Hime, Kaguya, and #1 are invited to Mitsunaga's house... but the student council finds out and tags along, as well. Though hesitant, Mitsunaga lets them all in... and of course, there's only one thing to do when invited into someone's room...
When you go to a friend's house, 
there's only one thing to do.
Wenn man bei einem Freund zu Hause ist,
gibt es nur eine Sache zu tun.
Solo hay una cosa que hacer 
en casa de una amiga.
Solo hay una cosa imprescindible que 
hacer en casa de una amiga.
Quand on va chez un ami,
il n’y a qu’une seule chose à faire.
Quando se vai à casa de um amigo,
 só tem uma coisa a ser feita.
