Kaidou Jin is a prodigy with a high degree of knowledge in technology. When Jin was initially introduced he is distant from others and tends to be silent, but enjoys playing with LBX. He was also introduced as Ban Yamano's main rival and enemy. Because he was raised from the rich Kaidou family, he has a very social polite manner towards people, friends and otherwise. After becoming friends with Ban Yamano, he becomes more open.
Jin briefly appeared at the end of episode 9, eating dinner with his grandfather, Yoshimitsu Kaidou at their mansion. When his grandfather asks if he has any worries about going to school, he replies without worry, promsing to execute the plan without fail.
Jin first debuted in Episode 10, where he's seen going to school in a fighter jet, making everyone surprised at his entrance, especially by Daikoji Ryu, and makes eye contact with Ban Yamano. Later, he's seen underneath Blue Cats Cafe, battling 3 Zuul using The Emperor.

He watches Ban’s battle against Gatou, and is shocked when Ban uses his missile to implode Gatou’s missiles back at him. He makes it to the quarterfinals where he battles Ami. Ami tries to surprise him with a quick attack, but Jin anticipates it and Emperor strikes down Kunoichi in one quick hit. Jin advances to the semi-finals where he faces off against Kazu.
In episode 13, Jin and Kazu battle. Hunter tries to snipe him, but Jin’s fast movements allow Emperor to completely avoid every shot, He jumps down and strikes his mace into Hunter’s shoulder joints as he wins the match in 9.9 seconds.
In episode 14, Jin and Ban face off in the finals and he reveals to the latter that he’s a member of Innovator. Ban swears to defeat him. Ban tricks him into getting Emperor in the air and uses Advance V-Mode to gain the upper hand in battle. Jin's initial shock, is soon replaced with smiles even as Emperor’s health drops by 25 percent because in his eyes, he can fight seriously. Jin uses the Emperor at full power, further blinding Achilles with rapid fire attacks from all angles and causing Ban to lose Advance V-Mode in the process. As the fight drags on with Emperor gaining the upper hand, Jin uses the Emperor's Attack Function: Impact Kaiser to defeat Achilles. The energy and the eruption is so fierce that half of the diorama is engulfed in magma and Achilles is buried. Jin thinks he’s won but is surprised by Ban declaration of victory and Achilles getting up from the crater made from Impact Kaiser. With newfound strength, Ban is able to match him in strength and speed, and he feels generally surprised by his rival. As Achilles starts damaging Emperor, Jin's earnest happiness is shown as his butler confirms that he hasn't seen that expression from Jin in years The two are evenly matched, and him and Ban prepare their finishing moves. However, Jin’s CPU stops responding as Emperor stops before it can use Impact Kaiser. His responses were so fast that they overloaded the connection between his quick manual control and Emperor. With Emperor unable to react, Ban wins the tournament. Jin walks off, but gives Ban the coordinates to where Professor Yamano is located to help find his father. He leaves with his butler picking up his Emperor and calls his grandfather. Jin is told that he was too overconfident and tells his grandfather that he told Ban the professor's location.
In episode 16, Jin challenges Van to a rematch with his new LBX, the Emperor M2. His butler blocks off Kazu’s attempts to escape by warning them that Jin could trip the alarm if he wanted to. Jin comments on his ensured victory now that his processor’s been updated and what happened at Angra Visdas won’t happen again. When the Emperor M2 and Achilles both use their signature attack functions, they both knock out each other's LBX temporarily. Jin is shocked that he cannot seem to defeat Ban, even with a new computer processor. However, his grandfather’s henchmen come in his room to capture Ban and co, so Jin tells them to leave.

He’s revealed to be entering Artemis by himself in Block A. In episode 19, he gets through Block A easily, and faces Lex and Hanzou in the semi-finals. Jin starts the match using Impact Kaiser, but Lex’s G-Rex punches the ground of the diorama to counter his technique. Jin tries to go on the offensive, and counters Hanzou’s Gaou Cannon with the missiles from Emperor's Imperial Launcher. After surviving G-Rex’s Gatling Bullet, Jin tries to knock down Lex’s LBX but Hanzou interferes and sacrifices Hakai-O to protect G-Rex, leaving his Emperor MK 2 defenseless for G-Rex. But Jin takes a second notice when G-Rex comes close to beating him but doesn’t, so he fires Emperor’s missiles to break over G-Rex. Jin wins, but he asks Lex why he let me in. Lex answers to him that Jin was just more skilled, but Hanzou yells at him for being disrespectful that Lex didn’t give it his all. Then he easily wins the final battle and becomes the first finalist for Artemis. In episodes 20, he looks at Ban, Ami, and Kazu while smiling since he hopes to meet Ban in the battle royale.

