Plot

Succession Contest arc

Members of the Xi-Yu Family boarded the Black Whale to secure territory on the New Continent. The boss is a VIP on Tier 1 of the ship. The Xi-Yu family has a direct line to their benefactor, 3rd Prince Zhang Lei Hui Guo Rou. The underlings are scheming to whittle down the numbers of their two rival families, Heil-Ly and Cha-R, until landfall. The Xi-Yu are the strongest of the three rival families in terms of finances and numbers.  They control Tier 4 and earn profits from human trafficking as well as the exchange of goods.

After a phone call with Cha-R boss Second-Track Faker Brocco Li, Onior orders his Underboss, Hinrigh Biganduffno, to find Hisoka before the Phantom Troupe. Hinrigh asks his underlings to begin their search by looking through the list of single male passengers, and look through larger families if they did not find Hisoka there. He also asks them to get the Queen to get the soldiers to do a round of ID and ticket verification. More than 300 people were killed over the next few days including underlings in both the Xi-Yu and Cha-R families, suspicions for which fall on the Heil-Ly Family.

On the 10th day of the voyage, 3rd Prince Zhang Lei pays a visit to Onior, asking Nen and Guardian Spirit Beasts to try and find a way to win the succession war. Onior mentions some of his underlings using "weird powers" and quotes "all things come to those who wait" as the strategy his half-brother King Nasubi Hui Guo Rou used to survive his own succession war. Onior offers to look into King Nasubi's battle for 3rd Prince Zhang Lei, but mentions that his investigation would take time due to conflicts in the lower tiers of the Black Whale with lots of casualties.

After 3rd Prince Zhang Lei leaves, Onior calls Hinrigh, who lets him know that the Heil-Ly were responsible for the massacre, and that the Phantom Troupe were actually helping them, not being the source of their problems. Onior questions the Phantom Troupe's true motives, whether they were just making stuff but were actually planning to find the Xi-Yu hideout, but Hinrigh confirms the Phantom Troupe's allegiances. Hinrigh reports about the killings of the Xi-Yu and Cha-R underlings and suggests the families crush the Heil-Ly before searching for Hisoka, but Onior decides not to change his plan, wanting to prioritize controlling the Phantom Troupe. After Onior confirms that Hisoka was not on Tier 4, he tells Hinrigh to give the Phantom Troupe permission to search Tier 4 as Hinrigh goes to Tier 3 to both search for Hisoka and kill Heil-Ly boss Second-Track Faker Morena Prudo.

Hinrigh takes Xi-Yu members Zakuro Custard and Lynch Fullbokko to tier 3 to search for Hisoka and crush the Heil-Ly. They see some Heil-Ly members at a nearby burger stand. A Heil-Ly woman leaves and Hinrigh follows her, letting Zakuro and Lynch deal with the Heil-Ly man. Despite him getting another Heil-Ly man as reinforcement, Zakuro and Lynch manage to defeat the Heil-Ly members and they learn about the Heil-Ly manpower and abilities with Lynch's Body and Soul. Hinrigh is forced to stop tailing the woman after she moves into the civilian area, where he learns that the Heil-Ly have listed their members as civilians, and that the Heil-Ly killing spree is for the sake of fighting instead of turf or money. Hinrigh is escorted back to Zakuro and Lynch by some Kakin military, and bribes the guards to allow them to return to Tier 4 instead of being arrested. Hinrigh uses Biohazard to kill the guards, and continues the search for Hisoka on Tier 3.

Hinrigh leaves Zakuro and Lynch to continue their search for Hisoka. Hinrigh tries to find the woman he was earlier forced to stop tailing while simultaneously luring out Heil-Ly members of Tier 3. With the assistance of a Kakin soldier, he looks through the footage of civilians on the deck and eventually finds footage the woman entering a hallway on a camcorder. He uses Biohazard to disguise the camcorder as it records the movement of people throughout the hallway, and then resumes his activities. In Area E, Hinrigh is found by Heil-Ly members Padaille, Quorolle, and Tevelares, who confront him. Padaille is killed and Quorolle and Tevelares decide to escape. Heil-Ly member Misha Hao appears to take control of Padaille's corpse and help manage the commotion by pretending that Padaille's injuries were not as serious as they were, before taking his corpse away to be disposed of. One of the Kakin soldiers, Corporal Maizan, approaches Hinrigh during the aftermath of his conflict, and offers information on the location of Morena Prudo to him. After confirming the source of the information, Hinrigh agrees to pay 50 million Jennys for the information with 30 million Jennys in advance on condition that Corporal Maizan personally escort him there. Corporal Maizan agrees and disperses the crowd, resolving the situation.

