With Yachiyo in low spirits, Iroha and company leave her behind and head for the Memory Museum. Touka Satomi, a friend of Iroha’s sister, Ui, awaits them there to give them a lecture about the truth of Magical Girls. Yachiyo’s past memories give her a push, and she decides to go find Iroha. However, at that very moment Iroha is already in the midst of a "vicarious practical learning" course prepared by the Magius.
In the same way, we call females
on their way to being Witches "Magical Girls."
Y como ustedes se acabarán
convirtiendo en brujas,
Y como vosotras os acabaréis
convirtiendo en brujas,
Comme vous deviendrez des Magi,
des sorcières,
Allo stesso modo, noi chiamiamo "Maghe" gli individui 
di sesso femminile che diventeranno "Streghe".
Portanto, vocês, que vão se tornar Bruxas,
podemos chamar de "Garotas Mágicas", não é?
