The heavy surrealism in RGU used to frustrate me as a new viewer, but now, I think it's such an integral piece of Ikuhara's storytelling. Because to me, the absurdities of Ohtori Academy perfectly capture how it feels to live under an abuser.
We as outside observers naturally question why there's a baseball game happening during the Student Council meeting, or how thirty cars can magically spring up in the middle of the dueling arena. And yet, the characters hardly bat an eye. Utena initially struggles to make sense of the duelists, the Rose Bride, and the Castle Said to Hold Eternity, but the more she becomes absorbed in this system, the more normalized it becomes.
We viewers fall for this, too! Show someone almost any Utena scene out of context, and they're going to have questions. Did that guy drive his car through a second-story window? Why is this boy boxing with a kangaroo?? Where the hell did all those swords come from???
"Yeah, don't think too hard about the logic. That's just how things are at Ohtori, you know?"
It's debatable to what extent the characters can perceive the visual symbolism that Ikuhara presents to us. Nevertheless, Ohtori remains a very weird place. But abusers possess the sinister power of normalizing behavior that any outsider would find absurd and unacceptable. They can — quite literally, in Akio's case — project their own version of reality onto their victims.
When Anthy gives Akio her glasses at the end of episode 39, she's rejecting the version of reality that he's convinced her to believe. Through Utena's sacrifice, she can finally see her circumstances for what they truly are.
The exit to Ohtori was always there for Anthy, but like so many real life victims of abuse, sometimes the logistics of leaving aren't what's keeping you trapped. An abuser can make themselves your whole world, and sometimes the greatest challenge can be realizing just how small, confining, and batshit crazy their rules really are.
Abandoning the life an abuser has made for you can feel impossible from the inside. But then you catch a glimpse of something beyond, something that makes you look around and ask, "How did I think any of this was even remotely normal?" And suddenly, leaving starts to feel like the most natural thing in the world.
