Big Brother CG and Regressor (Flip) Sephiroth HCs!
(oh gosh, my second headcanons post... hopefully this is decent!)
He's a very matter-of-fact CG. You tell him you regress, he gets it surprisingly quick, with a few questions. (He neglects to initially tell you that he also regresses because he didn't want to admit that out loud. That, and he mostly regresses solo.) He agrees to watch you when he's free or available enough.
Very lowkey. His caregiving style is very much so akin to parallel play. He keeps an eye on you while you do stuff while he does stuff also...
...but he's happy to give you more attention if you want it. You just have to ask, or, he'll watch for your cues. His keen perception helps him a lot, even if he doesn't always know exactly what you want.
However, this also means he'll notice when you seem sleepy or hungry or otherwise in need of something. This doesn't bode well for any stubborn regressors who'd rather deny that they need anything at all. Good for easily distracted regressors who give unconscious cues but don't realize them on their own.
Strong enough to carry you, and honestly? He's likely to, as long as you're alright for it. He'll scoop you up and put you down like it's nothing.
He's content to hold you in his arms and rock you.
He'll let you play with his hair, as long as you don't pull it. He'll even let you braid it or put it up as long as you're gentle!
Being firm comes naturally to him, and he can make himself clear about what he's telling you to do with ease.
He does his best to be gentle with you in your vulnerable state, even when he has to be firm. He doesn't want to hurt you, even on accident.
I know this trope is silly but let's face it, Sephiroth's a high-ranking SOLDIER, of course he has a ton of paperwork to do. He'll give you your own "paperwork," just coloring sheets or worksheets. It's not much, but he'll give you a multicolored pen to do them with.
He probably stashes some subtle gear-that-isn't-outright-gear in his desk for you and himself.
He'd hesitate to admit it, but he does enjoy caring for you. You matter to him... quite a lot, in fact. He likes seeing you so carefree and expressive.
Likes small spaces, curling up into a ball and folding up on himself, almost catlike in that he'll fit himself into any space.
Doesn't like the subject of anything related to SOLDIER work or training (except maybe when he's regressed a lot older - I could see him teen regressing) because he's dealt with it too much to begin with. He doesn't want to be a hero. He just wants to be a normal someone.
Thus, his pretend play is very grounded if he pretends at all. He would like games like playing house.
A good mother figure would absolutely break him. A good father figure would be strange to him, but not unwelcome. He's more fixated on the concept of maternal affection and he gravitates toward it more, but he would die for having a happy family and people to care for him.
He takes well to other familial figures, too. He prefers them to be in an older sort of role. Siblings, aunts or uncles, grandparents... literally anyone to take care of him.
He tends to regress very small (at least, to him) and tends to not speak much.
Can be independent and capable even when regressed, but is not one to deny help from someone he trusts as long as the coast is clear for his regression. It takes him time to get comfortable regressing around someone, and he tends to deny help initially, even it he's frustrated. His walls take a long time to break down. Once he trusts you, though? Oh, there are no such things as walls and barriers.
Mix of voluntary and involuntary regression.
Masks well, but quietly melts down as soon as he's alone after a long period of masking. It's unlikely he'll let many people, if anyone at all, in unless he's desperate at a time like this.
Expects to be punished at every turn. It's best to not punish him at all.
If he lets you in on this, you have to keep it a secret. Don't betray his trust. Please.
Genuine and specific praise will make him very happy.
He just wants to be good. He just wants to be normal.
All in all, he's a secretive, even slightly ashamed regressor, but once there's trust, you're never going back.
Get this dude a paci, stat.
With that, some soft toys, too. Cuddly things.
If you ever put his things away for him to make sure they're not out in the open, he will consider you an absolute godsend. He's less diligent at times when regressing, but at other times, hyperaware and nervous.
He will take any affection you give him. Hell knows he's been deprived of it all. If he's regressed older, he might resist it. When regressed younger, he will never resist it.
He knows it's probably hard but if you can rock him, he will be at peace.
He isn't quick to admit it, but you can simply tell that he loves every moment of your care.
