To be an attention whore.
If that is enma, we know that enma is literally a tranny from singapore. Or maybe that person is actually the producer? In any case that kind of person inevitably, unavoidably has an insecurity that reaches down to the deepest root of their being about themselves - and managing a bunch of cute girls living and being what you wish to ideally be, probably does something to your head. Like it's so close yet so far, so near to you but yet, having a close look at them only highlights how impossibly not-that that you really are, how you will never actually be that, not in this lifetime of plane of existence.
So enter Omega, the self insert way to try to be one of them but also, not quite actually be expected to be a cute girl if it ever has an opportunity to speak on stream. If OA pays any attention at all to Western vtubing outside holoEN he'd know how (not) well Artemis went over, and was not going to just walk into that himself so made the char androgynous. Troon insecurity is in fact MEMEME on a giant pail full of steroids, the need to seek reaffirmation / validation of themselves, to forcefully carve out a mandatory position of respect and power (ironically a very masculine trait/drive). I don't at all hate trannies for existing, biology/brain development just alters people sometimes and that you literally cannot choose to rewire your brain so there is no use crucifying people for having different neural connections. However, as fundamental as biology is, it is also fundamental psychology that basically no adult likes being forced or told what to do or how to think - and trannies sometimes make it their goal to proselytize, forcefully bend everyone's minds which only will push a lot of people further away.
