Sick Arc

The Sick Arc is the fifteenth arc of the Undead Unluck manga series. It deals with the recruitment of Rip and Latla by saving Leila from a Master Rule UMA known as Sick.

Synopsis
Most of the Union and their family, including Bau, enter the Roundtable to fast forward to the next Negators. However, Isshin the 12th stays behind due to wanting to see his granddaughter grow up, passing on during the time skip. Afterwards, Fuuko heads to Paris to meat with Latla, who they had met previously during Fuuko's travels and had tasked the fortune teller to hone her skills to become a vessel for her Negator abilities, and to see if Rip had done the same as well.

The 101st version of Rip, having mastered his skills as a doctor, heads to Iseult Hospital to check up on Leila, and later proposes to her. When she along with several other patients suddenly become deathly ill, Fuuko appears and reveals that the source is a powerful UMA known as a "Master Rule". After saving all the patients with his medical skills, he finally talks with Fuuko and later learns the only way to save everyone is to give up being a doctor and awaken Unrepair, with his legs being amputated so he can use the Blade Runner Artifacts. After having a day to himself and the Mirah sisters, he resolves himself to save everyone, prepared to become a Negator and give up being a doctor.

When the next wave of Sick hits the hospital, the trio comes back, but Leila is put in critical condition due to close proximity to Sick's effects. Upon arriving, Fuuko tells Rip to take Leila to the operating room, holding back Sick, who had appeared in person. Just before Rip can start the procedure, Unrepair awakens in him, but is stopped from touching her with his powers thanks to Sean and Chikara being there while the rest of the Union appears to back up Fuuko and take down Sick.

Because of Sick's status as a Master Rule, defeating them seems impossible thanks to their regeneration, and infects several of the members while pinning down the rest. Rip and Latla appear, and its shown that they have shared the artifact by having one of their legs amputated to fight the UMA as Fuuko operates on Liela to save her as well as bait the Master Rule. Despite Sick managing to play smart by turning off the lights, Latla's ability, revealed as "Untrust", redirects the attacks, as the infected doctors manage to help in pinning down Sick so they can be bisected by the upgraded Blade Runner's attack. However, Sick makes Fuuko accidentally evoke her Unluck and cause a meteorite to fall on the hospital. As Fuuko orders everyone to protect the civilians, a hand suddenly appears and reforms into Andy, it being a clone sent by the original him to help turn the tide. However, Move helps Sick escape because Undead makes the fight against Sick "too boring". After Sick is repealed and Liela is saved, the Andy clone sacrifices himself to destroy the meteor with an Unluck-summoned comet disintegrating the both of them. Fuuko then jumps down into the gate Move summoned for Sick, finding herself in the Roundtable of the Ten Master Rules.
