I like me a good TG scenario (preferably magical but I digress), but this ain't it, assorted MangaDex commenters. Iori's a man who likes to crossdress and get all lovey-dovey (and sexy) with his hot tomoby gf; ain't nothin' truly trans about that as far as I can see.
Now, I mean, if he wanted to slip some fat padding up in that dress... well... I'd like to see that even if just for Hazuki's reaction. Go big, though. None of that B-cup BS. Gimme H-cup heaven, Iori.
