As the other members of DearDream become busy with individual projects, Kanade is still searching for something he can do. He talks to the members of their senpai unit ACE about his concerns, and they tell him about a secret reference room hidden in the D-Four office building...
you can't be called a unit if 
you're not watching one another.
لا يمكن أن تُعتبروا وحدةً إن لم تشاهدوا بعضكم البعض
ist man keine Unit, wenn man
nicht gegenseitig auf sich aufpasst.
no pueden ser una unidad
si no cuidan del otro.
no se puede ser una unit
sin cuidarse mutuamente.
senza prendersi cura degli altri
non si è mai un vero gruppo.
vocês não são um grupo se não 
 estiverem de olho uns nos outros.
