Min Seyi: A girl from the Mundane Guild who absolutely despises the “vermins” ends up transferring to Sekang because of her family’s lack of wealth. She goes to class carrying her prejudiced views with her and stirs the class into conflict, especially when she sees Suzy, the girl she despised the most. During the time, she ends up falling for Baekhyun, and is confliced between her love for him and her values.

Byun Baekhyun: Son of Byun Jihoo, the Ruler of Necromancers. Is forced to attend Sekang High School (the only school that allows students from all of the Four Guilds to attend together) in order to gain experience and knowledge on the Mundanes. He tends to be a bit playful but knows when to be serious. He is a natural leader and sweeps all the girls in Class One off their feet. He is prideful and hates having to depend on others.

    Park Chanyeol: He is a Fire Controller in the Terra Guild who is known as the “happy virus” in of the bunch. Always smiling, always optimistic and open-minded. He’s charming and smart, a very loyal and trustworthy friend. He befriends Baekhyun quickly and the two bring the girls to their knees. Chanyeol becomes attracted to Seyi and also becomes close friends with her.

    Bae Suzy: A half Mundane, half White Witch in the Witch Guild, a pure-hearted girl who is gullible and very emotional. Since she was a rare case, the King of Mundanes allowed her to stay in the Mundane Guild during the school year and to the Witch Guild during summer. However, because of the Witch blood in her veins, she is bullied by her Mundane peers and eventually transfers to Sekang in hopes of living a normal life. But she meets one of her bulliers there, Min Seyi.
