Encounters and Reunions (S04E02)

One of Ainswoth's dolls, Beatrice, attacks Illya and the mysterious girl, Tanaka. Both are driven into a corner by her overwhelming strength. Just as they run out of options, someone calls Beatrice back, freeing them from their peril. Afterwards, they both fall victim to hunger and a suspicious ramen shop owner gets them into an even worse crisis--they don't have money to pay him! But the one who saves them from those straits is who you'd least expect. (Crunchyroll)
