When a Chisel boy named Ermand, turned eighteen, he was invited to join Agledon Magic University for Spellcasters. Known for its contemporary magic education and special training, Agledon was the best option for anybody, but there was a major problem.

He didn't have a magic school certificate.

However, keeping this secret away from the college authorities, Ermand starts his first day there. He finds support from a few students, whom he starts friendship with. Life in AMUS can never be boring, but there was always a thorn in the rose.

Through his first year, he had to learn advanced spellcasting and magical powers that would make him a true Defender. At the end of the first year, everybody should gain their Aslehm - a power every advanced and learned Spellcaster achieves during the end of his teens. If he failed to gain it, it could risk his promotion to second year, his secret exposed, and finally into expulsion. Can a boy who hasn't learned elementary magic ever do right? Will he achieve his Aslehm? Will his secret remain a secret? What are the secrets that are dwelling in and out of the college?
