Momoya Agakura

Momoya Agakura (阿牙倉 百矢 Agakura Momoya) is a member of the Agakura Clan whom Kuon Higuro has hired to be on 'his side'.

Appearance
Momoya is abnormally tall, about 230 cm, and possesses abnormally keen eyesight. His main outfit consists of a black-and-white jacket over a black-and-yellow striped shirt, a large belt, sneakers, and black skirt-like physical restraint that cuts off at his shins.

Personality
Momoya is highly bloodthirsty individual. He lives solely to experience thrill of combat and killing. His thirst for blood makes him nearly fearless, even when facing supernatural phenomenons.

Chronology
Nearly ten years before Corpse God's reincarnation as Polka Shinoyama, Momoya and his older sisters Kana and Majiri Agakura slaughter a group of small-time terrorists in a certain building. Shortly after that, Xiaoyu Lei—a child assassin of the Heilei, arrives to carry out his first mission: kill everyone in the building. Xiaoyu tries to cut Majiri's throat, only for Majiri to cut off his arms and legs, which she promises to return if Xiaoyu someday agrees to join Agakura.

Present
Sometime after the Corpse God's reincarnation, Momoya and 'the girls' of Agakura carry out a mission to dispatch a group of armed individuals planning an aboveground-underground attack on a station. While 'the girls' handle the group's main unit aboveground, Momoya single-handedly kills the underground 'distraction unit' before the unit's attack so much as commences; a minute later, an individual contacts him via walkie-talkie to request a status update. With Momoya's job confirmed done, the individual immediately assigns him a new, short-notice one: to 'pay a visit' to the Mediators in Shibuya.

Momoya and Kuon Higuro, a man who has hired Agakura for his own purposes, thus travel to Shinjuku without delay. As they wend their way through Shinjuku's streets, Momoya spots Xiaoyu in the far, far distance and comes to a stop. He recovers once Higuro reminds him to keep a low profile in Lisa Kuraki's territory and admits he is impressed that Xiaoyu managed to survive their past encounter.

Later that day, Higuro, Momoya, or an ally places a strange phone call to Nishida—one of Clarissa's Youtoukorou employees—likely to lure him away from work and to a discreet location. At that location, Momoya decapitates Nishida. Once night falls and the moon shines overhead, Momoya and Higuro are set to work: Momoya tucks Nishida's corpse into a duffel bag he hefts to carry. At the same time, Higuro unlocks the door to a stairwell and passageway. Momoya follows him inside while questioning whether they are or are not accessing the building Phantom Solitaire visited yesterday, and Higuro explains that they are; however, since that building is under surveillance, they will have to surreptitiously use this building's passageway to carry the corpse there via the basement passageway.

As the two descend the stairwell, they encounter a trio of men loitering on one of the stairs platforms. One of the men procures a knife and 'suggests' that the duo "donate to their cause." When Higuro fails to immediately acknowledge the demand, the stockiest man grabs him and punches him in his cheek; unfazed, Higuro expounds on his belief that "connections are love" for a little while before shooting a bullet sideways through the man's mouth. He shoots the other two men in their chests, reshoots the stocky man in his back while he doubles over, and explains that they are about to die because they lack connections before shooting them dead.

Momoya laughs that Higuro is wasting his bullets as they resume their descent—taking care to step around the blood—though he concludes that the fact a 'lowlife' life Higuro is walking the streets must mean he was right about the world ending. The two can reach the target building's basement and deposit Nishida's headless corpse without problems.

The morning of the next day finds Higuro and Momoya stationed in a building near the target building (the abandoned torture building), which they are spying on from a window. As a team of police park and enter the torture building, Momoya idly hopes that "this time" they will be able to find the body easily.

Two plainclothes policemen arrive as well—Tsubaki Iwanome and Kōzaburō Arase—and Higuro pales the instant he spots Arase through his binoculars, explaining to Momoya that Arase is the detective who destroyed his previous gang Sons of the Styx. Arase's unexpected involvement is enough for Higuro to conclude he cannot rely solely on what "information that came down from above," logic with which Momoya agrees even if he enjoys it when situations go awry; Higuro further supposes he should find out whatever he can himself, mentioning that his former informant is now working with a 'business rival'—i.e., Clarissa—in Shinjuku.

Momoya's focus shifts from Higuro to a confrontation playing out on the streets below, one between Xiaoyu and Heilei member Taipei, which is interrupted when Misaki Sakimiya cannily drags Xiaoyu away. Through observation alone, Momoya pegs Misaki not only as a killer, but as a killer who has likely killed at least ten people already. Higuro uses his binoculars to look—just in time to see her reconvene with his former informant Takumi Kuruya. Eyes wide, he posits that the girl is likely one of Clarissa's assassins.

