Isabelle in Monster Hunter 4 Ultimate. In the 1.4 summer update (wave 2), Isabelle takes the day off during the fireworks festival every Sunday in August. She will give the player one of the four variations of bopper headgear each Sunday night. Please do not leave anything on stage when you exit. See your favorite characters come to life on stage! I think it becomes easy for fandom to think that it represents all of the SFF community because it’s a pretty diverse group.
