I did read on a few comments and topics that Hyper has a route himself, but no matter how hard I try, I can't find a way to start it. Could someone help me? Even if it's just a hint, I would appreciate the help here ;-; He's my favorite character, i really wanna go after him

For the time being, all you need to do is play the game.  Hyper is part of the main route, you shouldn't miss him   =3
