Shin Wolford is a boy, who used to work in an office in Japan, but after being killed in an traffic accident, is reborn in another world, where he learns magic from his adoptive grandfather, Merlin, and grows up sheltered from the world.

After moving to the royal capital, Shin prepares to take the entrance exam for Earlsheid Magic Academy, a high school for magicians. However, his far-disproportionate skill in magic already ensure that he is in a class by himself.

During their first full day of school, Shin and the others get a tour of the academy. After Kurt's father is summoned by the king over Kurt's behavior, he is grounded, while Kurt's mother invites his former magic teacher over to speak to him.

News of Shin's exploits proves impossible to keep under wraps, and many more applicants wish to join the study group. The king orders a joint investigation into the appearance of the new demonoid. The study group gains two new members.

Mark takes Shin and the others to his family-run blacksmith shop, where Shin commissions a new sword, and buys a gift for Sizilien. The Blusfia Empire begins preparing to go to war. Shin is formally decorated for his heroic actions.

Following the routing of an imperial invasion force and demon attacks, Diseum orders the students at both the magic and military schools to increase their combat readiness, resulting in a joint training exercise for both schools.
