sabertooth's infirmary. he will snuggle up in a square of sunlight with lector and snooze away.
♡ what is a nap? minerva doesn't nap. she doesn't need to rest during the day, she has things to do, what are you talking about- oh. oh. I think sabertooth has a very luxurious library, and minerva knocks out on one of the plush purple couches. more often than not, frosch will worm their way into her arms. the only people who dare to mention her naps are yukino (who minerva has a soft spot for) and sting (who has no sense of self-preservation).
