Seihi

Seihi serves as the chief of Sosshi Village, a small rural settlement targeted for its magic stones.

He dies confronting Heath Grice and his allies alone, protecting his village at the cost of his life.

In the original manga version of the story, this character appeared without a name.

In the anime adaptation, he is given the name Seihi and expanded into a key figure in Magna Swing’s backstory.

Seihi is rough around the edges, with a fondness for gambling and a tough, old-school attitude.

Despite his vices, he has a strong sense of duty and will stake his life to protect his people.

He believes deeply in the idea of what it means to be a “man” in a moral and spiritual sense.

Through his actions and teachings, he emphasizes responsibility, courage, and standing up for others.

With younger people like Magna Swing, he is strict but caring, scolding them when they go astray.

He prefers to correct bad behavior not just with words, but with training and real-life lessons.

Sosshi Village Chief

As village chief, Seihi is responsible for the welfare and order of Sosshi Village.

He even resorts to gambling poker matches, at one point winning everything off Yami Sukehiro and Magna Swing.

After stripping Yami and Magna of their possessions in a poker game, he “charges” them in the form of a request.

He asks them to deal with a rampaging wild boar as compensation, using the situation to benefit the village.

Past Ambitions

In his youth, Seihi once dreamed of joining the Magic Knights.

However, he never actually took the entrance exam, leaving that dream unfulfilled.

This unfulfilled ambition likely shaped how he viewed young mages like Magna Swing.

Rather than pursuing his own path further, he chose to support the next generation from the sidelines.

Confrontation with Heath Grice

When Heath Grice and his group invade Sosshi Village seeking a magic stone, Seihi does not run or hide.

He stands up to them alone, confronting the intruders despite knowing how outmatched he is.

In this showdown, he is killed in action, dying in an attempt to shield his village from danger.

His death underscores both his bravery and the harsh reality of ordinary people facing powerful magic users.

In the anime, Seihi and Magna Swing share a long-standing, almost mentor–student relationship.

They are portrayed as old acquaintances, with Seihi having known Magna since Magna’s wilder youth.

After Magna acquires his grimoire and starts acting out, Seihi harshly scolds him for his behavior.

He then takes Magna under his wing, training him and drilling into him the true meaning of being a “man.”

Through this guidance, Seihi teaches Magna that strength is worthless without responsibility and heart.

He actively encourages and supports Magna’s goal of joining the Magic Knights, pushing him toward that path.

Because of this, Seihi becomes one of Magna’s most important benefactors and moral anchors.

Magna’s later growth as a Magic Knight is heavily tied to Seihi’s early influence and teachings.

Seihi’s exact magic attribute is never clearly identified.

However, he is shown creating and using metallic weapons, such as metal swords and metal arrows.

These manifestations suggest that his magic likely relates to metal creation or manipulation in some form.

Even though he never became a Magic Knight, he is clearly a capable combatant by ordinary village standards.

His willingness to face Heath Grice alone, using his magic to fight, highlights both skill and bravery.

Nevertheless, the power gap between a rural village chief and an elite enemy mage proves fatal.

In the manga, this village chief character appears without a name or deeply explored background.

He is simply a brave chief who dies defending his village from Heath Grice’s attack.

The anime adaptation greatly expands his role and identity, officially naming him Seihi.

It also establishes his personal history with Magna Swing and his influence on Magna’s development.

By making him Magna’s mentor figure, the anime strengthens the emotional weight of his actions and death.

This change turns Seihi into a symbol of the older generation’s hopes, passed on to the next through Magna.
