Golden Boar Lord

Description
One of the three great demon lords, with a wild-boar head and hairless body. The last king of the fallen Orc Empire.

After being captured during a war with Saga Empire, Ancient King Yamato managed to befriend the Orc King and his retainers thanks to her charms and unique skill "Friendship". Unfortunately brutality towards demi-humans in Furu Empire and a betrayal by Weasel allies, forced the Orc King to overuse his unique skills and finally turn into a demon lord.

He was later defeated along with his generals by Yamato during a battle for the Saga Empire Capital City, with only Ga Hou surviving on the Orcs side. The battle was later portrayed on a grand painting currently displayed in the Ougoch Capital Museum.

Ougoch Capital
During his first visit to Ougoch Capital, while tracking members of Wings of Freedom, Satou stumbled onto a summoning ritual, where Sara along with two other teenage oracle priestesses from Parion and Garleon temples were kidnapped to be sacrificed during the summoning of the Golden Boar Lord possessing Sera, as instigated by two of his demon generals (In LN the two demon generals were possessing the other two priestesses and were pulled out by Satou after he used the Demon Sealing Bell).

After Satou defeated the Red and Blue demon generals, having gathered enough energy from the deaths of the present Wings of Freedom members and his two retainers, the Golden Boar Lord finally resurrected emerging out of Sera's back, killing her in the process.

After gathering Sera's body and blood into his inventory, Satou continued to battle the Golden Boar Lord who described him as an "artificially created cultivation" because of his absurd power but lack of experience. The fight was initially equal as the Boar King's layered shield armor was thick enough to catch Holy Swords and Satou being fast enough to dodge the Boar King's attacks. Finally Satou gained the upper hand when he uses the intermediate level magic Furnace Flame (Forge) to destroy the Boar King's layered shield armor and then destroyed half of its body with his holy swords.

In response the Boar King transformed into an undead using one of its unique skills "Banpufutou" and regenerated his body. Satou then used Furnace Flame to destroy his magic shields whilst initiating a three-stranded spiral spear attack with the spear Holy Spear Longinus. Half of Boar King's body got destroyed and regrew with translucent-like tentacles coming out of hand and retaliates with its [Instant Death] skill.

After seven more successions of destruction and revival the Boar King summoned black flame magic swords made of its bones (capable of burning Heavenly Dragons) while Satou swapped Longinus with Durandal. Unable to injure his enemy, Boar King was finally corned as his magic swords kept getting destroyed by Durandal.

Eventually Satou had no choice but to draw Galatine whose holy flame was strong enough to overpower the Boar King's rate of regeneration and the demon lord admitted his defeat while being burned down to the point that not even ashes remained.

Followers
The six orc generals that fell during the final battle against Ancient King Yamato continued to serve their king, now as greater demons, and schemed to bring about his resurrection (in order of appearance):
 * Black (fire, wind, acid, petrification, dark, lightning magic) (primarily a CQC fighter) - Appeared in Seiryuu City during Satou's city tour with Nadi. Later a lesser demon spawned from his severed arm created the Labyrinth of the Devil and succeeded in restoring Black's main body, only to again have him face Satou who came to the bottom of the labyrinth to finish the job. (In LN he only appeared once, when summoned by the lesser demon during the final fight in the Labyrinth of the Devil).
 * Red (Space Magic) - Appeared during the Wings of Freedom summoning ritual in Ougoch Capital's withered labyrinth.
 * Blue (Gravity Magic) - Appeared during the Wings of Freedom summoning ritual in Ougoch Capital's withered labyrinth.

 * Pink (Defensive Magic) - Appeared during the first attack on the capital, has a connection to an artifact capable of harvesting and storing Miasma and as long as it had miasma he could heal himself, unless he was hit with a forbidden class spell.
