Movie
Description
Takumu Mayuzumi shares a deep history as the childhood friend of both Haruyuki Arita and Chiyuri Kurashima. His record of perfect academic standing and kendo tournament victories stemmed from exploiting the accelerated perception granted by the Brain Burst program. This point-draining strategy ultimately led to his expulsion from the Blue Legion Leonids faction commanded by Blue Knight.
Driven by romantic feelings for Chiyuri and resentment over her focus on Haruyuki, Takumu implanted an illicit surveillance program into Chiyuri's Neuro Linker. This backdoor revealed Kuroyukihime's hidden identity as the Black King. Desperate to regain lost points, he challenged her, inadvertently prompting her decision to grant Brain Burst to Haruyuki. Their escalating conflict reached a physical confrontation where Takumu voiced his bitterness toward Haruyuki before achieving reconciliation. Committing fully to Kuroyukihime's legion, Nega Nebulus, he transferred to Haruyuki's school. Takumu symbolically chose prescription glasses over Neurolinker vision correction, resolving to "see the world with his own eyes."
His duel avatar, Cyan Pile, physically embodies his internal struggles. The armored, knightly form represents his aspiration as a swordsman, while its primary weapon, the Pile Driver—a spear cannon deploying a retractable metal spike—originates from a deep-seated fear of thrusting attacks, a trauma rooted in childhood bullying. Key abilities include:
- **Splash Stinger**: Firing multiple spikes from his chest panel.
- **Spiral Gravity Driver**: Transforming the Pile Driver into a drill capable of breaching barriers.
- **Lightning Cyan Spike**: Launching a spike projectile enhanced by plasma energy.
Subsequent training unlocked his Incarnate ability, **Cyan Blade**, materializing a sword from the Pile Driver's spike that can sever physically immune objects.
Later, the Player Killer group "Supernova Remnant," contracted to target Silver Crow, assaulted Takumu. Forced into a "Sudden Death Duel," he accepted an ISS Kit from Magenta Scissor for survival. The kit granted power at the cost of corrosive nightmares and emotional manipulation, manifesting as a dark eye within his Pile Driver. Under its influence, he confronted Haruyuki aggressively. When the kit attempted to infect Silver Crow during their duel, Takumu deliberately impaled his own avatar's neck with Lightning Cyan Spike to halt the corruption. Later, during a direct-link sleepover vigil at Chiyuri's home, he confronted and destroyed the ISS Kit's core manifestation within the Brain Burst central server using Cyan Blade, achieving full purification.
During the "Infinite Burst" storyline, Takumu fought alongside Sky Raker and Ardor Maiden in a territory battle between Nega Nebulus and the Great Wall legion. This conflict was abruptly terminated when a massive storm engulfed the Accelerated World, disabling Brain Burst globally.
