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!
I think she'd be useful 
for any number of things.
أظنّها ستكون مفيدة في أمور عديدة
Überlegt, wozu sie sonst noch
alles zu gebrauchen wäre …
Debería servirles
para mucho más que eso.
Debería serviros
para mucho más que eso.
Et elle peut servir
à bien d’autres choses.
Penso che vi sarà utile in vari modi.
E acredito que poderá usá-la
de vários outros modos...
Да и мало ли как ещё пригодится.
