William Twining

The main character of our story, William Twining is a dogmatic realist who believes in the power of science and disregards everything else. On one hand, he is the heir of the Twining house and the best student in his prestigious school, with high hopes for the future. On the other, he is the reincarnation of King Solomon, who ruled Israel and controlled 72 pillars, aka demons. Now, there is a crisis in Hell and the pillars are coming to William one by one to get him to Hell and choose the next Emperor. However, William refuses to choose anyone and still insists that angels and demons do not exist. Now the demons are at his school and William's life has become a roller coaster of the supernatural.
