Assault is a male member of the White Clad organization, previously part of the elite Destroyers assassination faction. He possesses formidable combat skills, earning him titles like "Bloody Fire Blast," "Assassin from the Abyss," and "Perfect Soldier" for his ruthless efficiency and annihilation proficiency. He stands 182 cm tall, weighs 80 kg, and has dark skin with light spiky hair. Distinctive features include three piercings in each ear and two piercings replacing his absent eyebrows. He wears a White Clad uniform variant, marked by white clothing and the Sol God cross symbol on his chest. As a Third Generation pyrokinetic, Assault generates and manipulates flames using his Ignition Ability, Crimson Bullet. This technique creates condensed fire missiles around his limbs that detonate on impact, inflicting severe damage and propelling targets airborne. His combat prowess allows him to single-handedly defeat Demon Infernals and effortlessly block advanced Ignition Abilities, such as neutralizing Arrow's projectile attacks with a finger. These capabilities established assessments that he could annihilate Special Fire Force Company 8 alone. Personality-wise, Assault presents as a stoic professional dedicated to the White Clad's objectives. He expresses discomfort with killing women and children, preferring to grant them quick deaths. A defining trait is his acute shyness around young women, particularly when confronted with revealing attire or accidental nudity, which often disrupts his focus in battle. He engages in rigorous self-improvement regimens to overcome this weakness, analyzing pornography and seeking exposure therapy through conversations with women. Despite confidence in his training methodologies, he acknowledges emotional responses like attraction or embarrassment as variables he cannot fully control. His narrative involvement centers on recurring confrontations with Tamaki Kotatsu of Company 8. During their initial Netherworld encounter, Assault corners Tamaki and Iris, exploiting his combat superiority. However, Tamaki's "Lucky Lecher Lure" syndrome causes her undergarments to detach mid-fight. This distraction allows Iris to strike Assault with a metal pole, leading to his defeat. Seeking redemption, Assault undertakes specialized training to resist Tamaki's influence, including studying adult material and desensitization exercises. Subsequent rematches consistently fail, as Tamaki's genuine embarrassment proves more disarming than deliberate seduction. After a third loss, Assault observes a civilian woman's accidental exposure during a windstorm, concluding his training remains inadequate. He privately admits an inability to defeat Tamaki, attributing it to unrecognized romantic feelings for her. Months later, during the Second Great Cataclysm, Assault intervenes when a doppelgänger mimicking his appearance attacks Tamaki. The entity condemns Assault for tarnishing his reputation through "worldly desires" and failures, declaring itself the true embodiment of his legacy by rejecting human emotions. Assault counters that desire is integral to existence and embraces this aspect of himself. Mid-argument, Tamaki's torn clothing exposes her skin, causing Assault to falter. The doppelgänger capitalizes on this distraction, criticizing his "lust" as a distortion of truth. This confrontation underscores Assault's acceptance of his vulnerabilities as part of his identity. Background details include his self-identified persona ("I am I"), preferences for cats, black and yellow colors, and admiration for untrained individuals. He dislikes those opposing the Empire and "people who take over at a hotpot meal." Daily routines emphasize relentless training, with hobbies centered on self-improvement. His dream involves witnessing the world that emerges once his training reaches completion.
