Shou Hibayashi (As RAM)

During the events of the original DRcade, Shou took on the identity of RAM, who served both as his online handle and name for his Avatar during games of DRcade. Like his actual self, he is selectively mute, and uses a device in order to speak. 

His goal as RAM was to help his sister, Mori, run the game, as originally Mori running the game on her own was too much for her to handle. Together with the living AI, they made the original DRcade into a successful - though a bit glitchy - game for people to play and unwind from everyday life. RAM even is the one who hosts the RPG event sessions, mustering his courage to make the sessions fun for everyone despite his severe anxiety. 

Eventually, when the living AI in the game whisks him away, he and Mori are forced to make a choice. Though they see the living AI as their family, both him and Mori decide that they have to shut the game down - even at the cost of the AI no longer remembering the times they've had both in and outside the game. This makes RAM wary about rebooting the game himself and, when someone shows interest in doing so, worries that the same mistake might occur once more.
