Right now Kurumi-san is just 
as aroused as Yuki-san gets
Gerade ist Kurumi-san
so erregt wie Yuki-san,
Sus niveles de excitación están 
a la par con los de Yuki-san
Sus niveles de excitación están 
a la par con los de Yuki-san
Elle est excitée 
de la même façon que Yûki
In questo momento Kurumi-san
 è eccitata quanto Yuki-san
Nesse instante, a Kurumi-san está 
tão excitada quanto a Yuki-san fica
Сейчас Куруми в том же состоянии возбуждения, 
что и Юки при активации проклятия.
