I can kind of understand this, I don't agree but I understand where you're coming from. I'd say she classifies as femdom only if we really stretch the definition to "woman who doesn't immediately roll over and get plowed with the MC whips out his dick." She's assertive but not dominant, confident but not controlling. She knows what she wants and, once she gets over the whole age gap thing, isn't afraid to go for it.
Nancy had less femdom vibes early in the game, she went from loving housewive and mother, to matriarch in full control of everything, including sex. In contrast, Carla was very insecure until the end, like a teenager in love.
Also when the MC was nearly dead in Eternum, he openly said he is nothing without his girls, while in OIALT they were more like a support for him not to fall to the dark side, not the ones giving him his powers.
There is femdom as in
she is in full control and he is a subordinate, and femdom as in
she pegs him and burns his balls with cigarettes and so, I said "borderline femdom" because of course there is more room for femdom, but it's already a sharp contrast with OIALT where he was much more dominant and in control of situations, only Aiko was more dominant but the others were more submissive.
And she's a mature woman who uses her experience and wisdom to help guide things in the right direction, but I think that's largely a framing device to avoid the home stretch of the game involving either A) a bunch of awkward, forced dialogue about how all the girls are totally into being a harem, or B) having certain girls just totally unaware it's going on until the epilogue like in OIALT.
There's no need for forced dialogue, he is a superhero, the Chosen One, the G.O.A.T. , a young god in the making. Women are attracted to much less than that even IRL and when they are attracted to such individuals they don't care about anything else. They might not be superhappy about the harem, catfights and jealousy could be frequent but they would put up with it in exchange for being with the man of the age.
This on the other hand... huh? Appreciating what you have and making sure your partner is comfortable is femdom now, apparently?
The way it's portrayed in the last updates is closer to femdom than to the opposite, yes. And it's in clear contrast with OIALT, where none of this ever happened.
I think most people would be extremely thankful to have one of these girls interested in them, let alone eight. OIALT MC did the same thing, though admittedly usually while ogling some T&A. But associating Orion's relationships with Annie and Nova to femdom is laughable.
Thinking "
I'm a lucky bastard" once in a while it's alright, but acting and talking like he should be thankful for having any kind of contact with them, every single minute, IS much closer to femdom than to the opposite. HE is the hero, he is on the way to be the next Founder, they are attracted to him because of that. In OIALT he wasn't an insecure pussy full of incel vibes, but in Eternum it looks like he is more insecure by the day, when he should be less so because he is being increasingly successful.
Tsundere isn't a matter of status or personal belief, it's an attitude. It's loudly and aggressively insisting that they totally don't care about you and have no interest in you while clearly caring and having interest. Caly may not be completely in tsundere territory yet, depending on preference, but she's getting there. Give it an update or two and I guarantee she'll fit the definition to a T.
She will blow the MC in 0.9, she already did a magical no contact handjob, so next step is a blowjob.
