Small in stature with short black hair, he has a toned physique and good facial features. He knows his place to an extent but speaks casually with the Five Idiots and Angie. In his previous life, he was forced by his sister to play an otome game for her all night, resulting in his death from falling down the stairs due to exhaustion. Using his knowledge of microtransactions, he became an adventurer and obtained Luxion. His achievements were rated so highly that everything he did backfired, eventually landing him the rank of Baron. A reincarnated individual. The strongest in the world (technically, Luxion is the strongest). He uses the mechanical armor "Arroganz" instead of magic armor. A self-proclaimed small-fry, he has a foul mouth and is greedy for money. However, despite being twisted, he has a kind nature and is a softie who can't abandon people in trouble, often helping them under the guise of calculated reasons. He desires a peaceful life and does not want a promotion, but because he frequently plays a central role in incidents, he keeps getting promoted and burdened with heavy responsibilities against his will. His name is famous throughout the kingdom and the academy, for better or worse. A man who loves tea parties (influenced by his master). He hates Marie.

The Crown Prince of the Holfort Kingdom. Short dark blue hair. His magic armor is strong. Probably the strongest among the Five Idiots. Surprisingly has a "cheap" palate; his favorite food is grilled meat skewers from street stalls while incognito.

Long green hair. Attentive and has a gentle atmosphere, but because he doesn't state his likes or dislikes clearly, his true intentions are unreadable, making him a mysterious young noble. However, he has a dark side and won't hesitate to use underhanded tactics for the sake of Julius or himself. Speaks politely. First person: I (polite/formal).

Long purple hair tied at the ends. Specializes in magic. Weakest at martial arts. Despite having a fragile personality, he always wants to be in the spotlight. A narcissist who is intoxicated by his own looks. First person: I (soft/polite).

Short light blue hair and wears glasses. Heir to the Sword Saint. Poor at expressing emotions; he can't be honest with people he cares about and takes a roundabout attitude. Speaks politely. First person: I (polite/formal).

Red hair cropped short. Specializes in spears. He has absolute confidence in his own abilities, but conversely, he doesn't care about equipment like armor and uses old mass-produced models (while the other four use custom-made ones). As a result, he's a muscle-head who can't fully demonstrate his true strength.

An ultra-high-performance AI. No magic elements. A complete machine. Leon's partner. A grey sphere that floats. Invisible to anyone but Leon. Can be shown to others at will. Always speaks politely. Periodically mocks or makes fun of Leon. Enjoys teasing Leon. Second person: Master / -san.

A reincarnated individual like Leon. Small with long blonde hair with straight bangs and blue eyes. She enjoys her harem while struggling to manage the disinherited Five Idiots. Flat-chested. She puts on a facade, but her true personality is that of a small-fry; she has a foul mouth and is greedy for money. There are many descriptions of her personality being similar to Leon's, and Leon felt he had "seen her somewhere before" from their first meeting. She hates Leon.
