I'm several years late to the game ;; but I just wanted to know if it was ever revealed who exactly "Professor Rokuno" was and his relation to the Kamiyas? He seemed to have known at least one member of the family considering that the two people he seemed to be talking to were named "Narumi" and "Kamiya" but are we supposed to know based on the information from the game or...?
Also in trying to figure out more, I noticed that Akane's father (Kyoya) appeared to have been trying to "escape" from his past that dealt with his own father (Kanata) before he became abusive towards both Shino and Akane so I was wondering if it was also ever revealed what exactly happened to him or if we were just supposed to infer it might have been similar to what Hinata went through?
