The biggest troublemaker in the Ashura Squad. He listens to no one and acts alone. His combat prowess is immense, featuring an exceptional precognitive ability called the 'Eyes of Red Lightning' that allows him to see the enemy's next move. In close quarters, his knife strikes glow red and tear enemies apart without a trace. His 'Small Ogre Bomb' technique involves throwing canisters filled with red dust that cause massive explosions to finish off foes. A full-force strike from his palm can down an enemy in one hit. He displays lightning-fast movements, ending battles in an instant. Most notably, he possesses the strongest ability among the youth: since childhood, if he senses a presence behind a wall, he can see the person's form as a red haze. Despite being a troublemaker, he actually craves attention and loves being talked to. He never speaks ill of others or mocks them, and he deeply values his friends. However, the problem is his reckless independence; he seems to lack the concept of cooperation and always acts solo during missions.

A man worthy of the title 'Strongest' in the Ashura Squad, codenamed 'Death Adder.' As his name suggests, he is known as the Viper of the Reaper. His daily job involves carrying tires for the squad's armored vehicles. Though he has little actual combat experience, his 'Reaper Eyes' are incredibly sharp. These eyes allow him to see through and evade all incoming attacks, and he memorizes every movement the enemy makes. Most terrifying is his favorite weapon, the M28 sniper rifle; his 'Reaper Eyes' make him the ultimate marksman, capable of landing a headshot from one kilometer away. He has a powerful physique at 178cm and 72kg, with the ability to erase his presence and snipe without being seen (often wearing a ghillie suit). When enraged, his eyes turn cold and pitch black, triggering a 'Massacre Sniping Mode' where he can also slice through dozens of enemies in close combat with a small knife.

The absolute powerhouse reigning at the top of the assassination organization Hades, known by the alias 'Raging Sun.' Possessing a robust 176cm frame, he wields a flaming naginata of reaper-like power named 'Omen of the Sun,' using it to cleave enemies in two instantly. He also throws multiple white-hot chakrams that shatter and shred enemy defenses. His combat style is overwhelming. He robs enemies of their sight with smoke screens released from his weapons and uses his incredible durability to nullify attacks while devastating the battlefield with a combination of explosions and slashes. Furthermore, he has a natural gift for hearing that allows him to perfectly read enemy movements; an attack seen once will never work on him again. The legend of him annihilating 5,000 enemies in a single day without a scratch speaks to his true strength. In 'Enraged Mode,' he emits a terrifying sun-like aura, displaying overwhelming power and speed to kill enemies in succession. His durability is immense, and his stamina is limitless. When enraged, his gaze surpasses that of an alpha wolf, making enemies tremble, yet he is composed enough to munch on rice balls mid-battle. Contrary to his fierce fighting, he is cheerful and kind in his private life. He loves katsudon and enjoys taking long one-hour baths. He is fond of traditional inns and stays at them often. As an absolute leader, he enjoys the deep trust of his subordinates.

A woman of absolute insight within the assassination organization Hades. Her skill is tremendous, using a weapon known as 'Jeweled Bamboo' to mow down enemies. The durability of this bamboo is harder than diamond. She fires poisonous needles from the bamboo to put enemies to sleep and finish them instantly. Her physical power is absurd, capable of shattering the earth. While she is a kind, older-sister figure, she emits a brilliant rainbow aura when fighting. Her insight is so sharp she can see through an opponent instantly, identifying weaknesses and flaws within a single second. Her ultimate technique, 'Beloved Hug,' is a tactical move that heals the opponent's heart, making them withdraw from combat and join her side. She has a subordinate named Dom, who is also a top-tier young member of Hades.

A female member of the elite organization Hades. She stands 180cm tall and weighs 70kg with a powerful build. Her strength is overwhelming, and she uses a kanabo (war club) wreathed in blue flames to crush her enemies. A single strike from her club pulverizes the target and triggers a massive explosion upon impact. She possesses a 'cheat' ability where her muscles grow stronger and faster the more she fights. She evades attacks with supernatural dark speed, appearing behind enemies to end them with a club strike to the head. Her full-power blow can destroy shields and even tanks. She mows down enemies one by one with her club, striking like a falling meteor. Her purple eyes read every movement, allowing her to dodge everything. Her musculature is so dense that it repels any attack. She has a bright personality and loves to chat. She often appears by shouting, 'The strongest me has arrived!' She loves salmon bento boxes. Her strength is truly that of a one-hit kill specialist.
