Set in the year 2046, Neuro-Synchronization allows humans to virtually manipulate their five senses, where people can access the internet and enter virtual worlds via Neuro-Linkers. The series follows Haruyuki "Haru" Arita, a short, fat boy who has low self-esteem due to being bullied at school which Haru vents his frustrations in virtual world games.

But in order to gain more points to accelerate, Brain Burst users fight each other in a virtual reality massive multiplayer online (VRMMO) fighting game where losing all of your points means you can never use Brain Burst again. Grateful for helping him, Haruyuki vows to help Kuroyukihime defeat the "Six Kings of Color", the leaders of the most powerful factions in Brain Burst and obtain Level 10 to ultimately learn why the "Accelerated World" was created.

To vent his frustration, he resorts to playing squash in the school's virtual world network where he always gets the highest scores. Haruyuki's childhood friend, Chiyuri Kurashima offers to have lunch and suggests that he report the delinquents to the school board, but he rejects her pity, knocking her lunch basket to the ground. Later, on returning to play squash, he discovers that his highest score was beaten by Kuroyukihime, the Student Council Vice-President, who invites him to lunch the following day. Haruyuki meets with Kuroyukihime, who offers to cable with him, shocking the other upperclassmen. She then transfers a program called Brain Burst to him. After it successfully installs, Araya shows up and Kuroyukihime provokes him into punching Haruyuki at which point she shows him how to activate the potential of Brain Burst, virtually accelerating their cognitive processes to the point at which time around them seems to stop. While in the accelerated mode, Kuroyukihime advises Haruyuki to let Araya's punch connect with him, knocking himself at her so that the school's cameras and nearby witnesses will catch Araya violently attacking them, ending Haruyuki's ridicule. Haruyuki complies which ends with Araya and his gang being detained by security.

Kuroyukihime tells Chiyuri that she is dating Haru and drags him to a cafe. While there, Kuroyukihime explains her dilemma to Haru. Brain Burst was anonymously created seven years ago which allows acceleration only to those who were born with the neuro-linker. Therefore, all Burst Linkers are children age 15 and younger, allowing its existence to be concealed from the public. Kuroyukihime wants to meet the creator to learn the purpose of the program. To do that, she needs to reach level 10, which requires five wins over level 9 Burst Linkers and one defeat results in the permanent uninstallation of Brain Burst. Two years ago, Kuroyukihime was one of the Kings of Pure Color, a group of level 9 Burst Linkers that agreed to not fight each other, but she did not agree to the treaty and beheaded the Red King, causing her to be branded a traitor and leading her to seal away Black Lotus. Since then, she has stayed offline, only logging on to the school's local net with a dummy avatar. Recently, she was challenged to a duel by a Burst Linker named Cyan Pile, which could lead to her identity as Black Lotus being exposed. Thus, she must find Cyan Pile's identity. She suspects Chiyuri, which is why she provoked her, although Haru doubts it knowing that Chiyuri is bad at games. Haru begins the investigation by going to Chiyuri's home under the pretense of apologizing for lunch the other day. The two link up with each other with an extremely short cable and reconcile with each other, with Chiyuri letting Haru know that Takumu was not told about the ridicule. During the conversation, Haru discovers that while Chiyuri is not Cyan Pile, there is a back door connection that could lead to finding its identity.

As Kuroyukihime and Haru walk together that day, Haru resigns himself to just being a pawn, prompting a slap from her. Just then, an out of control car (driven by a mad Araya) heads straight towards Haru and Kuroyukihime, prompting them to go into the Accel World. As Kuroyukihime confesses to Haru that she is in love with him, she uses a powerful move called Physical Full Burst, which causes her to lose nearly all of her Burst Points, allowing her to manipulate her body in the Accelerated World to push Haru out of the way of the car, leading to only her being hit. As Kuroyukihime is taken into intensive care, Haru comes to realize that if she was to be attacked by a Burst Linker now, she would be completely vulnerable, and so chooses to stay the night.

Haru finds himself in a basement where he finds Kuroyukihime's sleeping avatar, whose beating heart reminds him how strength isn't always about winning.

Based on the swiping gesture Rust Jigsaw made whilst not wearing a Neuro-Linker Haruyuki deduces that their faction is using illegal Brain Implant Chips which they connect to networks with and only use their Neuro-Linkers just as they enter a duel thus masking them from the matching list. The next day, Haruyuki confronts Seiji with his discovery and they agree on an ultimatum: settling their score with a final duel in the Unlimited Field where the winner claims all of the losers Burst Points. Haruyuki, with Takumu supporting him, determines to end their plight before Kuroyukihime returns.

