A very creepy fortune-teller, and also a Numbers Hunter who idolizes Kaito to an insane and stalkerish degree. Held three Numbers; No. 16: Ruler of Colours, Shock Ruler; No. 11: Big Eye; and one unnamed Number claimed by Kaito.
- Ascended Fanboy: Averted to a degree. While he is honestly a Numbers Hunter like Kaito, in the end Kaito discards him and takes his Numbers, proving how unimportant Jin really was to him.
- Cheaters Never Prosper: He uses a hidden camera to spy on the cards in Yuma's hand so that he can use cards that require him to guess cards in his opponent's hand. Cathy figures it out and destroys the cameras, then Yuma beats him.
- Femme Fatalons: Dear god, look at those things!
- Hostage for MacGuffin: Kidnaps Yuma's friends and hangs them over a lava pit to convince Yuma to Duel him with their Numbers on the line.
- Killed Offscreen: After his loss, he is confronted by Kaito, and all that is heard is his scream. Since at that point Kaito was still stealing the souls of his victims when claiming their Numbers, Jin lost his and was left as a catatonic Empty Shell.
- Master of Illusion: Which promptly proves to be an illusion. He had them standing on a foot-tall table the entire time.
Brothers and joint leaders of a gang that Shark joins after his first loss to Yuma. Yuma and Shark confront them when they attempt to steal a rare deck from a museum with the intent to leave Shark to take the fall for it. Each held a Number based on their respective fire and ice themed dinosaur decks; No. 19: Freezerdon and No. 61: Volcasaurus.
- Cheaters Never Prosper: They thought they could get away with stacking their decks. They lose anyway.
A pupil of Rokujuro and works in the Duel Lodge. At the start of the series he betrays his master and (possessed by a Number) attacks him, but he has since returned to his senses and returns to work peacefully in the Duel Lodge which he once despised. Original holder of No. 12: Crimson Shadow Armor Ninja.
- 2D Visuals, 3D Effects: Inverted; it, along with Galaxy Queen above, is one of the few non-CG Numbers.
- A Pupil of Mine Until He Turned to Evil: Was this to Rokujuro, but he's Easily Forgiven and accepted back later.
- Defeat Equals Friendship: After he loses he realizes his mistake and is welcomed back by his master in open arms.
- Ninja: Both him, his Number, and the other monsters in his deck.
A friend of the Tsukumo family and a personal friend of Kazuma. He stole No.7: Lucky Stripe from a heavily guarded facility, but it was all in order to give his niece Mayumi the necessary luck to survive a dangerous surgical procedure.
- Acquired Situational Narcissism: With a dash of Motive Decay as his "test run" of Lucky Stripe steadily escalates into a series of increasingly illegal and dangerous stunts for no other reason than because he can.
- Age-Gap Romance: He's around the age of Yuma and Akari's father, and has romantic history with Akari, who's only 20.
- Bargain with Heaven: He enters something like this inadvertently by using Number 7, sort of. A prophecy that comes with the card says that his luck will hold out until such time as the sun is split in two. No-one even knows what that means, not even Charlie (and he thinks the very idea that it's possible to destroy the sun is nonsense.) However, after Yuma destroys his "Scales of the Sun" Spell Card during their duel (its card art has a rather large sun on it) the contract is indeed broken, and his lucky streak ends.
- Catchphrase: Life is (a) Carnival!
- Chekhov's Gun: When he faces Yuma, a number of cards in his deck are ones he randomly stole from other duelists, leading him to unknowingly adding a spell that winds up being instrumental to his defeat.
- Cool Bike: Would love nothing more than to own his friend Kazuma's bike someday.
- Lucky Seven: His Number is based around this trope. Number 7: Lucky Stripe is a Rank 7 Xyz, has 700 Attack Points, and 700 Defense Points, and gives him supernatural luck.
- Papa Wolf: Towards Mayumi; protecting her is his sole motivation.
- Unresolved Sexual Tension: Between Charlie and Akari.
- Winds of Destiny, Change!: The power of his Number, making him unbelievably lucky in games and life.
Originally a modest and kind photographer and friend of Kotori, he returns during the WDC possessed by No. 25, which has given him the ability to see the future. He uses this power to take scoop photos of catastrophes that happen in the future, and becomes extremely famous and wanted among journalists because of it. Original holder of No. 25: Fullmetal Photoglide - Focus Force.
- Magical Camera: How he arranges his "scoops".
- Slasher Smile: Dear god, so very much. They're featured quite prominently during his episodes. He out-smiles all the other slasher smilers in the series so far (and given IV's record with this trope, that's saying something!)
- Self-Fulfilling Prophecy: As Astral eventually figures out, this is why his predictions always come true - he manipulates events so they happen. (In other words, Astral calls him a false prophet in nice terms.) When Yuma figures this out, he's able to defy the prophecy and defeat him.
- Villainous Breakdown: When he noticed that Yuma did not summon Utopia on the fifth turn.
- You Can't Fight Fate: Takes this attitude towards duels, as he shows his opponents images of them losing in order to lead them into doing so. This contributes to his Villainous Breakdown when Yuma rebels against his predictions."Impossible! A future beyond my imagination...I can't accept it!"
