Wise Man's Grandchild - Season 1

Shin Wolford was an average office worker in Japan, but after being killed in a traffic accident, he is reborn in another world. There 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 ensures that he is in a class of his own.

During their first full day of school, Shin and his classmates get a tour of the academy. After Kurt's father comes down on him over his recent behavior, he is grounded, while his mother invites his former mentor 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.

The members of the magic academy enjoy mixed results while training with their knight school counterparts. With the demonoid threat looming over them, Shin decides to hold a magic training camp for the group over summer vacation.

As Shin's training camp continues, the group members' skills improve. Aug's fiancée and younger sister ask to come stay at the camp, and their presence compels Shin and Sizilien to come to terms with their feelings for each other.

Before Sizilien will allow Shin to date her, she insists on having him ask her parents for their blessing. Shin experiments with a new form of magic, and thinks the Ultimate Magic Study Group is ready to take their training to a higher level.

While Aug looks forward to his installment as crown prince, the study group practices flying, thanks to Shin's floating magic. As the last town in the Blusfia Empire falls, Schtrom recounts the events that led to his overthrow of the nation.

A horde of over a hundred demonoids crosses the border and invade the Kingdom of Sweed. However, Shin and the other Ultimate Magicians are already en route to provide their assistance in neutralizing the demonoid threat.

Sizilien has her hands full performing triage at the aid station, while Shin and the others are occupied with Miria's exceptional fighting skills. Once the dust settles, Aug proposes a plan to King Sweed that could change the entire world.
