is a Japanese manga series written and illustrated by Yunosuke Yoshinaga. It was serialized in various Flex Comix magazines from September 2006 to October 2022, with its individual chapters collected into 20 volumes. It was adapted into six 50-minute anime films.

Plot The story is centered around a young man named Rygart Arrow, a resident of a world where people can use "magic". This magic is the ability to control and empower quartz, doing many things from creating light to operating machinery to riding giant mecha called "Golems". Rygart, however, is one of the few exceptions; as an "un-sorcerer", he cannot utilize quartz, making many aspects of life difficult as well as being looked down upon by the rest of society. Despite this, in his youth he managed to befriend Hodr and Sigyn, the future King and Queen of the Krisna Kingdom; and Zess, the younger brother of the Secretary of War of the Athens Commonwealth.

Years later, Rygart is reunited with Hodr and Sigyn where he learns the Athens Commonwealth has begun an invasion of Krisna. Rygart is also shocked to learn that Zess is leading one of the strike forces. While at the capital, Rygart discovers that he has the ability to pilot a recently discovered ancient Golem which cannot be piloted by magic users. Despite its ancient origins, the golem possesses capabilities and systems far more advanced than the current Golems, and could be key to turning the tide of battle. While hesitant at first, Rygart soon gets involved in the war between Krisna and Athens, in an attempt to save Hodr, Sigyn, and even Zess.

Characters

The Kingdom of Krisna

Rygart is the series' main protagonist at the age of 25. He was born an "un-sorcerer", meaning that he cannot use magic, unlike the majority of his world's populace. Before he left to see Hodr, he worked on a farm with his brother who is also an un-sorcerer, and because of this, his father sold all Quartz operated tools and worked with tools without Quartz to make the boys stronger and to keep them from feeling like outcasts. After his father took out loans, Rygart was able to attend Assam military school where he befriended Zess, Hodr, and Sigyn where the four of them were known as "the four problem children of Assam's Military School", with him being known as the "King of Make-up tests". He hates violence and believes he could win via his opponent tiring out but is willing to fight more directly and violently with his enemies. He becomes the pilot of the Delphine, an ancient Golem designed for only an un-sorcerer's use as a Heavy Knight for Krisna. He originally joins the war to protect his brother and friends, but later admits he is really fighting to protect Sigyn who he really loves. Initially, Rygart is extremely hostile towards Girge when they are teamed up, yet acknowledges the other pilot's skills as a pilot. Rygart eventually comes to recognize Girge as an 'outcast' like himself, and is devastated after Girge sacrifices himself for Rygart. Rygart later spearheads the counter assault on Binonten and has a rematch with Borcuse, this time managing to kill the General, but is left with only more questions about his role in the war. After Borcuse's death, Rygart is promoted to Warrant Officer and given the title, "Hero of Krisna".

Sigyn is the 25-year-old Queen of Krisna and Hodr's wife and a close friend of Rygart. They went to the same military school as him, where she was known as the "Mad Scientist" for secluding herself in the school's lab for up to 3 days and nights at a time without eating or drinking. She pursues a career of science and cares deeply for her friends, to the point of pointing a gun at Rygart upon first seeing him to ask why he did not show up at her wedding and confirm that he does not hate her. While she is the Queen, she rarely acts like one as she usually spends her time in the castle maintenance workshop tinkering with machines alongside the royal engineers. Even though she and Hodr are married, they both sleep in separate chambers. It is later revealed that Sigyn was in love with Rygart during their days in military school. When Rygart left school to take over his father's farm, Sigyn attempted to confess her feelings to him, but he purposely ignored her, not wanting Sigyn to live a life of ridicule as the wife of an . Even after her marriage to Hodr, she still loves Rygart. While complimenting each other on their hair, Cleo says "Blonde hair...Is much prettier" to which an exhausted Sigyn replies "Black...For one single moment...I...Really....Liked it". Sigyn later petitions Hodr for a divorce, but he has yet to give her an answer. Regardless, Sigyn has been spending more and more time with Rygart in an attempt to help him overcome the guilt and trauma he has experienced on the battlefield.

Hodr is the 25-year-old king of Krisna and Sigyn's husband. He befriended Rygart at Assam military school when he ditched class to help him save an owl after he spotted him from his classroom's window. He was known as the "Crowned Prince" for staring at the sky and scoring failing grades. He does not want to be king, but tries to be a good leader and cares greatly for his people's lives. Despite being married with Sigyn, he does not shows any feelings for his wife and is aware she loves Rygart. During the cease-fire before the Battle of Binonten, Hodr reveals to Rygart that he has lost all romantic interest in Sigyn and that she has petitioned him for a divorce but later put it on hold. He then berates Rygart for not being honest about his feelings for Sigyn. In truth, he still loves Sigyn. However he suppresses it because he always knew Sigyn and Rygart have always loved each other. He has a younger sister named Lindy who is married to a General from the Orlando Empire.

