Nayuta and Miyako walk in on Itsuki, who was naked in front of the bathroom mirror, trying to act out the little sister character in his new volume. Itsuki is everything to Nayuta, and Miyako secretly has some feelings for Itsuki, but Nayuta also cherishes Miyako because she showed her compassion in her time of need. Nayuta invites Miyako to the hotel she’s staying at and immediately gets naked. She then asks Miyako to also get naked for some kind of research for her novel...
I'll have you know that my little 
sister used to be really cute...
Meine Imouto war früher ganz süß.
Te diré que mi hermanita
era muy linda…
Mi hermanita puede ser muy tierna…
Elle aussi,
elle était mignonne, avant.
Per tua informazione la mia sorellina
una volta era davvero carina...
Fique sabendo que minha irmã
 mais nova era uma gracinha...
Чтоб ты знал, раньше она была милашкой!
