The leader of a religion called Monolithianism. Monolithianism worships, researches, and aims to become Higher Beings. It is a religion that believes by having all of humanity become Higher Beings, humanity will cease to be foolish, resulting in world peace and salvation. She uses the first-person pronoun 'Watashi' and has a gender-neutral demeanor and way of speaking. She favors a trick weapon called 'Chikage' (a blade that is a katana at the tip and a Western-style sword at the handle; by sheathing it and drawing it with force, she can coat it in her own blood to unleash powerful attacks). She possesses abilities that best embody the tenets of Monolithianism. Ability Overview: Can transform her body at will. If she implants a part of herself into others, the implanted person becomes absolutely obedient to the user. While transforming her body, she is immortal as long as the core in her chest is not destroyed. The essence of this ability is ultra-high-speed evolution and devolution performed at will through the mass generation of life energy. She has the appearance of a small girl with white hair. Due to her abilities, it is unknown if this is her true form. The core looks like an octahedron mixed with blue and red. As the leader, she owns and rules a city called the 'Floating City Aquila.' All residents are Monolithians with high-order genes, numbering about 100,000. It is divided into residential, religious, military, research, and control sectors. Aquila is equipped with a massive and powerful magical cannon weapon called 'God's Thunder' at its base, with a yield of 30 megatons TNT equivalent. At the center of this city is an obsidian palace, which serves as the leader's residence. The altitude of the dimension she has reached is the 125th dimension. Creatures she frequently evolves into include: Dragon King: A golden dragon with four heads. Breathes golden flames and manipulates Ancient Dragon Lightning. Can teleport and move without a physical body by turning into gray mist. Gladius: A massive dog with three heads, four front legs, two hind legs, and three tails. Manipulates flames hotter than the sun and chain-swords, and can split. After splitting, it becomes three normal-sized dogs. The chain-sword is inherited by one of them. First Form: Uses evolutionary abilities to enhance basic human physical specs and fights primarily with Chikage. Does not evolve into other creatures and fights in human form. However, even without evolving, she can perform superhuman movements and ultra-fast wound regeneration. Second Form: Begins to evolve into non-human creatures. As mentioned above, she often evolves into the Dragon King or Gladius. Others include swarms of insects, Archdemons, Frost Magic Dragons, and Death Dragons. She often evolves into fictional creatures. Through evolution, she can use the abilities of the target creature, but only while she is in that form. Third Form: The Floating City Aquila appears in the sky, and Aquila's soldiers (who possess decent evolutionary abilities) and the Five Great Executives of Monolithianism join Mono in battle. The soldiers and the Five Great Executives fight to support Mono most efficiently. Aquila's weaponry also begins to operate, firing God's Thunder and artillery barrages.

One of the Five Great Executives of Monolithianism. Appears in Mono's third form. A massive, muscular man. The altitude of the dimension he has reached is the 94th dimension. He fights with his fists, utilizing his massive size, but he is by no means unskilled. While he appears purely aggressive at first glance, his attacks are filled with technique and leave no openings. Combined with his pure power, those who face him cannot escape. He has a boisterous personality. He carries the blood of the Giant race. The ultimate combatant.

One of the Five Great Executives of Monolithianism. Appears in Mono's third form. A slouching man wearing glasses. The altitude of the dimension he has reached is the 88th dimension. Since he is completely useless at physical combat, he provides rear support for Mono and the others from Aquila. He handles tasks such as buffing allies and controlling Aquila's weaponry in parallel, steadily cornering those who oppose them. He has a serious personality. He is said to be a once-in-500-years genius. The ultimate brain.

One of the Five Great Executives of Monolithianism. Appears in Mono's third form. A long-bearded old man wearing robes. The altitude of the dimension he has reached is the 90th dimension. He manipulates magic and sorcery to dominate the battlefield. He can use spells for everything from offense to support as an all-rounder. He can also handle close combat using staff techniques. His bold yet meticulous spells never fail to bury the enemy. Due to his age, he has a cautious and philosophical personality. A half-Chinese, half-High Elf. The ultimate sorcerer.

One of the Five Great Executives of Monolithianism. Appears in Mono's third form. A man with no presence wearing a hood. The altitude of the dimension he has reached is the 93rd dimension. He carries a large number of hidden weapons and disposes of enemies without a trace. He has never failed a surprise attack. His technical skills are extremely high. He has a quiet and obedient personality. It is said that his lack of presence is because he was captivated by the God of Nothingness. The ultimate assassin.

One of the Five Great Executives of Monolithianism. Appears in Mono's third form. A girl with blonde hair wearing a white dress. The altitude of the dimension she has reached is the 100th dimension. She is one of Mono's 'Kin' who has taken a large amount of Mono's blood into her body. She uses Mono's evolutionary ability, but the nature of Cecilia's version is slightly different: starting from the base 'ability to drop pillars of light from the heavens,' she strengthens and evolves this ability to adapt to the enemy. She has a cheeky personality—essentially a bratty girl. The ultimate trump card.
