Due to all the villain attacks recently, mostly from the LOV, Principal Nezu had decided to have dormitories built for the UA students for their safety and easy accessibility to the school and school faculty in case of any dangers. Albeit, Class 1A had an uneven amount of girl and boy students for roomates, so Principal Nezu had decided to have one of the boys roomate with the Class 1A vice president and most responsible student, Momo Yaoyorozu.
