These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Ixion Saga DT
Ho Yay: Erec constantly checking out Kon's...ahem...equipment when they wound up in the hot springs together.
The Untwist: The rest of Incognito except for Erecpyle knew that KT was a girl.
Except the reveal was only a fantasy in her(?) head, and everyone goes on refering to her(?) as 'He', at least in the official Crunchyroll subtitles. So we either have a case of translators assuming a gender where none is refered to in the dialogue (as Japanese tends not to), or Mariandale isn't the only transexual in the show.
Word of God confirms KT as female. She hides her actual gender from the rest of her teammates… or so she thought.
