Background
The PV opens to the narrator thinking about ideas and memories that confuse and corrupt the mind to the point the narrator begins to doubt that what she knows is even true. A graveyard is shown with a girl looking at a grave, she notes that what was the truth became a lie. The narrator notes that her and her sister are likely going to meet the same fate as their mother did.

As the song begins, Luka is shown awakening, the girl who did the narration is seen piloting a mech and fighting in space destroying ships all around her. Throughout the PV flashes and glimpses of the girl and her young sister from the past are seen, the imaginery along with the song suggests that some event tore them apart after the death of their mother. As Luka sings, the girl fights, until eventually a break for the instrumental solo ocurs and the girl is left facing her younger sister, who is piloting a mech also. When Luka resumes singing, more images are shown begin with the young sister in a street with dead bodies around her, eventually the two are shown lying with their eyes closed (dead or asleep) on flowers. As Luka ends the song, the two girls clash once more, there is an expolsion along with flashes of the images seen previously in the PV. As the PV ends, Luka is shown shutting down again.

The song itself talks about flowers throughout the verses, something you find in a garden, each accompanied with a image of corruption:
 * Decadent flowers: bloody memories
 * Lamentation of flowers: graven miseries
 * Pitch-black flowers: memories of oblivion
 * Unprecedented flowers: that keep blooming and dying
 * Flowers of chaos: repeating miseries

The song itself ends by pleaing for someone to rid the rotten world of its mistakes before it is destroyed, as all that is left is "the ash of a flower".
