To be entirely honest, I'm not really sure how you ran into that issue.
Trinity BAKumA has its own online reader - though I will admittedly never get used to the Foolz slide style - it's up on Manga Traders (downloadable or available online) and it's also up on Batoto. I'd highly recommend that those three places - scanlation group, MT, Batoto; in that order - be your first destinations when you're looking for some particular series. Unless it's here, of course.
Is that about licensing? You're confusing me, friend.
@het, well there is a...reverse trap(male?) I suppose, and whats-'er-name is in love with the principal. Happy to drop the tag if someone prefers it that way.
The tag is fine if it's relevant. Though, isn't reverse-trap means a girl that dressed up as male? So, it's not like there'll be dudes popping out into the scene right? That's the only thing that matters to me, anyway. This is yuri reverse harem! If any dude lays one grubby filthy oily paw in it, even if God forgive him, I WON'T!!!
