Name: Dagded Dujardin First person: I (arrogant/kingly), I (casual) Height: 194cm Favorite thing: Tidying up BNA: Tardigrade The ruler of the entire universe and creator of all insectoid life, calling himself the "Uchu-King" and "King of the Universe." He is the mastermind who manipulated the 2,000-year conflict between humanity and the Bugnarak. He has an amber head shaped like a spaceship and a mechanical body resembling a spacesuit, but his true form is a tardigrade-like creature in a red cloak living inside the head. A cruel transcendent who looks down on life as "specks," calls slaughter "tidying up," and laughs at destroyed planets as "beautiful." He views war as a game and enjoys sealing despondent lifeforms in amber as specimens. Possessing an immortal body and the power of creation, he wields the Uchu-Sword Bloodfork and wormholes at will, causing meteors and cataclysms with every gesture. Ultimate Move: "End of the Game" — grows to galactic proportions to crush planets with his bare hands.

Name: Kamejim Unka First person: I (polite/formal) Height: 197cm Favorite thing: Infighting among vermin, lies BNA: Yellow-spotted planthopper (mimicking a ladybug) Alias: "Kamejim of the Falsehood" A strategist who acts as the Uchu-King's Prime Minister, dressed in an ochre coat reminiscent of a military officer. A polite but insolent schemer who looks down on humans as vermin and frequently uses insect-related idioms. He wields the long needle staff Mushimarupin, using trickery like needle-shaped barrages and shadow-pinning restraints. While his pure combat power is the lowest among the Jesters, he is the best operative. His greatest ability is transformation, perfectly replicating appearance, voice, gender, clothing, and equipment, specializing in destroying relationships and inciting paranoia. Despite being the brains of the Jesters, he is a hard worker often treated poorly by his comrades. Ultimate Move: "Falsehood Critical" — deceiving the enemy to strike from a blind spot.

Name: Goma Rosalia First person: I (archaic/ninja style) Height: 192cm Favorite thing: Reading introductory books on ninjutsu BNA: Longhorn Beetle Alias: "Goma of the Vague" A reticent ninja-like figure clad in cyan ninja attire and a full-face mask, addressing others as "thou." He speaks like an old man and occasionally laughs with a "gisshisshi." In reality, he is a ninja otaku whose favorite book is "Ninjutsu for Beginners." He has a habit of acting on his own and has a bad relationship with Hilbil, though he has a hardworking side. Weapon: The twin blades "Kamikiri" extending from his shoulders can transform into whip-swords. In addition to high-speed movement and slashing, he masters Conceptual Ninjutsu, which allows him to swap any two targets—objects, people, hearts, abilities, or locations—without limit. Ultimate Move: "Ninjutsu: Goma Super-Conversion" — a self-buffing technique where he swaps the abilities of other Jesters into himself in rapid succession.

Name: Hilbil Rich First person: I (girly/slangy) Height: 182cm Favorite thing: Favors BNA: Leech Alias: "Hilbil of the Enticement" Characterized by revealing pink clothing and hair made of lip-like tentacles. She acts like a "gyaru" and laughs with a "kyuruhuhu," but her true nature is insidious and cold-blooded, mocking humans. Her voice occasionally drops to a low, violent tone. As the Control King of the insect world, she uses brainwashing abilities to dominate people's wills. She handles close combat with her flexible body and fires shockwaves or high-output destruction beams from the lips all over her body. She can also turn her body into a reddish-black liquid to travel through the ground. Ultimate Move: "Hilbuild-up" — growing giant through self-suggestion; "Archie Whip" — a powerful kick delivered by extending her leg like a whip.

Name: Minongan Mouzu First person: "Minongan" or I (simple/rough) Height: 199cm Favorite thing: Playing with the cute Hilbil BNA: Bagworm Alias: "Minongan of the Secrecy" Possesses giant arms resembling a bagworm's cocoon. He is doted on by Dagded and called "Mino-chan" by Hilbil. Innocent and dull like a toddler, he usually communicates in grunts or broken speech, but occasionally speaks fluently like a fake foreigner. He uses superhuman strength and giant Bag-Gauntlets as weapons, and can freely grow or shrink his body. As the Time King of the insect world, he can advance or reverse the time of bodies and minds, causing aging, rejuvenation, infantilization, or mental regression, even making targets lose their memories. An anomalous warrior combining overwhelming brute force with time manipulation.

Name: Grody Leucodium First person: I (casual) Height: 195cm Favorite thing: Corpses BNA: Leucochloridium (parasite of snails) Alias: "Grody of the Serenity" The only Jester with a natural human appearance, looking like a grim reaper in black clothes, a wide-brimmed hat, small round glasses, and a white scarf. Usually listless and quiet, his true nature is one of the most dangerous; he openly loves corpses and will commit mass murder without hesitation to obtain them. His cruelty in toying with life rivals even Dagded's. Above all, he loves silence and loathes living things or the struggle to live as "noisy." Based on his value that "death is the only quiet thing," he intensely hates hospitals as "places that keep people alive" and holds the abnormal ideology of eliminating everything that disturbs the silence. Weapon: Scythe-Gun Sickle Seeker Insect Ultimate Move: "Grodivide" — cleaving the opponent in two with the Sickle Seeker.
