無数に現れるサンドウォーリアーズを迎え撃つ道外流牙とレクトル。
レクトルは、かつてアユラを救うために放った禁断の儀「救陰放我の術」の代償により、石化した左腕の痛みに苦しんでいた。
一方、ヒデンの思念に導かれ界楼ノ間に戻った莉杏を待っていたのは、リュメの命を狙おうとするエルミナ,の姿だった。それぞれの戦いが混沌を極める中、ついに金色の輝きがサガンの闇を照らす……！そして、"砂の王"ホラー・ガルザスもまた、その姿を現すのだった。
Dogai Ryuga and Rector intercept the countless Sand Warriors that appear. Lector was suffering from the pain in his petrified left arm due to the cost of the forbidden ritual "The Art of Salvation of Yin and Ego," which he once released to save Ayura. Meanwhile, Rian, guided by Hidden's thoughts, returns to the Kairounoma, where she is met by Elmina, who is trying to assassinate Lume. As each battle rages into chaos, a golden glow finally illuminates Sagan's darkness... ...!
And the "King of the Sands" Horror Garzas also made his appearance.
