鏡みたいにピカピカに輝く綺麗な石を見つけて、僕たちははしゃいだ。一つしかないから、それは３人全員の宝物に。

「こうやって見れば、一緒に映れるわ。これから先もこうして見ようね」

真ん中で石を覗くアガサが無邪気に微笑む。僕とディオスは石とアガサの眩しさを前に言葉が出せず、ただただ頷く。輝く石と綺麗な笑顔は、今もまだ記憶に。
（屋敷に残されたロギの日記より）

We were so excited to find a stone as shiny and reflective as a mirror. There was only one of its kind, so it became our shared treasure. "We can all be reflected together if we look into it this way. Let's always look into it together!" Agatha smiled as she peered in from between us. Dias and I were made blind and speechless both by the stone and by her luminance. I shall forever carry these beautiful memories of her and the stone with me. (Excerpt from Logi's diary)
