A 14 year old boy called Suzuki Iruma was abandoned by his parents and adopted by a kindly Demon school headmaster called Sullivan as his new grandson. He is now attending a school in the demon world where his new “demon” grandfather works as the principal. Life at the new school is exciting for the new pupil – if others find he is a human, he could be eaten. This is the great story of life as a human boy attending a School for Demons with his demon friends.
