In the real world, Hikaru has disappeared, and everyone has forgotten he exists.  Futaba visits his insane mother, hoping to get some answers..
I can't let him go alone!
Ich darf ihn nicht allein lassen!
¡No puedo dejarlo irse solo!
¡No puedo dejarlo solo!
Non posso lasciarlo andare da solo!
Não posso deixar ele ir sozinho!
Я не оставлю его!
