It seems like many people are not fully considering this current storyline of the show or are dismissing ideas without giving them much thought. This story arc isn't just about who is right or wrong; it presents the idea that a character's decision is based on being pragmatic, not just for one person, but for everyone. At this point in the story, no other characters have come up with a solution that wouldn't cause regret in the long run. However, this particular character realizes that by eliminating any potential regret, they can achieve their goals without creating problems. Despite understanding this, the character still hates the conclusion and only accepts it because there seems to be no other viable solution.
@wanna-sleep-all-day Even when she reveals her true intentions, how she expresses herself still appears ambiguous. It seems like she might be withholding information or not being completely honest. Whether she is an unreliable narrator or is intentionally hiding details, we still don't understand why she has changed her mind about wanting to protect Yuga's future. We understand what motivates it to go on this path but not the reasoning of why Yuga's future seems to be the ideal. That's why it's important to understand how this episode is presented and framed. And I think that's something we will know in future episodes.
Look at episode 114, when she mentions other alternatives when talking with Kuyamuya:
Also, in this line of dialogue when she is talking with Yuudias, she expresses the pain of going to this crusade:
There is also this scene because people seem to imply here, that she is only thinking about Yuga when this is the contrary, she is thinking about the sacrifice she is making to herself to save both Velgarian and maintain Yuga's future:
This also implies why she considers erasing memories of other people as an option because she doesn't want any of them to suffer.
(Note: After she reveals to Yuudias that the wall of shirts is going to destroy the Dark Matter space, it is implied that she cares about Yuudias's baggage.)
That's why I think there is more to the Yuamu plan than benefiting Yuga alone. The goal is to save as many people as possible by eradicating her individuality and memories and adopting a fully rational mindset. This is the reason why I believe, she chose Yuga Future as the sole option because it is one where there is still hope. She would be willing to give up relationships with the people she loves to ensure their happiness.
