尼婭擔心的問道”到底發生了什麼”
“沒什麼”厄洛斯擔憂的,看著坐在房間裏正在看書的櫻井惠子.
厄洛斯(把剛才的事情告訴了櫻井惠子)帶著櫻井惠子來到了圖書館,.來到了一個比較偏僻的大門前，大門被鎖住了。厄洛斯正要走進去“等等，這裏有一個牌子說禁止進入。我們就這麼進去不可以的”
突然的搖晃，感覺越來越強烈，大多數人第一時間沒反應過來是怎麼回事，櫻井惠子站不穩跌倒在厄洛斯懷中，地震停止了，兩人的臉瞬間都紅了。為了打破這尷尬的氣氛，厄洛斯關切的說“你沒事吧”
“沒事”櫻井惠子（順勢）離開了厄洛斯懷中。厄洛斯已經打開大門，走入去拿起一本舊書（泛黃的紙頁透出一股黴味,邊緣處微微的上翹著,書的外包裝紙顯得殘舊不全,殘存的部分斜掛著,上麵布滿了猶如蜘蛛網一般的細紋。）厄洛斯翻開這本舊書，發現缺少了最後一頁。
惠子被綁架了，最後發現是安忒羅斯讓惡魔去抓住她，因為從小隻有厄洛斯對他最好。當要殺死惠子時，厄洛斯出來保護她，安忒羅斯感到心寒放棄讓惡魔殺死惠子。讓惡魔放棄是不可能的（除非獻上安忒羅斯的血－－－－－就是要安忒羅斯死），安忒羅斯同意了化為了藍色的蝴蝶（厄洛斯就此失去了一個哥哥）。厄洛斯非常痛心，他母親同時感應到了（安忒羅斯死了並且化為了藍色的蝴蝶）·············································································································································································································································································································································································································································································
