This map takes you on journey from an eerie, slow start reminiscent of a horror movie. You wake up in the middle of a labyrinth. Off in the distance, you see a man in a cave, pale as moon, hunched over a box of some sort. He spots you, then the drop comes, and you're thrust around, running every which way to evade the horrific monstrosity chasing you, for he is not what he seems. He is a cannibal.

You finally manage to evade him, but your sense of urgency is heightened. You run faster, you take longer strides, and you jump at the slightest of sounds. You You haven't seen him in a while, so you steadily start to calm yourself. You continue trying to look for a way out, yet it seems fruitless, until a scream from behind catches you off guard. The second drop takes hold. This time, you can't run.

You're in combat with a cannibal, desperately trying to stay alive. Holding him back with all your might. Countering his insanely quick movements with all your ability. You see an opportunity to strike, and shove your knee into his stomach, causing him to reel back in pain. You then elbow him to the ground, and kick him powerfully in the side of the head.

You're safe for now. And as if by chance, the exit seems to be right behind him. You walk to the exit, but just before leaving, you turn around. You can't help but feel a little bit sorry for him.

(Lyrics)
The song is a Doujin arrangement of the Touhou theme Faith is for Transient People, and the lyrics appropriately follows the inner monologue of Kochiya Sanae.

The title roughly translates to "Even the Endless Wind's Trajectory", which is a metaphor that no matter where you are or what the situation is, time will continue to keep flowing and life will move on with or without you. The word for "Trajectory" in Japanese is also a pun where 軌跡 (kiseki) is the same sound as the word for "Miracle", 奇跡 (kiseki). This could be a hidden meaning where despite having its ups and downs like the wind across the Earth, being able to live life is a miracle in of itself.

The first half of the song has Sanae commenting about how she is the only one able to achieve her goal of "eliminating the transience of humanity", which is backed up by the fact that she constantly refers to herself in the first person. The line "Bidding farewell to ‘warmth’" implies that she sacrificed a lot in order to try and achieve her goal, and "Only looking at what I should accomplish" shows how determined she was.

By the second verse and pre-chorus, it is implied that she had failed to accomplish her goal, or at least came out with an undesirable result. She begins speaking in past tense as if reflecting upon her mistakes. "My precious people shed tears, Unable to do anything about it" shows that the people that she was trying to protect were incredibly upset at what happened. "I couldn’t find the words" connotes at the time how disappointed she was in herself for failing.

By the end of the solo, it is suggested that Sanae had accepted her failure as a lesson to learn from, and is now happier with her current situation. "What I wished for were kind days" implies that she recognises her mistakes and is deeply sorry for what happened. "I don’t need any miracles now" tells us that she has accepted her past, the line "A peaceful life like a gentle breeze" shows what her new desires are, and "I don’t need any special powers" tells us that she is moving on from her past to happier times.

The song itself changes intensity a lot during its play in response to the lyrics, for example the music enters the (first) chorus and is most intense when she is ready to execute her plan, and is very calm during her acceptance of her responsibilities. The mapping reflects this well by changing SVs constantly with respect to how intense certain parts of the song are. The map is also accompanied with a full storyboard which helps accentuate the different parts of the song's intensity.

Overall the lyrics of the song takes the listener on a trip of how Sanae's story began as her as a naive young girl with one ambitious goal in mind, and by the end of the song how she has grown up to be able to live with her mistakes and move on in life.

tl;dr: A trip through the endless wind's trajectory.
