Onimai: I'm Your Sister Now!

I can't believe we're finally at the point where this exists - an anime that was specifically designed to be an indulgent, fun experience for transfemmes. I can't imagine it being for any other audience, because it's just about the experience of Getting To Be A Girl in a way that feels like a colorful, exaggerated version of all of the good parts of being transgender, the new experiences and the social awakening and the second puberty, and the OP goes "trans trans trans" and it's just so nice!!!
