Characters / Heat Guy J

Go To

The denizens of Judoh. A man should beware of spoilers.

Daisuke Aurora

Voiced by: Masaya Matsukaze (JP), Steve Staley (EN, as Steve Cannon)
The Hero of the work, despite not being the title character. A police officer with the Department of Security, Central Headquarters Special Service, he's half of the field team. Their division is tasked with preventing crime before it happens. Daisuke is a good man with a strong sense of justice, though he's a bit on the lazy side.
  • All-Loving Hero: Shows some signs of being this, since he seems to bear no grudges or ill will for anyone but those who do harm to the innocent. He's happy to forgive anyone if they're not acting maliciously anymore.
  • Anti-Hero: Has heroic qualities (desire for justice) and not-so-heroic ones (laziness).
  • Advertisement:
  • Badass Normal: Just a guy ( Albeit half-Celestial, but that doesn't actually mean anything), and he manages to take on androids and people enhanced to superhuman levels.
  • Bishounen: It's partially the art-style, but he's drawn as a skinny blonde prettyboy.
  • Brilliant, but Lazy: He's incredibly capable, but he sure does enjoy lounging on the couch, much to Kiyoko's chagrin.
  • Cain and Abel: The Abel to Shun's Cain, after it's revealed that Shun's the Big Bad.
  • Catchphrase: "Yeah, yeah." and "You piss me off."
  • Contemplate Our Navels: Has a tendency to drift off and wax poetic for... some reason.
  • Cool Bike: His bike is amazing. Not only is it fast and built like a tank, it can convert into a mode to go over water and in a pinch, J can get on it and it'll transform into a mode only he can use.
  • Cowboy Cop: Loves catching baddies, hates oversight and paperwork.
  • Advertisement:
  • Deadpan Snarker: Enjoys dishing out dry one-liners from time to time. It goes with his "bored guy" image.
  • Distress Ball Gets handed this every now and then, captured so that J has more to do. Or in one instance, Kiyoko.
  • Fantastic Racism: Seemingly doesn't like androids. The first episode ends with him telling J he will take him down if he goes rogue, and he brushes J off in his first meeting. Of course, he and J are True Companions anyway so it's more of an Informed Attribute.
  • Hair of Gold, Heart of Gold: Blonde and very firmly on the side of justice.
  • Likes Older Women Has a crush on Antonia, his senior, seemingly showing little interest in the younger, cutesier Kiyoko.
  • Mr. Fanservice: Is seen doing chin-ups on the balcony of his top-floor apartment shirtless.

The titular Heat Guy J, he's an android built by the city (androids are generally illegal in Judoh, J is an exception) as the second half of the Special Service. Appears and speaks like a wise old man, but tends to get his human disguise destroyed in combat.
  • A.I. Is a Crapshoot: The real hitch to the plan to take over Judoh? Daisuke manages to talk J out of his programming to get him back on his side.
  • Androids and Detectives: The premise for the series, he's an android on the police force. With his fedora and trenchcoat he wouldn't look that out of place in a noir movie, barring his hulking frame.
  • Artificial Human: An android who usually wears artificial skin, and wholly sapient.
  • Bad Ass Longcoat: The only time he's not wearing his kickass trenchcoat is when it (and his fake skin) gets burned off in combat.
  • Cloud Cuckoolander: Can come off this way at times, particularly in the next-episode previews.
  • The Computer Is Your Friend: He's a robotic individual, but he's largely built to be good and helpful.
  • Mad Libs Catch Phrase: Dispenses advice starting with "A man..."

