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!
Thank goodness! Mavis-san's simple 
past was good for something, then!
هذا مُطمئن! ماضي مافيس-سان البسيط
كان جيّداً إذاً
Ein Glück, dann war Mavis’ enttäuschende
Vergangenheit ja zu was gut.
¡Qué alivio! El pasado simplón
de Mavis sirvió de algo.
¡Qué alivio! El pasado simplón
de Mavis sirvió de algo.
C’est cool, ton passé sans histoires
aura été utile.
Meno male! Il passato facile
di Mavis è servito a qualcosa, allora!
Que ótimo! O passado sem importância
da Mavis-san serviu para algo!
Вот здорово! Скучное прошлое Мэвис
 оказалось очень кстати.
