This is one of the few songs that are heard explicitly throughout the series, its lyrics are very deep and denotes the feeling that the soldiers of the Legion of Recognition have in particular. This OST by Hiroyuki Sawano is quite detailed in certain passages of the anime.
"Were we born to lose and let Goliath win?"
If we use this part of the lyrics of the song to make an analogy with the events of the anime, we clearly notice that it refers to the Titans when it says "Goliath" why lose? For mankind has no way to defend against them and civilians tend to be easy prey for them.
"100 years more on fire"
Since Singeki shows us the first chapter, we hear more than one character say that peace in Paradys is going on for about 100 years. Then, having a surprise blow by the Titans, it is born of the soldiers to want 100 more years of peace.
"When we die we ask our brothers once again,
If the meaning of our lives was worth a penny,
Our world rusts but it will surprise us. "
Each time a soldier dies, he does so believing that his death was not in vain; however, according to Shadis, the former commander of the Legion of Recognition, the deaths of his companions do not help at all to obtain more information about the titants, a point that is quite criticized by Erwin Smit, the commander who followed him, because the point It was not to send soldiers to fight and now, but they had to have a plan A and a plan B always. To avoid human losses. And it is Erwin who manages to make a kind of Coup d'etat in Paradys, thus overthrowing the false king.
"Going down to show you what to do
How to die with honor, dignity "
Undoubtedly this is the saddest part of the series in general, because nobody expected the sad end of Erwin, who guided by his faith in finding the truth did not mind having one less arm and leaving with his men straight to death to "distracting" the Titan Betia, while Levi, the captain, would act as an ambush. Of course, Levi was totally against his commander's decision, because without him nothing would be the same. Erwin mentioned that if he was not going to die with the other soldiers, none would dare to go on their own accord because the commander himself had to give them that will to die for the truth.