As the fight drags on, Jin makes the Emperor M2 perform Impact Kaiser and Ban makes Achilles perform Chou Plasma Burst. Achilles manages to dodge the Impact Kaiser and give the Emperor a direct hit with the Chou Plasma Burst, causing a massive explosion in the arena. Despite this, the Emperor M2 survived the attack, but was fatally damaged. Jin realizes that if this keeps up, he would be defeated and Ban would win. Jin then uses the Emperor to hit Achilles multiple times along with sending him tumbling across the arena, near a pit of lava. The Emperor M2 then fires his missiles, only for Achilles to block it with his shield. Using its high speed, the Emperor gets near Achilles, and was able to throw Achilles' shield into the lava pit. With Achilles having nowhere left to go, Jin has the Emperor prepare to finish Achilles once and for all. While Jin declares victory, Achilles was able to hit the Emperor off guard and manages to get behind him. The Emperor fires his missiles again, but Achilles jumps in the air and lands in front of the Emperor, stabbing him with his lance and ending the fight. Jin loses, but smirks at Ban celebrating his win, because the former was impressed with his skills. Suddenly the Emperor re-activates, the eyes glowing a bright red. Jin attempted to turn off the Emperor but it was no use. The Emperor M2 grabs Achilles and self destructs, causing another massive explosion in the arena, destroying both LBX.

In episode 32, Jin fought against Jason Kurosawa, and defeats him with a single smash. In the next episode, he pair up with Kazu against Ota Pink and Ota Black, easily defeating them because of the latter pair 's long-winded speech after the battle began and Ota Pink's obsession of Jin left wide openings. In the finals, Jin's team fought against Ban's team in a 3 vs 3 match. Jin's team was able to gain the upper hand because they took advantage of Sendou's obsession of fighting Jin on solo. He was also able to figure out Sendou's trick, putting the latter at a disadvantage before being saved by Gouda that had dealt with Kazu's Fenrir with Ban. Gouda and Sendou battle against Jin's Proto Zenon together, cutting off its right arm but Jin was able to make a comeback by defeating Nightmare and Hakai OZ simultaneously with Break Geyser. With Fenrir making a comeback, his team takes on Ban's Odin, putting the latter team at major disadvantage.
However, Ban manages to find an opening and launches Gungnir to finish off Proto Zenon, Fenrir and Pandora simultaneously, allowing his team to battle against Master King. During this time, Jin acknowledges Ban's strength and claim it to be genuine.

Ban assisted him and they managed to shut it down before meeting with the former to return his Odin. Like Ban, he was also a witness to Yuusuke's death from saving Kirishima from a speeding unmanned truck.
While Ban was terrified and lost the will to continue fighting, Jin confronts his grandfather at his mansion, questioning if he had anything to do with Yuusuke's death while having Zenon doing some secret inspection on Yoshimitsu. After denying such claim, Jin makes his leave with his LBX and to his horror, discovered that his current grandfather was nothing more than an android manipulated by someone. He then told his butler regarding his decision to battle against Innovator while telling the truth to him. Jin then meet with Ban at his house, persuading him to continue fighting while telling the truth about Yoshimitsu but Ban refused, to the point he wanted to smash Odin with his own hands while blaming LBXs for causing deaths at the people getting involved with them. Jin stopped him, reminding Ban his own feelings, love for LBXs and how these machines can bring happiness to people. He claim he fully understand what Ban meant by that. After being informed that Kazu and the others are trapped in Goliath, Jin decides to go and rescue them, with a resolved Ban volunteering to follow him.

When the NICS team hears about the attack on Indonesia, Ban lets Jin go with him, Kazu, Ami, and the professor to the Innovators old base.
At the Innovator's old base, Yagami's efforts to use the original plan failed so they decide to use his secret entrance. Kazu and Ban stare in shock as he pulls a trap door in a tree branch, revealing a open wooden door. He reminds them that practical effects are still relevant as they enter the base. Using Triton to battle a few of the LBX, Jin helps secure the command center for Yagami's usage, preventing Mizel from keeping notice. He promises Ban to be safe and vice versa. As they leave, he and Yagami dicuss how the Innovator event affected them, unsure of his answer but content with his friends and seeing the world in a new light. They leave when Yagami cuts off the server room from the rest of the system. They're ambushed by Inbits but make it to the control room first.
