Billy

Biodata

Appearance

• Red jacket: His most consistently identified piece of clothing 1 3 6.
• Metal face: Has a metal chin and expressive eye sockets 27.
• Mechanical body: Includes hydraulic pistons in his legs and a hand exoskeleton 5.

Personality

Billy is talkative, theatrical, and easily frightened, often punctuating dangerous situations with jokes or exaggerated complaints. His habit of acting out dramatic scenes can interfere with combat: while delivering a speech over a fallen Ethereal, he forgets that his pistol is empty and needs Anby to rescue him 1 4 5.

He is an enthusiastic Starlight Knight fan who watches its films, follows new installments, and chooses a themed restaurant for a team celebration. He also admires Monica, the actress from the late-night drama Oh~ Sweetheart; Anby uses this interest to verify his identity inside the Hollow 3 5 7 27.

Billy worries about ammunition costs and his bonus, and the prospect of extra pay quickly boosts his enthusiasm. Nevertheless, he instinctively shields Nicole from an unknown threat and offers himself as a target when he believes she is in danger. His loyalty has complications: he suggests exposing Phaethon to Public Security during an emergency and later secretly accepts payment to question Nicole about her family 5 9 19 27.

Abilities & Skills

Dual-Pistol Marksmanship

Billy uses paired pistols to eliminate Ethereals and support close-range allies 3 4 9.

• Shoots down an Ethereal, evades an ambusher, and dispatches it in quick succession 4.
• Slides past Dullahan and shoots its knee joint, forcing it to its knees 4.
• Uses sustained gunfire to distract opponents and create openings for Anby 4.
• Must manage ammunition and reload; his pistols cannot break the reinforced bulletproof windows encountered during the Red Fang Gang confrontation 1 4.

Improvisation and Threat Assessment

Billy can recognize an unfavorable fight and use his surroundings to create an escape 4.

• Notices Bailao’s deteriorating condition and stops Anby from approaching before his Ethereal Transformation 4.
• Identifies the appearance of a core as a sign that Bailao’s transformation is nearing completion 4.
• Rejects a prolonged fight after Dullahan regenerates, then shoots nearby fire extinguishers to obscure the retreat 4.
• Steals and detonates a military flashbang during the Red Fang Gang standoff 1.

Mechanical Frame

Billy’s robotic body allows expressive movement and sustained combat, but its components can suffer strain and damage 3 5 27.

• Complains that his leg hydraulics are nearing their limit after prolonged running 5.
• Damages his hand exoskeleton while forcing open a gate with his gun stock 5.
• Remains vulnerable to Huojin’s immobilizing barrier, which stops both his movements and his guns’ cylinders 19.

Equipment / Weapons / Items

• Sister pistols — His paired firearms, used for ranged combat and covering fire 1 9.

• Phone — Uses the Knock Knock chat application to report privately to Huojin 27.

Relationships

• Nicole Demara — His employer and leader, addressed as “Boss Nicole.” Billy jokes about her spending habits but protects her when threatened. He knows that much of the agency’s money supports an orphanage and notes that she still pays their wages 3 19 26.
• Anby Demara — Coworker and regular combat partner. Their usual arrangement places Anby in front while Billy provides fire support. She rescues him from a combat mistake and frequently responds deadpan to his antics 3 4 5.
• Wise and Belle / Phaethon — Trusted Proxy partners who guide him out of the Hollow. Billy praises their reliability and is curious about their unusual sensory-link technology, although he briefly proposes reporting their identity to secure the team’s escape 5 9.
• Huojin / Hawking Hongke — Nicole’s adoptive father. Billy initially treats him as a dangerous intruder; later, he secretly works as Huojin’s paid informant, with little success 19 21 27 28.
• Nekomata — New teammate whom Billy welcomes enthusiastically. He offers to celebrate her arrival by treating the group to dinner 25 27.
• Sons of Calydon — Recipients of a shipment from Billy containing supplies and money, including a black bearer debit card 27.

Story Role / Major Arcs

Cretan Hollow and the Safe

Billy first appears fleeing the Red Fang Gang with Nicole and Anby. His attempt to shoot out a window backfires when the bullet ricochets and brings a television down on his head. He subsequently steals a flashbang, helping draw Public Security’s attention to the gang, but the resulting missile strike sends him, Anby, and the commissioned safe into the Hollow 1.

After reuniting with Anby, Billy helps locate the safe beside the mortally wounded Bailao. Bailao transforms into Dullahan, and the pair are forced to retreat when it regenerates their inflicted damage. Billy retrieves a pendant during their escape, later providing the lead needed to obtain the safe’s password 3 4 6 7.

Without a Carrot, Billy and Anby become lost until Wise reaches them through Eous. They fight toward Belle’s exit route, pass through an apparent wall, and reunite with Nicole outside 5.

On the return expedition, a hacker severs Phaethon’s connection and leaves the team following an unresponsive Eous. Billy proposes trading the Proxy’s identity for Public Security’s help, but Nicole refuses to betray their partner 7 8 9.

After Huojin and Butler secretly clear the area, Billy recovers the safe from a damaged wall. Its data chip becomes the group’s remaining escape option after the hacker deletes their route. Eous eventually leads everyone out, and Billy accompanies Nicole and Anby to Sixth Street to check on the unresponsive Wise 11 12.

Dead End Hollow and Huojin’s Arrival

Billy participates in the effort to save the residents endangered by Vision Corporation’s demolition operation. The team considers using Vision’s Ether explosives to kill the Dead End Butcher and shrink the Hollow 19.

When Huojin interrupts, Billy and Anby immediately position themselves in front of Nicole. Billy fires, but Huojin’s barrier suspends the bullets and immobilizes the group. Unable to intervene physically, Billy demands that the stranger leave Nicole alone and attack him instead 19.

Nicole confirms that Huojin is her father. Billy is further astonished to learn that he is both TOPS’s CEO and a Void Hunter 21.

Nekomata’s Welcome and the Secret Commission

Billy celebrates Nekomata’s arrival at the Cunning Hares’ base, then questions Nicole about her relationship with her father and her decision to become a Hollow Raider. Nicole explains that they get along and that she chose the work after trying other careers 25 26.

The questions are later revealed to be part of a private arrangement with Huojin. Billy reports that he cannot obtain the information Huojin wants without arousing suspicion. Huojin pays him anyway and demands secrecy, which Billy promises in the Starlight Knight’s name. Huojin subsequently judges the attempt ineffective and considers other intermediaries 27 28.
