A cut version of this song (which stops right after the climax) can be found in Deemo, another one of Rayark's games.
At the start of the new chart, around combo 250, a set of drag notes and a hold note form an IX (The Roman numeral for 9).
At the end of the new chart, 2 hold notes start at the same spot on different scan line movements to create a sword-like visual, and this repeats 4 times. These notes also sync up to a very long violin note that would be impossible to chart on a single movement.
In the old chart, near the climax, A zig-zag of many drag notes overlap a long hold note. The drag notes shape a heart, and the hold note resembles the sword that's pierced the heart of the character in the cover art. This pattern also closely resembles an upside-down version of the cycon for L10: In Memory of Maneo.
