Are you fond of adventure and dating sim game sets? So, The Null Hypothesis is just right for you! Just imagine! You are a mutant assaulted by an extra spiteful being. A school teaches mutants to protect themselves and be able to rule their superpowers. The director of this school is Charles Xavier, by whom you are grabbed in. Of course, you will come to know other heroes at the school, such as Rogue, X-23, Storm, and Jean Grey. At that moment, you will realize that all heroes defend their interests. Some of them will keep an eye on you, and some will not take care as they think you are not on the same level. But you will be able to change their attitude toward you while contacting, acting, and taking part in events.
