The story begins with the introduction of the main characters Rin and Finis. Rin is an energetic girl who lives together with her grandfather, older sister and younger brother. From a very young age Rin loves to sing and obtains the ability of songs, which allows her to manipulate the power of the elements. On the other side appears Finis, a woman who also obtained the ability to sing. Being a special person, Prince Rudo keeps her in his castle and controls her as much as possible, using her for his own whims. Some time later, a war breaks out, and Prince Rudo forces Finis to participate in it in order to use the song ability as a form of weapon. During the war, the village where Rin lived is destroyed, with only her and her younger brother surviving. Rin's main goal was to go to the capital and become part of the royal orchestra, but while traveling, she heard that there was a person with the same ability as her who was being forced to sing to win the war (Finis), and changed her goal to saving Finis from such a situation.
Although the story up to this point is fine, it feels a bit generic.
But, when does the problem come?
In chapter 7, there was a plot twist, which I personally didn't expect: Finis sings the Song of Mortality, throwing the whole world into chaos. But using said song comes at a price: the user becomes immortal and lives in an endless cycle as she tries to reunite with the man she loved, whose name is Henry.
The problem starts when different timelines begin to exist. I have no problem with timelines as long as the story fits in with the rest of them and makes sense, but unfortunately, it wasn't handled correctly and that created a huge hole in the story regarding Rin's existence.
Contextualizing a bit, in the third timeline (the second timeline is when Finis was in an endless cycle as she altered the order of the world) Finis managed to return to her era but joins forces with General Bazra in exchange for letting her sing the Song of Mortality at the Starsong Festival and being able to destroy the world. Therefore, all this changes the first timeline, and with that, Henry doesn't meet Finis, Henry's allies don't die, etc.
Regarding Rin, the problem is that she is the Healing Song that Finis discarded:
Rin, being the Healing Song, should only have existed in the third timeline, because that's when Finis refuses to use said song. This is confusing, because the first timeline Rin exists, where I could assume she is a normal girl who just likes to sing, but obviously the opposite was shown during chapters 1-7, plus Finis used the Healing Song several times.
In what way would that hole affect? Since Rin shouldn't have existed in the first timeline, Henry should have died during his confrontation with Bazra, Pony Goodlight probably would have been captured by the soldiers, etc.
Putting that aside, the story moves forward "correctly", managing to entertain you and enjoy it. If the story had been fully coherent, I probably would have given it a 7 or a 7.5.
This is a personal note, but the story could have gone a little deeper by adding about 4 chapters more.

CHARACTERS (7/10)
Honestly, there's not much to say about the characters. Overall, the main characters and relevant supporting characters are charismatic and have acceptable development, especially Finis.
ART AND ANIMATION (7/10)
The character designs are simple and the backgrounds are fairly well detailed, making them contrast a bit. The animation is ok, it's not bad, but it doesn't stand out either. It also has CG moments, but they are really few and very short. For an anime that came out of nowhere (I mean, no manga or light novel), it's pretty decent.

MUSIC (SOUNDTRACK AND SONGS) 9/10
Of course, this depends on one's taste, but anyone who listened to its soundtrack or songs, even if they don't like it, definitely can't say it's horrible. I personally loved all the songs, specifically, the Song of Healing along with the Song of the Wind, both with a medieval touch and quite beautiful and partly delicate lyrics; and the Song of Mortality, a powerful song, sad and melancholic lyrics. Both the soundtracks and the songs are composed by a well-done instrumental orchestra, which combines very well with the era in which the characters find themselves. About the opening...I spent the night thinking because it left me with a dèjá vu feeling, and it turns out it was because it gave me huge vibes of Lisa's songs (in case you don't know her, she is a famous singer who created songs like Gurenge from Kimetsu no Yaiba, among others)



Maybe its story is not memorable, but its songs are, which honestly, is what I liked the most about the anime.
Would I recommend this anime? Yes, the anime is enjoyable and short, perfect in case you want to do binge-watching.
Would I watch it again? Maybe, if so, it would be after a long time.
