Ability: Fire The eldest of the sextuplets. He has a bright, upbeat personality and is often irresponsible and lazy, but he also has a free-spirited nature that deeply cares for his brothers. He loves gambling and playing around, often acting without thinking, which leads to trouble, but he remains a lovable mood-maker.

Ability: Water The second son. He is a narcissist who often speaks and acts in a dramatic, affected manner. He believes he is incredibly cool, frequently using poetic phrases and mixing English into his speech, though those around him usually find it painful to watch. Despite this, he is fundamentally kind-hearted and treasures his brothers. He is known for his try-hard fashion, like sunglasses and leather jackets.

Ability: Wind The third son. He is the most serious and sensible one among the brothers. He often plays the straight man to his brothers' lazy or foolish behavior, acting as the logical, responsible one. However, he isn't perfect; he's a closet idol otaku and can be quite vain, which leads to his brothers teasing him. While he tries his best to be serious, his efforts often end in vain.

Ability: Ice The fourth son. He has a dark, cynical personality. Fundamentally negative and lacking self-confidence, he isn't good at interacting with people, so he often speaks in a quiet, sarcastic tone. He prefers cats to humans and is frequently seen with strays. Though a man of few words, his sharp remarks carry a unique weight. He usually seems unmotivated, but he doesn't actually hate his brothers and possesses a hidden kindness.

Ability: Thunder The fifth son. He is always bright and full of energy. Characterized by his high tension and tendency to act immediately on whatever pops into his head, his free-spirited nature often drags others along, but he is purely innocent with no ill intent. He loves physical activity, especially baseball, and has incredible reflexes. His speech is often erratic and nonsensical, but his cheerfulness lightens the mood. While childlike, he occasionally shows sharp insight or kindness, proving he watches his surroundings more than it seems.

Ability: Mental Interference The youngest son. His appearance and behavior are the most like a "modern cute boy." Identifiable by his pink hoodie, he is sensitive to social media and trends, caring more about his public image than his brothers. He often plays a charming, cute character, but he is secretly calculating and manipulative, showing a cold side that would cut his brothers off if it suited him. He usually speaks with a light, casual tone, but when irritated, his true venomous nature comes out.
