I am reminded of this post
here. In all three of Ikuhara's major productions, the main characters are freed from flawed and broken systems, even if the flawed and broken systems still remain regardless. In Utena Akio is made out to be a fool; a stubborn prince who refuses to leave his coffin and is trapped there by his own selfishness, power complex, and desire to control others. Meanwhile, the students, especially Utena and Anthy, break out of the system. In Penguindrum, Shouma and Kanba give up their humanity to change fate for Himari's sake. Sanetoshi swears he'll be back the next time the train comes back, but Momoka mocks him and walks away. He's not made to look a fool as much as Akio is, but instead he's defanged. Himari will live a safe and happy life, free from the punishment of fate. Ringo is no longer bound by her desire to make Momoka live on through fulfilling the destiny diary, and she can also live a peaceful life. Both have become friends with one another. The system of fate and punishment remains, but it is powerless when the realization is made that fate can be changed.
In Yurikuma, it's a bit less sweet of an ending. Ginko and Kureha escape the Invisible Storm by departing from both worlds to live happily elsewhere, free and safe. However, the Invisible Storm still remains, with its ferocity and zeal fully intact. But it is also shown that Ginko and Kureha relinquishing their existence within that reality had an impact, however small. During the Exclusion Ceremony or whatever it's called, a spotlight is shown on one girl in the crowd, who cannot bring herself to vote. She walks right out of there to the Door of Friendship, where a lonely and abandoned Robo-Konomi is sobbing. She picks her up and embraces her. You can see this as the potential for the vicious cycle of the system of the Invisible Storm to continue, but obviously the girl is aware of that. She walked out of the system for that reason, after all! So I am choosing to see that even if the impact is small, the potential to dismantle the system still exists, even if it's through one person at a time. She'll inevitably be the next "evil" target, but maybe they'll both end up where Ginko and Kureha are in the end. Who knows?
