No one's posted one in a while, so I figured I'd give it a go. 3x3 Fire Emblem Edition
Loves it/Takes it: Corrin. Is it any surprise? A girl that insists on going barefoot her whole life with feet that cute is pretty much just asking for it. She knows what she likes.
Loves it/Tries to keep dignity: Lucina. Confirmed ticklish in her support with Inigo. She threatens him when he tickles her, but it's in a sort of cutesy, impossible-to-take-seriously way. She was just flustered about getting so familiar with the Shepherds' certified tickle fetishist. But I think she loves it.
Loves it/Fights it: Elise. Little explanation needed. She is confirmed to love getting in tickle fights with her siblings. She loves to be tickled and will fight back.
Loves and hates it/Takes it: Robin. The girl always in control, always in charge, ever pragmatic and tactical. Someone like her gets a thrill like none other from having that control taken away from her, and having her weakness exploited. And as has been discussed before on this board, that girl habitually hides those feet of hers. Getting tied down and having her weak, sensitive soles tortured at the whim of someone else is a dream for her, guaranteed. But it can't be denied that it's also torture for her. That just makes it better for both parties, of course.
Loves and hates it/Tries to keep dignity: Severa. Classic tsundere. She won't admit she's having fun, not only because that would involve admitting to having such a shameful and childish fetish, but it also really is just torture. It ain't easy being so tsun.
Loves and hates it/Fights it: Lissa. Perhaps not as prolific a tickle fighter as Elise, but is there any doubt that she's seen her share of tickle scrapping? She doesn't have Elise's stamina though, and where Elise is enough of a lee that she doesn't mind losing, Lissa really will try to win at all costs. She just often loses anyway.
Hates it/Takes it: Bernadetta. Poor Bernie learned a long time ago that fighting just makes the punishment longer. Just take it, laugh and beg if you must, but don't try to get away, and don't even think of lowering those feet. Poor girl.
Hates it/Tries to keep dignity: Flora (and to a lesser extend, Felicia). Both sisters are surely ticklish and can't stand to be tickled, but when working for a family that includes siblings like Corrin, Camilla, and Elise, the chance that either maid could avoid tickling was very near zero. They've learned to just take their knocks (and their turns in the stocks).
Hates it/Fights it: Ingrid. She hates how ticklish she is. It's beneath her dignity as a knight, and if you tickle her she will try to destroy you. If you plan to tickle her, you'd better be willing to go all in, because once you start, your only chance is to tickle her into submission and wear her out until she's too weak to fight back.
