I can accept the fact that the manga is completely different from the anime, what gets me is when both versions have very similar scenes but with a completely opposite meaning.
The context of these scenes is almost the same. There are set before Utena’s final confrontation with Akio.
In the manga, Akio reveals himself as the World’s End and tells Utena to meet her the next day so they can make a ritual that will allow her to finally meet her prince (who in this version isn’t Akio). Of course she ends up accepting because she doesn’t have any other choice (she love Akio and can’t help it) and also she still wants to see her prince.
In the anime the situation is more complicated. At this point, Utena is not only starting to figure out Akio’s true nature but also she’s starting to see that neither herself nor Anthy are exactly who she thought they were. She already knows that Anthy manipulated and hurt her but also she has accepted that she too hurt and lied to Anthy. She’s aware of her faults and wants to do something to mend her ways. In the conversation she has with Saionji and Touga before this it’s made clear that she’s not only doing this for her prince, she’s mainly doing it for Anthy. This leads to a final verbal confrontation with Touga that we’ll analyze later in this text.
