Taro Sakamoto, Yoichi Nagumo and Rion Akao vs Kindaka is a battle fought by JCC students Taro Sakamoto, Yoichi Nagumo and Rion Akao against Kindaka.
Prologue[]
The trio, consisting of Taro Sakamoto, Yoichi Nagumo, and Rion Akao, along with Uzuki, who have been expelled cause of their reckless and troublemaker behaviour, get a chance to redeem themselves by completing an off-campus mission with the objective of assassinating a specific target, Kindaka. After a bit, the trio finds themselves at the entrance of the JCC, where they first obtain the JCC card or assassin license, which allows them to leave the campus and do off-campus assignments.
While the trio was heading towards the objective of the assignment, they are introduced by the vice principal to Uzuki, whom the vice principal describes as a third-year student from the assassination department, just like them. Rion immediately goes to greet him with a friendly approach, but Uzuki silently brushes her off and remains quiet. Later on, they all manage to reach the objective. Later on, they all manage to reach the objective location. The trio, along with Uzuki, enters the shop where they immediately engage in silent and quick fights with all the assassins disguised as customers and those hidden in the clothes. Rion swiftly dispatches them, killing all of them while also interrogating some of them and acting kindly and friendly towards the civilians.
Battle[]
Nagumo and Sakamoto do the same as Rion until they are interrupted by the arrival of a man who reveals himself to be the steel dragon and a current member of the known organization called the Order. The man asks who is the strongest between the two, and both Nagumo and Sakamoto confirm that it's Sakamoto. The man proceeds to introduce himself as Kindaka. The two immediately rush at the man to attack him, but Kindaka effortlessly disappears from their sight and blitzes them by hitting both their faces, instantly appearing behind them. When they realize this, they both turn around, only for Kindaka to appear behind them again. Both Sakamoto and Nagumo attempt to stab him with their knives, but Kindaka kneels himself and disappears again, reappearing a few meters from them with a relaxed and calm attitude.
He explains to the two students that his speed is thanks to his shoes and then states that their teacher, Etsuko Satoda, told him about them. Meanwhile, Rion is arguing with Uzuki, who tells her that killing is wrong. She mocks him, asking why he would join an assassin school if he hates killing. While the two are talking, Sakamoto suddenly gets thrown out of the floor, falling down in the middle of the mall until Kindaka appears behind him while mid-air and grabs Sakamoto's shirt, throwing him through multiple iron ladders. Kindaka stops for a second, noticing Rion's gaze upon him from the higher floor, which he notices and proceeds to engage in a fight with her.
Rion manages to hit him, which makes Kindaka wonder what does the girl sees with her eyes. Rion interrupts his thoughts by throwing a freezer into Kindaka's head to blind him. Once caught, both Sakamoto and Nagumo appear, kicking the iron box and smashing it with their kicks, crashing Kindaka inside and managing to hurt him, leaving him with multiple wounds on his face. Kindaka stretches himself, which makes Nagumo wonder how he is still standing after sustaining such damage. Kindaka asks the trio if they would like to join the Order but stops them, saying to answer him after he had beaten them up. The trio attacks Kindaka again, but in a mad dash, he appears in front of Nagumo who attempts to jump to dodge Kindaka's attack, but he grabs Nagumo's ankle mid-air. Nagumo responds by throwing a kick at Kindaka, who dodges by lowering his head.
Meanwhile, Rion throws a knife to Nagumo, which he grabs and uses in an attempt to stab Kindaka. However, Kindaka suddenly throws Nagumo out of the floor, sending him crashing onto a pair of floors below into a mattress shop, heavily injuring him. Nagumo takes the chance to rest on one of the exposed beds in front of one of the shop assistants. Meanwhile, Kindaka throws Nagumo's knife at Rion, who dodges and retaliates with a kick. Kindaka evades the kick by crouching down and then disappears in the middle of a grocery store. Rion quickly turns around, attempting to slash behind her, but she instead finds a bottle of alcohol Kindaka placed, which she accidentally slices, causing it to splash into her eyes and temporarily blind her, disabling the special sight Kindaka was interested in.
Kindaka smiles at Rion's pain but gets interrupted by Sakamoto appearing from behind him. Sakamoto proceeds to throw Kindaka inside an elevator, sealing himself inside with him and stating that in a confined space, speed doesn't matter. Kindaka is intrigued and tells him to try. Kindaka starts to spin around Sakamoto at a massive speed, even utilizing the elevator's walls, but Sakamoto stops him with a backward punch, smashing Kindaka's nose. Kindaka then shifts his shoes into maximum gear. Kindaka increases his speed massively, rushing through the mall at an incredible pace, attempting to confuse Sakamoto. He almost collides with Uzuki, but manages to dodge him at the last moment, stopping himself and clutching his back in pain from the sudden stop.
Meanwhile, Rion has just recovered from the alcohol in her eyes, wiping them with her finger and asking Uzuki if he saw Kindaka, which he denies. He states that following a fast target with your eyes is impossible; you have to anticipate their moves based on the surroundings. Rion laughs at his answer. While Kindaka is still recovering, Sakamoto seizes the chance to wrap a long banner around him and starts spinning him around, gaining speed until he brutally crashes Kindaka through multiple floors of the mall, ending their fight.
Aftermath[]
After successfully defeating Kindaka, the trio lets out a sigh of relief, thinking they've avoided expulsion. However, Kindaka quickly denies their claim by stating they would have been expelled regardless of the outcome. He explains that every student sent on the mission against him is essentially sent to their death, and if anyone manages to survive, he offers them a spot in the Order. The trio looks shocked and confused as Nagumo takes out his phone and calls the JCC, which promptly confirms Kindaka's words and commends the trio for surviving a mission known for its impossible chance of success. Despite their confusion, Kindaka reassures them by saying he could get them back into school, but he wants to make a deal first. Since their fight hurt Kindaka's back, he proposes that the trio, along with Uzuki, accompany him on a mission to escort the chairman of the JAA to safety. The trio accepts the deal.
