Female Participants
Akira Hayasaka
Ultimate Hitman/Internet Sensation
Voiced by: Luucarii
With her sassy nature and witty humour, it’s no wonder that Akira became the Ultimate Internet Sensation just weeks after her debut online. Her level headedness made her unique to her adoring fans as they admire her authenticity.
Despite this, it’s strange that nobody’s ever seen her outside of her videos and conventions. Some people jokingly theorise that she’s a stealthy hitman for the yakuza, but that’s just a ludicrous theory, right?
- Action Girl: Is secretly the Ultimate Hitman. Is noted by Takeshi to be strong and exercises a lot.
- Animal Motifs: Serpent.

- Mysterious Purple: She's hiding a big secret and is purple.
- Nervous Wreck: According to Denshi, she's actually a worrywart deep down. She once bought him the wrong ice cream flavor and panicked that he'd kill her over it.

Ultimate Fashion Designer

She created her own ethical clothing line at the age of fifteen, earning her the title of the Ultimate Fashion Designer.

Ultimate J-pop Idol
Voiced By: Ellie
Chou Yoshida, commonly known as Ultimate J-Pop Idol ‘Chousiria,’ is a bubbly sweetheart that has stolen the hearts of many. Her adorable looks can easily smite any person who looks her way, so it’s no surprise her popularity quickly arose when she originally debuted in her old idol group.
Even without her idol persona, Chou is still well mannered and polite, almost to the point where she can be too formal with others. She’s also a very patient individual, and doesn’t speak out when she’s annoyed. When angered, however, is an entirely different story.
- The Ace: Chou has skillfully garnered a lot of attention as the Ultimate Idol.
- Animal Motif: Butterfiles as shown as in her dress.

Ultimate Game Designer
Voiced By: Mi-Mi
Avid game enthusiasts around the world have heard of ‘Bani’, an alias used by the Ultimate Game Developer, Itsumi Yoko. Her work has appealed to both people looking for entertaining gameplay and those who want to experience a story that tugs at their heartstrings.
Although she is praised online, in person Itsumi’s distant and defensive nature makes her hard to approach. It would be easier for her to open up once she’s given a comfortable space and some time alone.

- Picky Eater:
- Pink Is Feminine: Her primary color is pink.
Ultimate ???
Voiced by: Aji
Behind Izanami’s outgoing demeanor and charming smile lies an enigma. She seems to have forgotten her Ultimate talent, and her prowess in numerous fields doesn’t help to narrow it down either.
Although Izanami may be amiable and playful, finding amusement in teasing others, something far more grave lurks behind her pleasant exterior.
- The Ace: She's good at anything and everything.
- Ambiguously Evil: With how she acted towards Akira, whether she is well-intended or not is a hard question with no real semblance of an answer.

- Cosmic Motifs: her dress has constellations,her ribbons and shoes has stars and there is a moon on her head.

- Go-Getter Girl: Is talented at everything she does.
- Head-Turning Beauty: Downplayed: She has attracted the looks of Katsuhiko, Hideyoshi, Tomoya and even says that Yumeo joined just to be with her though he denies this.

Ultimate Manga Artist
Voiced by: Jason Brady
Starting her manga career at the young age of fifteen, Otome earned the title of the Ultimate Manga Artist after her psychological horror manga sold three million copies worldwide. Her work never ceases to amaze considering her astonishing art and storytelling capabilities.
However, Otome is the epitome of insolence as she constantly spits vulgar words out of her mouth, but her grumpiness stems from a lack of proper rest due to her insanely packed schedule. When she’s refreshed, Otome is surprisingly down-to-earth and laidback—just a casual teenager.

- Heavy Sleeper: Loud yelling from Takeshi doesn't even seem to be noticed by her.
- The Insomniac: Thanks to her manga work, she barely gets more than three hours of sleep a night.

Ultimate Itako
Voiced by: Brookuayy
Born into an extremely traditional household in the countryside, Rei was raised and trained to become an Itako due to her blindness. She gained recognition after people decided to ask a spirit medium like her to solve a murder, resulting in more visitors to her house, and thus, she eventually earned the title of the Ultimate Itako.
Rei may be cute and bubbly, but she surprisingly has a god complex of sorts, unwilling to talk to others if they aren’t as talented as her. Reckless and moving to the beat of her own drum, she does not listen to the others’ advice and charges into dangerous situations without thinking twice.
- Blind Mistake: Among other things, Rei initially doesn't realize she's been kidnapped.

- Disability Superpower: As an Itako, she's blind and uses a cane to get around. The tradeoff is she can commune with spirits.

- Jerk with a Heart of Gold: She's less of a jerk and more of a Narcissist who refuses to speak with people who aren't on her level, but Rei is very devoted to her cultural traditions and doesn't want them to be lost to time. She also genuinely appreciates Akira's support when she talks about it.
- Token Mini-Moe: The shortest out of the entire cast.
Ultimate Criminologist
Voiced by: Artimmiss
Although Shion doesn’t remember anything about her talent, she’s known to the masses as the Ultimate Criminologist who single handedly curbed the crime rate of her own prefecture.
Compassionate and caring, Shion is quite friendly and loved by all, but she’s the farthest thing from a pushover. She may be nice, but she will lecture those who do anything offensive or ill-mannered. While Shion is a sweetheart to others, she treats her younger twin in a vastly different manner.

Ultimate Debater
Voiced by: Jason Hall
Formalities and etiquette are a priority in Katsuhiko’s life. Shrewd and assertive, he tolerates no amount of idiocy and discusses all matters seriously. These traits are to be expected from the Ultimate Debater.
He’s a realist through and through, not hesitating to shoot down idealistic views with his carefully formulated arguments. However, it is comical—and perhaps endearing—to see him talk about the things he’s passionate about in such a highbrow manner.

Voiced by: Ramen in a Cupboard
Kyouran’s hospitality and gentlemanly behaviour make it all the more shocking to learn that he’s the Ultimate Con Artist, a sly schemer behind numerous frauds, including the notorious one billion yen scam.
Not much is known about him, not even his name—Kyouran Murashita could easily be an alias. His kind eyes have an off-putting glint, as if he can see through everything you say. He promises never to lie to anyone, but who’s to say that a conman will stick to his word?

Ultimate Therapist
Voiced by: thegreatjudgni
You wouldn’t expect a narcissistic and overconfident person like Tomoya to be everybody’s new best friend. Despite his gigantic ego, he truly has a heart of gold. The atmosphere around him becomes lighthearted when Tomoya cracks jokes to keep everyone’s spirits high.

Ultimate Forensic Pathologist
Voiced by:Tomato VA
Born with the face of a prince, Yumeo’s good looks attract everyone… until he opens his mouth, and all that comes out of it is utter disrespect and rude comments. Many people are also taken aback when they learn that he’s the Ultimate Forensic Pathologist and that he enjoys working with dead bodies more than he enjoys being around others.
Uncooperative and aloof, Yumeo is a loner that trusts nobody, ignoring anyone trying to converse with him. He does things his own way and is easily irritable if anybody interrupts his work.

The Host
Voiced by: Lumisau
Kou is an android who also acts as the overseer of the killing game at the Ultimate Award Ceremony. While he’s technically forcing the awardees to brutally murder each other, it’s only because he’s following the will of the mastermind. Kou personally doesn’t bear any ill intent towards the awardees—he only functions as a messenger.