Narvi is a 24-year-old female Upper Class Heavy Knight from Krisna. She previously served under General True before being assigned to command her own squad. As a squad leader she has a tendency to be brash and impulsive, always trying to be at the front of battle. Her actions are the result of her desire to prove her worth as a field commander, so that she may be able to serve in General True's inner circle of officers. She is devastated after finding that General True was killed in battle. After the Battle of Binonten, Narvi is promoted and becomes one of General Baldr's front-line commanders. She also receives a prototype new-model Golem with greater speed and maneuverability. She has feelings for Rygart.

Nile is Narvi's older brother and a First Class Heavy Knight.

A 29-year-old male Upper First Class Heavy Knight from Krisna who serves as a mech sniper. It is implied that he has a crush on Narvi.

A calm General and brilliant strategist. He is one of Krisna's most prized generals. He serves as a mentor to Rygart on becoming a soldier and is also his Commanding officer. He has a son named Girge but has since disowned him due to the latter killing one of his fellow cadets and injuring 8 others during a training exercise without reason. Baldr was away on border patrol when that incident occurred and has never been able to get the full story from his son or the reasons for his actions. Baldr attempts to ease Rygart's conscious after he delivers Girge's body to him. Baldr has shown great concern for Rygart, seeing how the pressures and traumas of the war have weighed on Rygart's mind, and is afraid they may drive Rygart down the same path that ultimately 'broke' his son.

A hot-headed General of Krisna who always immediately runs into the battle without strategy much to the trouble of those under his command. Despite these flaws, he is well loved by the people of Krisna due to donating all of his money to the orphanages of Krisna and even taking care of the orphans himself with two of those orphans being Narvi and Nile. He is killed at the end of Volume 4 due to his hot-headed impatience leading his forces right into an obvious ambush by the Athens Invasion Force.

A tall female military instructor for Krisna. She is an expert in close quarter melee combat.

A gifted mech pilot from Krisna and General Baldr's son. He was formerly serving in prison for killing one of his fellow cadets without reason during training but when Krisna needed more skilled mech pilots for the war, he is granted supervised release and assigned to Narvi's squad to help the war effort. He is skilled in sniping and using a Katana with his Golem, a modified Athens's Artemis and takes the opportunity when given the chance to fight other skilled mechs whether they be comrade or foe. Due to his attitude and past actions, General Baldr has ordered his squad-mates to execute him should Girge try to attack any of them. His instability was the result of the pressure trying to live up to people's expectations who expected him to follow in his father's footsteps. But what may have started his instability was when during his childhood, he and his father rescued a village from a group of escaped prisoners where he allowed his father to shoot him in the leg as a distraction when one of the prisoners took him hostage. Girge fights against several of General Borcuse's elite guard while protecting Rygart and the rest of his squad. He manages to severely damage or disable all of their heavy mechs before finally being disabled and captured. He is later killed by Borcuse by fooling the General into believing he is the pilot of the Delphine.

Rygart's younger brother. Like his brother, Regatz too is also an un-sorcerer.

Commonwealth of Athens

Zess is a 25-year-old soldier of Athens. He met Rygart at Assam military school, where he was called "straight-laced Zess". He was the best pilot cadet in the academy's history and was full of pride. He first met Rygart when Rygart was being bullied and refused to stand up for himself. Zess defended him and quickly befriended Rygart afterward. When he learns his nation plans to conquer Krisna, he leads his Valkyrie Squadron, a small commando strike force of mechs to the Krisna capital in order to make Hodr surrender quickly to spare his friends and their country from the wrath of the main Athens Invasion Army, unaware that the leaders of Athens gave an unofficial condition of surrendering to Hodr: The execution of the whole royal family, including Sigyn. Ultimately his mission is a failure which costs the lives of two of his subordinates and the capture of Cleo. In his last confrontation with Rygart, he is critically injured when his cockpit is crushed. He returns home to his wife and two-year-old daughter, all the while greatly regretting the consequences that awaits Krisna by the main Invasion force. After the death of General Borcuse, and at the request of his brother, he was ordered to lead the second Athenian invasion force. Zess's Valkyrie Squadron Golems are the lightweight mech, Artemis.