Clair Leonelli

Voiced by: Daisuke Sakaguchi (JP), Johnny Yong Bosch (EN)
The first major antagonist of the series. A boy whose father, the Vampire (top crime lord), just died, leaving him to inherit the role. He's more than a bit unstable and as the series goes on, becomes increasingly frustrated with Daisuke and J foiling his plans.
  • Adaptation Personality Change: In the manga, he's not as into lobbing grenades, and not as concerned about impressing his deceased father. And although described on the back cover as being "unstable," really isn't, the way he is in the anime. He also doesn't seem to have the physical and mental health problems he does in the anime, and even has a girlfriend.
  • Affably Evil: He's become this by the end of the series. He's still a criminal, but he's not insane and much more restrained.
  • Ambiguous Disorder: He's... off. The abuse from his father contributed for sure, but he's just a bit strange in an unexplored way.
  • Angst Coma: After he's dethroned, two of his close men are killed, and Mauro betrays him, he's left in a stupor for weeks, with Giovanni caring for him.
  • Anti-Villain: By the end of the series, he's still a criminal but compared to the worst Judoh has to offer, he's actually a stabilizing influence.
  • Ax-Crazy: At the beginning of the series. Prone to using violence at the drop of a hat, and particularly loves grenades (fireworks, as he calls them).
  • Badass Bookworm: Is apparently an accomplished computer hacker, among other things.
  • Berserk Button
    • Woe be to you if Clair thinks you're being someone/something you're not! There's some Irony there, as he carries more angst than he lets on
    • Also, mentioning his father. This gets Daisuke shot several times, though it was a Batman Gambit on his part as he had a bulletproof vest.
  • Big Bad Wannabe: Seems to be obsessed with looking like an all-powerful crime boss, but fails at actually being one.
  • Bishounen: Pretty, skinny, and usually decked out in feminine colors.
  • But for Me, It Was Tuesday: In the Japanese, when talking to Daisuke after figuring out Shun's plot, he says he always wakes up with a clear head. This implies that Clair considers losing consciousness, lost time, etc., even for weeks at a time to be normal (or at least not anything to be too concerned about), because he's so used to it.
  • Camp Straight: In the manga, at least, where there is a woman in his life. In the anime he has no such thing, so it's more ambiguous.
  • Character Development: Comes of age over the course of the story. Goes from an insane manchild Big Bad Wannabe to the true Vampire and leader of Judoh's criminal underground.
  • Mommy Issues: Daddy Issues, more like. He is crazy because of his abusive father. His first appearance is at his father's funeral and he doesn't know how to cope.
  • Death by Childbirth: This is what happened to his mother, assuming Lorenzo wasn't lying. Which resulted in a Lonely Rich Kid being introduced to Giovanni.
  • Death Seeker: Plays Russian Roulette and would have been killed doing so had Giovanni not showed up in the nick of time, and charges a military tank armed with only a hand grenade.
  • Dissonant Serenity: Does this on a number of occasions. The man's calm when he shouldn't be, and Laughing Mad when he should be calm.
  • Distress Ball A Corrupt Politician takes over The Mafia, forcing Clair to escape from it and go into the aforementioned Angst Coma. Then, it turns out they need his left eye to unlock a money-filled safe protected by a retinal-scan device.
  • Driven to Madness: His father's abuse resulted in a crazy kid. Character Development sets in and he gets a lot better.
  • Dual Wielding: Does this in the last episodes. (Once, even with a pair of sub-machine guns a la Master Chief!)
  • Effeminate Misogynistic Guy: He runs the only organization in the series to contain absolutely no women (unless the girls who work in the casino count), and in the manga seems to ignore his girlfriend Trinity unless he needs her expertise with robotics. And he once disparages Daisuke for having to be rescued by Kyoko because she was a woman, contrasting Daisuke who has no issue with Kiyoko's rescue.
  • Evil Laugh: Frequently breaks out into villainous laughter. Overlaps with Laughing Mad, too.
  • Eye Scream His left eye is needed to open a safe protected by a retinal scanner. He's rescued by Daisuke, who needs to keep him safe in order to (hopefully) obtain some information from him when he comes out of the Angst Coma.
  • Forgets to Eat: Gets so wrapped up in whatever he's doing that things like eating and sleeping tend to go on the back burner.
  • Good Eyes, Evil Eyes: Has "the eyes of a wild beast," according to one of the other mob leaders in Company Vita.
  • Gut Feeling: Is visibly distressed when Giovanni is sent off on a mission, seeming to know something bad is going to happen, though he can't figure out what. Giovanni gets attacked by J.
  • Hates Being Touched: Has no problem touching objects (such as hand grenades), but can't stand being touched by other people, even his best friend Giovanni. (In the manga, even his girlfriend does not make physical contact with him.) Likely due to being abused, and constantly in danger due to his "profession."
  • Heel–Face Turn: To an extent, he remains kingpin of the criminal underground, even stronger than he was before, in fact. But he's grown to be Affibly Evil and turns out there being some control over the criminal underground isn't the worst thing in the world.
  • Hellbent For Leather: Literal leather pants, dyed hair, and piercing contribute to his rebellious image.
  • Ignore The Fanservice: In the manga, Trinity wears nothing but lacy lingerie under her lab coat, and repeatedly tries to get Clair's attention. Clair is not one bit phased by her attire, and in fact barely acknowledges her unless he needs her robotic expertise.
  • Ill Boy It's mostly mental, but seems to take a toll on him physically, too.
  • Ironic Name: He's the leader of Judoh's criminal underworld and his father once announced his plans to make him a "lord of darkness" yet his name is a French word meaning "light," "bright," or "clear." Meaningful Name: However, as the series goes on, his name becomes more appropriate, as he ends up being a guiding light for most of Judoh in the final battle. Giovanni is the first to lampshade this idea ("Show Judoh that you can shine, Clair").
  • Just a Kid: Because he's only 19, the other higher-ups in the various Mafia factions don't think he'll be a good leader. At the beginning of the series,
  • Kick the Dog Most of his Evil plans have little to do with the central plot. It's revealed later that he isn't the Big Bad, Daisuke's brother is.
  • Pants-Positive Safety: Okay Clair, just keep that gun shoved in the back of your pants. Pretty impressive quickdraw, all told.
  • Psychic Powers: Has some (limited) ESP. More specifically, a psychic connection to his Heterosexual Life Partner, Giovanni. Which Clair uses to find and rescue Giovanni from a rogue J. More than likely more of a My Significance Sense Is Tingling, but given the setting, it's unclear.
  • Psychopathic Manchild: His establishing character moment is throwing a grenade at his father's funeral and babbling about "fireworks." It sets the tone quite well.
  • "The Reason You Suck" Speech He tends to give a lot of these, and gets one from Daisuke.
  • Red Baron: Vampire refers, here, not to undead bloodsucking creatures, but to the leader of the Mafia in Judoh.

Kyoko Milchan

Voiced by: Saeko Chiba (JP), Kari Wahlgren (EN)
The third and last member of the Special Service. She handles the clerical work and day-to-day stuff behind the scenes, including requisitioning and doling out Daisuke's weapon and ammunition. She's constantly flustered by Daisuke's immaturity and laziness, but still holds a great deal of affection for him.
