Footsteps of Horror (aka The School Festival)
Exposed is chapter 60 of the Boku wa Tomodachi ga Sukunai light novel series. It is chapter one of volume six.
After being asked why Yozora was present in his dream of ten years ago, a puzzled Kodaka was informed by Rika that he was shouting Yozora's name when he was under the hypnosis. Grasping for an excuse, Kodaka reasoned with the others that it was a random coincidence that she appeared in his dream. Yozora then nonchalantly revealed to the others that she and Kodaka were childhood friends, much to everyone's shock. Kodaka affirms this fact.
