Magical disciplines go brr, and Ernest Howard just wants to beat people.
A few years ago, magical caves appeared and sucked its surroundings in Titan Kingdom, which resembled Britain in early Victorian era. People in Titan found magical water in those caves and they could gain supernatural powers from it. However, if they lacked knowledge in certain disciplines, they wouldn’t gain any powers. Thus they established a few magical disciplines.
A reincarnated person, Dunno, sent by God to prevent the doomsday in Titan due to those magical caves.
