Kazuya Souma

Kazuya Souma (ソーマ・カズヤ, Sōma Kazuya) is the main male protagonist of Genjitsu Shugi Yuusha no Oukoku Saikenki series. He is an earthling who was summoned to another world as a hero, but with the accurate announcement of the previous king, Albert Elfrieden, he became the King of Elfrieden Kingdom and to avoid rebellions of people thinking Kazuya has usurped the throne, the king gives his daughter's hand in marriage to Kazuya.

Because Kazuya introduced himself to others using the Japanese form of family-name/surname first, most people in the Kingdom think that "Souma" is his given name, thus referring to him as "King Souma". Only a few know that "Kazuya" is his given-name, while "Souma" is his family-name.

Personality
Kazuya is considered as the title goes, a realist and holds great respect for the writings of Machiavelli and Sun Tzu. Initially unsure of himself after suddenly being handed the crown of Elfrieden, Kazuya eventually gains confidence in implementing his reforms and advancing the standard of living for the citizens. He is very caring of his Queen Consorts and follows the advice of his late grandfather to protect his family at all costs.

History
Kazuya is 19 years old modern Japanese person and a university student who just graduated when his grandfather dies. Before his grandfather's death, he tells Kazuya to get married and live a fulling life. Shortly after the funeral of his grandfather, Souma was suddenly summoned to the Kingdom of Elfrieden, out of desperation, due to the kingdom's inability to pay for war tributes to the Grand Chaos Empire. Unwilling to be handed over to the Empire, Souma instead convinced the King of Elfrieden that it was possible to raise the money to pay the tribute, as well as implement reforms and plans to solve the food shortages, strengthen the army and improve the overall economy. Alfred Elfrieden was so impressed that he decided to abdicate his position as ruler and hand it over to Souma. He also engaged his daughter Liscia Elfrieden, to Souma.

Much to everyone's surprise, Souma actually managed to raise the money to pay the war tribute in two days, by selling off unneeded national treasures. Furthermore, by using the Royal Jewel Broadcast as a kind of mass-media system, he was able to gather the subordinates he needed to solve the food crisis, improve the economy and entertain and inform the masses. His usage of modern-day tactics and ideals of Earth also helped him win the Five Day War against the Three Dukes and Amidonia, which later resulted in the annexation of that nation.

Currently, he is engaged to five women, Liscia Elfrieden, Aisha Udgard, Roroa Amidonia, Juna Doma and Naden Delal.

Liscia Elfrieden
Liscia is the First Primary Queen and is a strong-willed individual. At first she didn't know what to make of the newly-instated king and he did not act like a hero. However, in time she would fall in love with Kazuya and would become pregnant with their first child a year later. Kazuya loves her just as much.

Aisha Udgard
Aisha is completely loyal to Kazuya and takes her role as his personal bodyguard seriously. She is deeply in love with Kazuya and is happy to be his Second Primary Queen.

Roroa Amidonia
Roroa is the Third Primary Queen and has a kind of friendly rivalry with Liscia for Kazuya's affections. However, she looks up to Liscia as a kind of big sister and does find Kazuya to be a 'fun person' to be married to.

Juna Doma
Juna Doma is the First Secondary Queen and is in love with Kazuya. She finds his ideas and realism to be invigorating.

Naden Delal
Naden is the Second Secondary Queen and is his bonded Dragon. She is grateful for Kazuya in helping her realize her potential and is in love with him.

Physical Abilities
Being a regular person from Earth, Kazuya doesn't have much experience in either combat or physical training. Though later on, he does start training in order to increase his physical strength and learn Swordsmanship for self-defense, but his level is around a fresh recruit solider.

Mental Abilities
Kazuya is far more adept in terms of social economics than most in Landia. Due to his knowledge of modern civilization and how the economy affects the populace, he is able to enact reforms and innovations which improve the overall standard of living for the people of Elfrieden and later Friedonia. The success of such methods and innovations are even copied in the Gran Chaos Empire.

His knowledge of the tactics of Sun Tzu and modern warfare also gives him better insight in terms of military actions. His deception tactics during the One Week War greatly impressed Georg Carmine and even made Excel Walter shudder at the thought of how Kazuya's world had experienced such things.

Magical Abilities
Dark Element: Upon being summoned to the Other World, Kazuya gained the ability to use "Dark Element" Magic, which are Unique Magic that can't be categorized under the other elements and are more personalized form of magic. Because of its nature, "Dark Element" Magic is a rare magical element. Since Kazuya is transferring a part of his consciousness into an object to manipulate it, he can also see and hear everything through it, and they can even move independently without any directives from Kazuya. The power and functionality of the magic is based on the weight and form of the object, thus giving Kazuya various usability depending on the object. The control over object become more proficient and easier, if its in the form of an living creatures like toys or dolls, and allows him to simultaneously control more object at the same time. Kazuya can showcase his full potential, if the object is in humanoid shape, since his transferred consciousness can manipulate the humanoid doll shape more easily. He can even make the humanoid doll use various weapons and become proficient with their usage along with them. The effective range of "Living Poltergeist" is around 100 meters for objects which aren't "dolls".
 * "Living Poltergeist": Its the ability to manipulate objects by transferring the users consciousness into them.