Zakuro and Lynch resume their search of Hisoka and eventually find him. Lynch approaches Hisoka, intending to use Body and Soul on him to confirm his identity, but Hisoka reflexively knocks her out before she can use her abilities. Overwhelmed by Hisoka's aura, Zakuro offers to bring Hisoka to the mafia to explain why they were looking for him, but Hisoka tells Zakuro that he's going to the cinema before knocking him out. Hinrigh goes to the Cinema, lead by Zakuro after recovering from Hisoka's attack. Hinrigh approaches Hisoka and asks him to keep to Tier 1 to keep him away from the Phantom Troupe so they can continue helping them with the Heil-Ly, offering Hisoka a room in the VVIP area of Tier 1. Hisoka asks Hinrigh about who he thinks would win in a battle between Hisoka and the Phantom Troupe. Hinrigh gives an honest answer, that he believes the spiders would win. Hisoka accepts Hinrigh's offer, but warns that he will not back down if the Phantom Troupe finds him and decides to pick a fight.

Xi-Yu Lieutenant Connelly brings the money to Corporal Maizan and finds Cha-R underboss Ken'i Wang there with several Cha-R underlings. Hinrigh rejoins them, and the Corporal brings them to Room 3101, where he reveals the existence of a hidden section. Hinrigh asks the Corporal to turn his gun safety off in case of a conflict. The door to Room 3101 is opened, revealing an old man. The Corporal steps in, but vanishes, surprising Hinrigh and Ken'i. The man invites them into the room, but Hinrigh, suspecting something is amiss, throws a knife at the old man instead, which does not vanish. The man makes his way to the bathroom, feigning a need to use it, but Hinrigh throws a knife at his leg. He questions why the man does not bleed despite his leg being pierced by a knife, and the man vanishes into aura, leaving the knife behind. As Hinrigh and Ken'i discuss how best to proceed, Xi-Yu underling Tassi runs into the room to pick up Hinrigh's knife but vanishes, confirming Hinrigh's suspicion of a trap. Ken'i suggests leaving the trap to the Phantom Troupe to investigate and leaves, and Hinrigh decides to leave as well and follow up on his own leads in the meantime.

Hinrigh returns back to the camcorder and looks through the footage, noting that several Heil-Ly members passed through one direction twice, indicating the presence of a secret passageway. He reconvenes with Ken'i and several members of the Kakin military to share information. He learns that the Phantom Troupe plans to head to Room 3101 and engage the trap directly, returns to the room with Ken'i who would introduce him to the Phantom Troupe, and suggests a plan to the Phantom Troupe. Hinrigh uses his Biohazard to turn a location tracker into an oyster, which he swallows before stepping into Room 3101's trap and is teleported into the Heil-Ly secret hideout.

Hinrigh sees an empty, recently abandoned room when he first enters. Shortly after, he sees Nobunaga follow him into the trap, and the two explore the base together. Hinrigh opens the door to reveal eight Heil-Ly members sitting at a table. Wary of another doorway trap, Hinrigh calls out to them from the doorway. They ignore him, and so Hinrigh throws a knife at the head of the nearest member, who uses his ability to transfer the damage. Heil-Ly member Yokotani introduces himself as part of the conditions to activate his ability, and then uses LSDF to conjures puppets which forcibly drag Nobunaga into the doorway, teleporting him out of the base. Hinrigh runs away from the puppets, and hides the tracker in the Heil-Ly base before himself being forced out through the doorway. Having used up his resources for the day, Hinrigh decides to switch to a support role for the rest of the day and lets the Phantom Troupe continue the search for the transmitter and the Heil-Ly base.

• The crest bears a resemblance to the kanji for "to surround" (周), which can be pronounced like the first part of the family's name ("shū").
  • It is also the kanji used for the homophonous Nen technique.