Momoya muses over all the players involved so far: Polka, accompanied by an assassin and an informant; members of the Lei Family; a building visited by Phantom Solitaire; and Detective Arase—and he happily predicts this job will be far more fun than he thought it would be.

When the police finally leave the premises, they do so without urgency and without making any arrests—a sure sign that Nishida's corpse somehow remained undetected during the premises search. Higuro seeks answers.

That evening, Momoya breaks into Takumi's empty apartment and waits in the shadows for Takumi to arrive home. Rather than confront Takumi immediately, he holds off until Higuro rings Takumi's flat; as Takumi backs away from his intercom, Momoya then reveals himself by suggesting that Takumi let Higuro inside—only to do the honors by pressing his weapon against the unlock panel with enough force to make the panel crack.

Once Higuro joins them in Takumi's flat, and Takumi's arms and legs are bound together, Momoya stands back to let Higuro interrogate his former comrade. Higuro stabbed two pens into Takumi's left thigh before asking him how his people managed to hide the body, explaining that his employer needs the police to find the corpse in the building and make everyone associated with that building suspects; now that Takumi has heard all this, he adds, Takumi must know he is out of options.

Momoya, registering movement outside the several-stories-high window, remarks Takumi may still have options after all. Misaki smashes a hole through the window with her crowbar a moment later and launches herself at him. Momoya blocks her crowbar swing with his blade and is shocked to find her strength is superior given the difference in their bodies; despite this, he manages to block her next swing. He is again surprised when she jumps over him—the first person to ever do so—but slices his blade clean through her torso while she is airborne, cleaving her in twain.

With blood from a temple cut trickling down his face, he opines their alteration was a close call.

Higuro injects Takumi with a drug that causes him to pass out and telephones a superior to report the 'hiccup' while Momoya packs Takumi's body into his duffel bag. They leave Misaki's bifurcated corpse behind in the flat before descending to where they have parked a black van. They speed off down a major street with Momoya and the duffel bag in the back and Higuro behind the wheel.

Someone slams onto the van's roof, and Momoya stabs his blade through the ceiling while Higuro swerves down a side road to throw the attacker—Misaki—off the van. Upon reaching their hideout, Momoya strips Takumi of his outer shirt and is unimpressed to find a criminal like Takumi carries no weapons. However, realizing that Takumi may possess a transmitter instead, he quickly suggests they break Takumi's cell phone. Higuro permits him to do it once only after he (Higuro) can examine the phone's data.

Not entirely satisfied, Momoya rolls Takumi onto his back and asks if his headset visor might have an embedded transmitter or radio. Higuro supposes it probably does, but their hideout's radio wave-jamming capabilities should render the possibility moot—and his and Momoya's own cell phones moot, for that matter. Momoya briefly considers the trouble he will be in if 'the girls' try to contact him but accepts whatever trouble may come.

Once Takumi is awake, he is surprised to learn that Momoya is an Agakura; not only is Agakura's reputation well known in the underworld, but Higuro used to warn him against engaging with Agakura at all costs. Higuro affirms this to be the case—and that he subsequently hired Agakura's men to be on his side, just as Takumi did with the Heilei. In Takumi's sincere bewilderment, Higuro tells him that Xiaoyu is an assassin employed by the Shinoyamas.

He resumes interrogating Takumi with a little torture thrown in; when he implies Sayo Shinoyama and her family might be threatened next should Takumi die, Xiaoyu—perched on an overhead beam—decides to interfere. When his subsequent fight with Momoya seems poised to end the same way Misaki did—with Xiaoyu cleaved in half—Misaki saves Xiaoyu's life. However, Misaki's survival shocks both Higuro and Momoya; Momoya chooses to take the fight seriously rather than back down finally.

As Momoya and Misaki face off, with Xiaoyu, a secondary combatant, Misaki unabashedly uses her newfound abilities as a Vampire Larva to her advantage; Momoya suffers a serious cut to his abdomen when she wields the crowbar by separating her hands from her body. Misaki soon baits Momoya into grabbing her, allowing Xiaoyu to deliver Momoya several critical blows: Xiaoyu pierces Momoya's body with four extended digits—piercing his left thigh, his torso twice, and his right shoulder—and then electrifies Momoya via multiple currents.

Momoya collapses. By the time or after he comes to his senses, his sisters Kana, Dahlia, and Majiri have come to his rescue—Majiri having severed Xiaoyu's right forearm by the greeting. Majiri and Misaki trade a blow or two, but any prospect of a quarrel vanishes once Momoya coughs up blood. Realizing their younger brother is in mortal peril, the three sisters successfully retrieve him and leave the premises.
