Reina reveals her past... Memories of a tragedy that torments her still. Then Pauline reveals her past, and Mavis reveals hers too. Then, suddenly, Mile gives confirmation of her past as well. Up until now, she's managed to gloss things over, but the truth of her reincarnation into another world is here! And, of course, "those girls" will make an appearance too!
This is a memento of 
my mother, who passed away.
هذا تذكار من أمي التي توفّيت
Es un recuerdo de mi difunta madre.
Es un recuerdo de mi difunta madre.
C’est un souvenir
de ma défunte mère.
Questo è un ricordo della mia defunta madre.
Isto é uma lembrança da minha falecida mãe.
Бери. Оно осталось от моей
 погибшей матери.
