In order to prevent the novel's heroine from being revised, Yuu must perfect his love of little sister moe. Yuu and Suzuka both attend Sakura's radio program as guests, and Yuu begins flirting with Suzuka while on air as part of his training to become moe for little sisters, but...
I'm a "kuudere" little sister, 
so I'm killing my emotional response.
Ich bin eben die kleine „Kuudere“-Schwester,
da muss ich meine Emotionen unterdrücken.
Soy una hermanita kuudere,
suprimo mis emociones.
Soy una hermanita kuudere,
suprimo mis emociones.
Je dois être froide mais languissante.
Je cache mes émotions.
Io sono una sorellina "kuudere",
quindi sto soffocando ogni tipo di emozione.
Eu sou uma irmã kuudere,
então eu matei meus sentimentos.
Мне попалась «кудере»,
так что я не выражаю эмоций.