As the day of the duel arrives, Chiyuri asks to join Haruyuki and Takumu in the Unlimited Field. Choosing to believe in her, they comply. Silver Crow, Cyan Pile and Lime Bell approach the battle ground, the school's sporting field, where they encounter Dusk Taker and begin the duel using a Sudden Death Duel Card. As the battle begins, a new Burst Linker, Black Vice ambushes them and immobilizes Silver Crow. Taker explains that Vice possess a Deceleration ability via his Brain Implant Chip. Taker then battles Cyan Pile who manifests his incarnation ability, Cyan Blade, and overcomes Taker's Demonic Possession due to Taker already having too many abilities, and slices off an arm. Dusk Taker explains that he was bullied by his older brother who was also his Brain Burst parent, forcing him to obtain points for him. This drove him taking revenge on his brother by repeatedly killing him within the Unlimited Field and stripping him of Brain Burst. Taker then takes Lime Bell hostage and tortures her, explaining that the bonds they have are illusions. This proves too much for Cyan Pile, causing him to lose focus, giving Taker an advantage and cuts off both his arms. As Haruyuki laments on the hopelessness of the situation, he loses the will to fight. But he eventually regains his resolve from his avatar (Silver Crow) and his memory of Kuroyukihime. He manages to overpower Black Vice, at the cost of his metallic armor, and surprises Dusk Taker but instead falls to the ground. Just as all hope seems to truly be lost, Dusk Taker is stopped from finishing off Cyan Pile by Black Lotus, who appears on a level 15 Enemy using the reins obtained from Crimson Kingbolt. As Taker is taken aback by her arrival, Black Vice introduces themselves officially, as being a part of the Acceleration Research Society (which Sulfur Pot was also a part of). Black Lotus then deems them her enemies for trampling on her Legion members and fiercely attacks Black Vice while encouraging Silver Crow to stand and face Dusk Taker once and for all.
24	"Reincarnation" Transliteration: "Saisei" (Japanese: 再生)	September 22, 2012 (2012-09-22)	September 27, 2013
Realizing that they won't be able to understand each other's ideals, Dusk Taker takes to the skies followed by Silver Crow upon equipping the Gale Thruster. As their aerial battle commences, Crow manages to strike Taker as the Thruster's SP gauge runs out but is able to recharge it quickly using incarnation and deal Taker a powerful strike. At that moment, Lime Bell uses Citron Call, with the wave enveloping both Crow and Taker. In a dramatic turn of events Taker is healed but, the wings return to Silver Crow. As Taker begins to fall, the wings merge with the Gale Thruster enabling Crow unlimited rapid air-speed which he further combines with his Laser Sword to deliver a final devastating blow to Dusk Taker. After the battle, Lime Bell reveals that her ability isn't healing but in fact, Time Reversal, which she used on Dusk Taker to revert him back to the state in which he didn't possess Crow's wings. She also reveals that she only stuck with Taker so that she could level up and wait for the right moment to use her ability. Reduced to nothing more than his torso, Taker begins pleading with the Black Legion and even Black Vice to spare him, or else he would reveal all of their information and the Acceleration Research Legion to the real world. Vice declines to help him and instead retreats, having no grudge against them and that Seiji's Brain Implant Chip would dissolve after Brain Burst is removed, tying up the loose ends. After Silver Crow delivers the final blow, Lime Bell reveals she informed Black Lotus of the events prior to their battle and officially joins Nega Nebulus. Back in the real world, as Kuroyukihime returns, Haruyuki gives her the full story and she tearfully embraces him, worried that she might have lost him and vows to stay by his side. She also clears Haruyuki's name at school whilst Seiji lost all memories pertaining to Brain Burst. After school the group along with Yuniko and Blood Leopard theorize about Brain Burst's effects on a person's memories after it is removed, concluding that they should reach Level 10 and ask its creator directly. Finally Kuroyukihime accompanies Haruyuki as he keeps true to his promise of returning Sky Raker's armament to her. Kuroyukihime tearfully calls out to Raker as she leaves wanting to repair their friendship and they run and embrace each other. At this point, they refer to each other by name, Sky Raker being Fuuko Kurasaki and Kuroyukihime being "Sac-chan". Haruyuki concludes by saying that no matter what difficulties and changes lie ahead, humans will continue to accelerate forward.
