Chapter 11: Main Concerns
The nonchalance and laziness caused LiGTHs to relax and forget their motive as the princess learns the truths of the world hidden beneath the light. In Mamuceaster, the others also learn about the dimensions of the impending catastrophe for which they have to play the concert of their lives, a heavy responsibility for some teenagers. Tiara and Company decide to save their friends despite not knowing what they are going to do. Moments of confusion and acceptance occur in the other orchestras as our princess flies to town thanks to the faithful servant.
Chapter before the climax acts as a transition, not only revealing things we may have wondered about or not, but it answers them. It's a little tricky trying to establish a critic and opinion on an anime whose purpose is to entertain, which means nothing more than what it wants to show, and which in a way is only promoting a product. Despite the inconsistencies, the series remains at one point that is not unbalanced and tries to take advantage of the two main themes: Idols and Mahou Shoujo. The series doesn't give more than it wants, it doesn't try to give you a deep message (on top of the typical one), and it works because it's not sophisticated. I have a feeling that all of that was definitely set out in this chapter. There is no drastic act that changes the ending, but everything is within the expected range and it works for him.
The truth is revealed
Any series would lose its charm and its secret if it told you from the beginning: you have to learn to sing because you are the protagonist, besides, this is the only weakness of the monsters that will attack in a near day, most likely in this one Chapter will be finale. Much charm would be left out. When we started the anime we didn't think there would be one final battle, I even expected confrontation with monsters in every chapter, especially in the forest, but no. One of the truths that are revealed to us is the fight against monsters. This is not a mere confrontation, but they give it the meaning it deserves that the last chapter winked at with the soldiers and the witches. The confrontation between humans and monsters is the unexpected within the expected.
Academy, magic, orchestra and monsters
The monsters are serious, so they must participate, not just the protagonist's orchestra, but all available orchestras. The director informs the directors of the orchestras and Anna Tiara that the academy was built on a seal that Flora left to protect the city and its people, but that it needs to be reinforced with the mana of the citizens to keep it on Keep going. This not only makes people human, but gives them meaning and reasons to defend them. The orchestras are not battalions, but they are protectors of happiness and their outer weapon is human happiness. It's consistent in your world.
To close this issue of the severity of the problem, I just add: it is so serious that they should not comment to citizens because they would panic. The most painful truths are those that must be kept hidden.
When Tiara spoke to her sister, she learned the real reason she didn't want her to leave, because she knew Mamuceaster was going to be attacked soon, for which she only wanted to protect her younger sister. When he wants to speak to Eliza again, it turns out that she had gone through a portal into the city mentioned above.
Tiara's decision is a little hasty (but the anime is near the end), despite the fact that it suits her personality. There's no real dilemma like: did I stay here with my friends and are we safe or do we go and take a risk? Even the girls did not get into such a dilemma, optimism wins.
Tiara who made up her mind gets the help of her friends, as they also say: Come on, we'll come up with something. Go to help without knowing how to help yourself. The most important thing is to be in the center of the events. The truth is that in times of crisis, something always needs to be done, even if you don't know what to do. In the event of a disaster, hands are missing and they also use magic. With more reason to leave, they will not be stressed as much. We already know what they're going to do, but there are other ways to help like evacuating citizens, checking sectors, etc. The only thing that doesn't convince me is Anna's airplane boat, which almost knocked me off my chair.
Big sister decisions
In conclusion: Here I ask you, what would you have done? The choices Eliza had to make are almost parental choices, noticeable by her absence (and that's another interesting point that I think the anime isn't going to develop). When two brothers have the most of each other, one of them must mature and make the difficult choices that are generally designed to protect his younger brother. Eliza seems to me to be the most complex character, both because of her past, her story and her changed attitude. None of this is unfounded, and even if you don't address them fully, it shows much greater depth.
If I'm not mistaken, there is only one chapter left and the anime ends and almost the season ends too. I can say that the theory of Eliza, tiara, and the tiara is true. We have seen Eliza with blood in her mouth as she advances, but not from battle, but from illness. We'll know what's going to happen and I hope there will be a lot of music if not disappointment, betrayal and shame.
