Wait...so Othinus entrusted the world to Touma...what does that mean in the long run?
Basically, Othinus's original goal was to find someone on her level. Someone who could understand her.
But in the worlds she creates, she's bored. Everyone there are just puppets.
In order to get what she wanted, she had to go back to her original world.
But even there its not garunteed she'd find what she wanted.
Touma on the other hand could provide what she wanted.
So when faced with her final choice, because due to her fight with Touma her ability to create new worlds was comprimised, she decided that rather than possibly search her original world and not find what she was looking for, she'd go to Touma's world, who could provide her with what she wanted.
