Gender locked race?

Or it could be that the males remain in the village up until their society notices they aren't growing any bigger as opposed to the females.

And the logical response to that would be.... kicking them out into the wild...? "smol boi smoll, get out of village, go live in forest now". I feel that those two concepts are counter to each other, personally at least lol.

However if the males become hyper aggressive and capable long-term survival fighters then kicking them out would be fairly logical, just please come back for mating season bois.

Aggressiveness, survival, fighting, these tend to line up with a masculine appearance (although I think it'll be close to the SE concept art and not like.. BEASTMODE "can't tell if you're a viera" lol).

Especially if you consider the trope that superior fighting in males, in media/games, = extra masculine traits and fighting in females = extra feminine traits. Our females who are fighters tend to not show masculinity and appear sexy and lithe, except when done for the exception itself (like Zarya in Overwatch). Just playing the odds of gambling the descriptions that should befall someone that's kicked out and has to survive the wilds with little civilization, who is male, would be one that is at least moderately masculine.

Add on top all the other things we know like Yoshi-P's feelings on male Viera being cute.. I'm guessing males are not "cute small things forced into exile".
