so in dto Dawn there's a theory that the reason why Ira is so off the- walls insane is because she basically started her character Arc in the series half the bomiz now in her introduction we had Ira try and rise up okaron when in reality she was just attempting to inflate her own ego and give herself a reason to feel Superior and Momo bearing witness to all of that shows to stand against her shenanigans and in an act of her own Justice for okaron she drops a tub on her head now it's very likely that
this gave Ira a mad concussion that she just left unchecked so this was the beginning of her mental spiral but not the end later there's the whole incident with the original Acro silky and due to certain circumstances Ira ends up unconscious and dead for a couple of minutes which definitely added insult to injury and possibly worsened her condition that's why she thinks Momo is a demon and why she's so hyper fixated on okaro 99% of the time
