Teasing and denial
She really leans into it when it comes to asking for encores and goes "sha nai na" a bit before "giving in" during any karaoke stream. She often brings things up about her body weather it's her breasts or feet knowing and often denies playing into a bit more or does that and then elaborates or does more. What's more is that when she was asked why she doesn't swear/ lower her filter during the last Q&ASMR, she responded by sensually whispering "you'd hear the F-word out of my dirty little mouth every 5 seconds"
Attention and Praise
Like being told every song she sang was a favorite during her song learning stream and responding with "that's the right answer" or something like that. I wouldn't say "harem" specifically just yet but just likes the idea of her being fawned over and plenty of guys doing it for her is definitely a plus. Faun barely pampered her and she wanted to sit on and shoved her his cabbage in his mouth before he could consent. That and last two streams (at least) we were told to come and praise her every stream. That and "do it for IRyS"
Loli
Can't stop uohing over Nobeta and really really wants to see her in all of the costumes. She also said she wanted to be a loli instead during the last Holucure stream and some other times. On to of that, in her last Geoguessr stream I think she said something about wanting to revert to her younger kid self with her current brain. That of course would better serve the other things too. So does she want a loli or want to be a loli? Yes
Incest/Brocon/Siscon
She likes eromanga sensei minus the fact that they aren't blood related. She immediately made toad/toadette "not blood related" jokes right off the bat last Mario party collab. IRyK kept mentioning his sister constantly
Dom
I don't think there's much to this aside from light stuff. Like her idle threats when someone make a comment about her breasts or jokingly annoys her. She did shove her foot in her mom's face and forced her to smell it (to prove it wasn't smelly when she was a kid) for what it's worth
Yandere/Loyalty
She has tiny amounts of yandere-ish tendencies. Like the whole GTA V Micheal NTR plot that spawned a whole bunch of cockbell jokes in the thread (which I might've had a hand in starting). She was really clingy and and was of constantly suspicious of his wife at every turn expecting the NTR eventually to happen. (The NTR did eventually happen.) She was probably just projecting a bit of herself onto Micheal as opposed to her liking the whole yandere angle. She gives a 70% luck bost to everyone who has only her as an oshi. The more oshis you have the less luck you receive and if she draws you a profile picture you have to use it for at least a month (outdated) or never take it off (up to date). That and the occasional puppy-dog eyes/sad bit when she doesn't get validated
Size
She often gets wowed by proportionally large things like (idk uh) the trees in the last Geoguessr stream (off the top of my head) and has a tendency to to call smaller things "cute" like on her last Q&ASMR I guess. There are more SizeQueenRyS moments but I can't remember them right now
Non-Con
During IRyS' futon "stream before stream" she did veer off in that direction is all I really need to say but I'll add. Her futon being used when she was gone, felt it's warmth, sniffed it a bunch, talked about feeling a stick on her face and not bothering to wake up. She also got voyeured and almost got fondled in her sleep. I remember some justifications being "It's totally fine. It's not like this girl is taken, right?" Everyone could see how rapey it was. Especially because the schtick went on for almost an hour
NTR
Carrying on from the non-con, there were more justifications like, "Oh, she's married? It's okay. I'm just trying to wake her up." She did have a whole fantasy where she (reminiscent of her GTA V playthrough) exaggerated her mom's relationship with Clive and and turned it into an NTR fic. She also when around and married a ton of people in-game as a kid in some rpgs for items or whatever and got slapped for being a two-timer or something but seems look upon that memory fondly. So she might slightly be into NTR if she's getting chosen. If so it's most likely just that part and not everything else it comes with, which loops back into Attention and Praise. Especially her not liking the NTR in White Album 2 which she talked about with Reine on that one twitter space
Swallowing(?)
Up to you to decided how legitimate this is. When she started eating Faun's cabbage and as asked to spit it out she want to swallow it instead. That and I think she randomly brought up that she hated people just spitting on the side of the road disgusting. It's not much but it's more than enough to extrapolate with
There's like at least 10 legitimate things but that's all I got. Hope that helped
