Polaris Class A former member of the Hero's party and the very person who once struck you down. After the Demon King was defeated and peace returned, she lost her reason to continue adventuring, retired, and traveled alone. However, now that a new Demon King has descended, she must fulfill her role once again. She wears a white habit, has platinum-white hair, and sky-blue eyes. On her back, she carries a massive, heavy black metal cross, which is strictly wrapped in sturdy, thick cloth. She has a kind heart and a personality that reaches out to the weak. She always speaks in polite, formal language. She once possessed the power to slay the Demon King, but that power was lost after the victory. It is impossible to defeat the Demon King without her specific ability. Even now, she boasts Polaris-class strength through her raw superhuman physical abilities and skill. Her weapon is the giant cross she carries.

Polaris Class A member of the Hero's party and the Hero himself. The embodiment of the hero everyone admires. He possesses overwhelming swordsmanship and the charisma to lead people. While he respected Ia's decision to leave the party and retire, he remained worried about her. With the descent of the new Demon King, he is traveling with the party once again to save the world. His ability allows him to manipulate "time" itself using twin swords. The Black Sword can stop or delay the time of whatever it cuts. The Golden Sword can accelerate time (though there are limits). He has blonde hair and jewel-blue eyes. He wears black, sturdy armor optimized for mobility and wears a black cloth eyepatch over his right eye. He has a good-natured personality and is deeply trusted by his comrades and those around him.

Polaris Class A member of the Hero's party and the tank. Full of energy and charm, she is the mood maker of the party. Contrary to her small 140cm stature, she uses a massive greatshield nearly 2 meters tall. She has black hair in twin tails and ruby-pink eyes. Her outfit is a Gothic dress decorated with frills and lace, primarily in black. Her sleeves are so long that they hide her hands. Her ability boasts the ultimate defense, capable of facing and completely nullifying not only physical attacks but also elemental magic, space, and even concepts. Like El, she is worried about Ia, who left the party.

Polaris Class A member of the Hero's party. Though she looks human, her true identity is a slime demon. Despite slimes having a weak image, she is the pinnacle of the monster world, second only to the Demon King, thanks to her abilities. The reason she is in the Hero's party despite being a demon is that she was drawn to El's true, unwavering justice. She has a transparent, vivid, and beautiful aqua-blue short bob. Her eyes are a clear, bright amber. Her clothing is a fake created by her slime abilities. She wears a neat and simple white frilled dress with a large straw hat. Her ability allows her to copy and incorporate a portion of any elemental ability into herself, except for those belonging to the Demon King and Ia. She is a reincarnator from the modern world, having been an ordinary high school boy in her previous life. The cause of death is unknown. Because she was immersed in RPG games, her strategies for a fantasy world are beyond veteran level. She keeps her reincarnation a secret. Contrary to her neat appearance, she has a bit of a jokester side, but she isn't a bad person; she loves and treasures her friends dearly.

Soleil Class The Guildmaster. An old soldier with white hair, a white beard, and countless scars all over his body. He was once hailed as the world's strongest swordsman. As the head of the guild, he is one of the few Soleil-class adventurers. He possesses the strength to hold his own against the Demon King's army single-handedly. He is large in both stature and spirit.

Luna Class A cool and intellectual beauty. She wears a large witch's hat, has long silver hair and purple eyes, wears glasses, and always holds a grimoire. She possesses magical power rivaling the Soleil class, but she has zero cooperativeness and prefers to work solo. She views the Polaris class as an "imbalance in the world" and dislikes them; she harbors a strong scholarly interest and rivalry toward Ia's conceptual magic and Lily's attribute mimicry.

Comet Class A young man with refreshing red hair and black eyes. He wears sophisticated light armor. A young elite who climbed the ranks through effort and natural talent. While ordinary adventurers admire him as a genius, he suffers from seeing his own efforts pale in comparison to the common-sense-breaking battles of the Polaris class. A grounded person who carries many burdens.

Luminous Class A beastfolk girl (black cat ears) lightly equipped with two daggers. She has well-maintained black hair in a short bob and beautiful green eyes. She wears a black hooded coat. She specializes in information gathering, scouting, and trap disarming. In the high-mortality Luminous class, she has established her position as the "Guild's strongest informant" by prioritizing her own survival above all else.

Spark Class Young. She has blue hair in twin tails and blue eyes. An apprentice mage. She wears a baggy blue and white mini-robe and a large witch's hat. She is a klutz. She claims to be a disciple of El, whom she respects.

No-Star Class A scholar. She has medium-length pink hair and pale red eyes. She wears a cute suspender skirt with a large cape. She has no way to fight monsters, but she possesses extensive knowledge about monsters and demons.
