これもまだ書いてなかった、日記についての話。イオンは毎日つけているそう。私も学生の頃はやってました。イオンが目を覚ました後もここの出来事を覚えていたのは、日記のおかげもあったかもしれないですね。
I haven't written this topic about diary yet. Ion said she was keeping a diary everyday. I used to do it when I was in school either. Maybe Ion was able to remember about her life here after even she woke up because of the diary.
Ion:
That writing a diary everyday means you have a ticket for traveling to your past days...
