TFW your icon vanishes from the story without explanation.
Magane’s plans were resolved completely in the previous episodes. I guess its fine to be a little disappointed she didn’t get a nod and a wink in the final episode, but she didn’t strictly need one.
In episode 20, Magane is at an airport- An airport is a clear announcement that she plans to leave the country. Furthermore, her speech with Sota in 18 tells us everything we need to know about her world views and plans for the future.
Magane wouldn’t be able to live with herself going back into the story she came from. Her creator is dead- (And she probably didn’t kill him!) - her story won’t be the same going forward, if it even does.
Magane’s core philosophy simply involves enjoying passion, struggle, and stimulation in life. She genuinely, innocently loves when people try their best, watching people strive for something. And there is no better place for her to do that than in the creator’s world with its information depth, billions of unique people. In a story, she is so limited. In reality, Magane is freed from her role, and has so many options. Her goal ever since things settled down a bit during the production of the Elimination Chamber Festival has been simply to experience the world; to see new things. If you ask me, she is even tired of being a villain.
Simply put, Magane’s been behind “True Incarnation” since before the initial fighting even stopped. And with Meteora- episode 22 shows us that nothing special is even required to do this. All that needs to be done is to stay- and their powers will fade away, leaving them as normal humans.
Magane doesn’t need her powers for what she wants to do. They are less important than her philosophy.
I was satisfied enough with her role in 20, and I think it pretty comprehensively tied up her arc. She got to involve herself critically in one of the most influential and important schemes on the planet, and get away scot free. Her role as a strengthening influence on Sota, foil to Meteora, and position as a neutral chaos party was fulfilled. She grew as a person, expanded as a character, and adapted her worldview, changing how she acts subtly.
And now she is free to travel the world on her own as some kind of wandering trickster god.
