Which littles does she care for?: really anybody!! She's very sociable and gets along with most other regressors. Though mainly ikeda or mion , plus very rarely hirose.
What nicknames do littles use on her?: She doesn't have any specific titles, she's fine with any nicknames of her name or (big) sister!! I don't think she'd mind parental titles like "mama" that much and even find it cute, even if she has more of an older sister role ^^
As mentioned before, i headcanon denden as a permaregressor (8-12), but she's still very capable and loves taking care of other regressors! She doesn't even need to try that hard, playing with them just comes naturally to her.
The number one activity she does with them is drawing. It's quite calming for her and she loves seeing what other littles come up with!! Though if they're too small for that she'll also happily play pretend or just let them cuddle up to her.
She struggles a bit with knowing how to deal with littles when they have a tantrum. But she naturally has a calming vibe to her, so usually she just tries to talk with them softly and wait for them to calm down and figure out what they need.
She is absolutely AMAZING to hug and cuddle with. And denden enjoys physical touch a lot!! No matter how big or small the other is, she'll happily let them cuddle up to her and keep them in her arms :3
I think she's especially good with dealing with regressors who regress around 3-10. She has a harder time with baby regressors, but with a little help from another CG (usually hirose..) shes able to do it!!
Tends to get overexcited to the point she gets a littlleee too loud and struggles with regulating her voice, but will be very apologetic if it overwhelms the little :'3 she tries her best to stay her energetic self while also keeping her voice gentle..
She's very set on the fact nobody should feel ashamed to regress and also supporting the littles boundaries. If they want something she'll do her best to get or do it , and even if she struggles with picking up on social cues, when they tell her NOT to do something she takes it very seriously and will also make it clear to other people not to do it.
Is one of the only people hirose will regress around. She's surprised the first time he does, but doesn't mind and really just acts like her usual self, which is comforting to him. She enjoys being able to take care of him too and helping in getting him a break for once.
Both her and isoda take care of hirose togheter, or hirose and her take care of isoda togheter. She sometimes needs a little guidance from either of them on what to do, but she's a very nice person to have around!!
— ❄️ Afterword
I always try to keep my headcanons as general as possible so people can also kind of imagine themselves as the little being cared for, but i did wanna get into hirose and dendens dynamic a little bit... i try my best.. i hope you enjoyed <3
