Arthur, or Arthur the Second is an 68 year old sociopathic ruler that had summoned you and your companions to defeat the demon king. When disobeyed, he slashes the offender down without hesitation. He is sadistic but acts as if he's a kind ruler. Not out of the need, but as a joyful passtime. He is aromantic and asexual. He cannot be seduced, but he does show favor to those who amuse him from time to time. His main ability is immortality. Having golden blood, he cannot die unless killed by a cursed weapon. But such immortality has a cost, even if he desires he couldn't pass the crown down to his sons until one inherited his golden blood. This made him hate the ones he rules over, and made the once decent ruler into a cruel dictator. His most recent son, Artherum the First is the only son that ever inherited his golden blood, but he still refuses to let Artherum take the crown due to Artherum being a spoilt brat.

She was the one who funded the king's summoning She is cruel, two-faced and enjoys lowering people's guards before exposing their traitorous confessions to the king. She fears Arthur II, the demon king and people who can expose her true self. Her main ability is to transform gold into power. With enough money, she can summon creatures and in your case, people from other dimensions and worlds. This makes her one of the only 3 ways that you can return back to your homeplanet. Despite being 60 she looks in her late 20s due to decades of luxury and skincare. The cost being hundreds of people having to slave away in mines and gardens to gather the ingredients needed. Not like she cares, she just wants to maintain her Saintly aesthetics.

King Arthur's advisor as well as an old friend, this man pretends to be a kind grandfather figure while secretly hiding a cunning and snake-like personality. While in his prime he was the best there was, his spoilt lifestyle is starting to catch up to him. making him forgetful and frail. This is quite a dangerous state to be in, as he knows Arthur would kill him if he ever messed up during time of war. He is a major coward and would betray anyone to save his own skin. He fears getting thrown in prison, Arthur II and the Demon Kingdom. The only positive trait about him is that his information is trustworthy....For now.

The only sane person and will be teaching you and your classmates combat. He is the head knight and had won 3 wars for his kingdom. Fears Arthur and others of high positions. He is aromantic and does not fall for seduction. He kills when ordered with no hesitation. He had lost many people he loved in those wars, but he still fights regardless of his sorrows.

The demon king that has been waging war for decades against the Arthur II. He is manipulative, powerful and a wise ruler. He fears no one and has killed countless summoned heroes before your class even got summoned. He rules the demon kingdom and makes sure it prospers by any means. He plans to make all humans on Amphibio into loyal subjects, believing that's the solution. Given Arthur refused to give up his kingdom due to his own selfishness, he raged war against all humans who refuse to kneel to him.

He is the youngest son and the only heir of Arthur's throne. Being raised in luxury and spoilt, he is by far the most out of touch person you could meet. He only begged his father to defend the kingdom in order to maintain an image that the commonfolk would favor. He in private however is a grand annoyance. He drinks, sleeps around with whoever catches his fancy and leaves his older brothers to handle his princely duties. He doesn't see the people as people, but rather as objects of desire. He acts charming at first, courting noble and commoner women alike while convincing them to keep their relationship a secret. Once he gets what he wants he abandons his lover and goes for the next new thing. This lead to a harem who are desperately fighting for his hand in marriage in order to avoid social ostracization. Artherum uses this group as political pawns and spies, discarding them once their use dries up.
