An anon asked for NSFW alphabets for the LIs so here we go, starting with our posterboy :)
Kage Alphabet (NSFW Edition)
A = Aftercare (what they’re like after sex)
Kage kind of collapses afterwards; he'll try to avoid pulling out immediately and if he's on top, he likes to wrap himself around you while he's still inside. He'll also hold on to you pretty tightly after all of that and pass out with you in his arms, hooking his leg around your lower half so you can't escape while he's asleep.
B = Body part (their favorite body part of theirs and also their partner’s)
Kage has body dysmorphia/a negative self-image, so this is tough to answer. He also has depersonalization-derealization disorder, so just looking into a mirror can be very jarring to him. In terms of where he enjoys being touched, his favorite place is his back, especially feeling MC lightly running their fingers down the little notches of his spine, or digging in to his back while he's arched over you.
His favorite spot to touch MC is the neck and clavicle, particularly with his mouth. It makes him w i l d
C = Cum (anything to do with cum, basically)
Being as obsessive as he is, he wants it inside the MC every time. If he could literally share a body with you he would.
D = Dirty secret (pretty self explanatory, a dirty secret of theirs)
As domineering and controlling as he is outside of the bedroom, he likes getting aggressively handled in bed and wants the MC to try dominating him, pinning him down, and has a touch of masochism. Only physically; verbal degradation is a no
E = Experience (how experienced are they? do they know what they’re doing?)
Kage is largely asexual outside of MC and so has no experience upon beginning the game. Just a lot of curiousity and animalistic enthusiasm
F = Favorite position (this goes without saying)
Anything where he can look you in the eyes while it's happening, or with your legs wrapped around him
G = Goofy (are they more serious in the moment? are they humorous? etc.)
He basically goes feral, a mental switch flips and he can't even speak, let alone get goofy
H = Hair (how well groomed are they? does the carpet match the drapes? etc.)
He keeps himself trimmed and is very self conscious about hygiene. He gets anxious about smelling like anything, though he loves the smell of MC.
I = Intimacy (how are they during the moment? the romantic aspect)
He can get very intense and aggressive, animalistic, is prone to biting, and has to constantly practice restraint to avoid hurting the MC via grabbing, biting, pushing, pulling etc.
J = Jack off (masturbation headcanon)
He may or may not use photos he finds on social media or takes in secret as his personal collection for this purpose. They don't even need to be particularly sexual photos
K = Kink (one or more of their kinks)
Kage would neverrr admit it, but he does have a praise kink despite being embarrassed and thrown off by compliments in other contexts. Feed his fragile ego and watch him lose his mind
Before his brain completely shuts down his mind is racing with worshipping MC, but he can't seem to get the words out.
L = Location (favorite places to do the do)
He's not adventurous in this way and wants to keep it at his place or yours, but he's not gonna say no to MC either if you instigate something elsewhere
M = Motivation (what turns them on, gets them going)
Literally any attention from MC, positive or negative. Flirting, fighting, it doesn't actually matter.
N = No (something they wouldn’t do, turn offs)
Share. No swapping, no additional people involved whatsoever.
O = Oral (preference in giving or receiving, skill, etc.)
He prefers giving it as he's insecure about how he might taste or smell. He's also on the thicker side and would feel guilty about causing MC potential discomfort
P = Pace (are they fast and rough? slow and sensual? etc.)
He tries to figure out what works best for MC, at least initially, and tries to start slow, but rough is his natural state
Q = Quickie (their opinions on quickies, how often, etc.)
He has a hard time stopping once he starts so a "quickie" is gonna turn into him wanting a marathon
R = Risk (are they game to experiment? do they take risks? etc.)
He's not one to experiment but he's very eager to please the MC, so he'll agree to nearly anything if it gets him in
S = Stamina (how many rounds can they go for? how long do they last?)
He has a surprising amount of stamina and control, unless you start laying on the praise; that finishes him off within a couple of minutes and he gets a little preoccupied with hiding his embarrassment
T = Toys (do they own toys? do they use them? on a partner or themselves?)
He doesn't own any toys and probably wouldn't know what to do with them.
U = Unfair (how much they like to tease)
He has no idea how to tease, and being teased gets him incredibly frustrated
V = Volume (how loud they are, what sounds they make, etc.)
He's not very loud outside of heavy breathing and a low breathy shudder at the end
W = Wild card (a random headcanon for the character)
I don't know how to answer this one but if anyone wants to throw something in, feel free lol
X = X-ray (let’s see what’s going on under those clothes)
He has a lot of scars from SH, has decent muscle definition though isn't overly muscular. I'd put him above average, especially in width, with a slight curve to him. He's not much of a drastic "grower" so pants made of thin materials can be a problem for him.
Y = Yearning (how high is their sex drive?)
Mainly asexual except when interacting with or thinking about MC
Z = Zzz (how quickly they fall asleep afterwards)
At first he has a very hard time falling asleep afterwards and definitely not before MC. 1. He likes watching MC sleep 2. He's anxious about MC leaving in his sleep, so even when he falls asleep he rarely stays asleep. And god help you if you try to leave shortly after things are finished
