Third season of Mo Dao Zu Shi.

"City Hunter" is a notorious contractor group with the call sign "XYZ." No matter the job, they will take it, cleaning up the scum on the streets of Tokyo. The key member of City Hunter is Ryou Saeba; armed with his trusty Colt Python and pinpoint accuracy, he works alongside willful tomboy Kaori Makimura. Together they solve tough cases and tackle the numerous dangers that accompany their trade head-on. However, when he's not out hunting crooks and villains, Ryou finds pleasure in chasing beautiful ladies with only Kaori and her one hundred-ton hammer to keep him in check. From pickpockets and arms dealers to crime syndicates, nothing can stand in the way of Ryou Saeba when he takes aim at his next mission. [Written by MAL Rewrite]

Akutabe is a detective who summons devils to solve the troubles of his clients. One day, a low class devil Azazel Atsushi is summoned by Akutabe and is used harshly by him and his assistant Rinko.

Tricked into assassinating his own prospective father-in-law, righteous samurai Raizou Kurima is overwhelmed with guilt. In order to reclaim his honor, Raizou swears vengeance on the lord who gave him those misleading orders. In his pursuit, he is aided by self-proclaimed merchant-of-all-trades Yuuen Usui, who is actually one of the Revengers—assassins who seek justice for the wronged and dispense bloody revenge on their behalf. Tragedy seems destined to follow Raizou as he becomes increasingly intertwined with members of the Revengers. As he begins working as a vigilante alongside them, the complicated web between the corrupt Japanese political elite, the unscrupulous Europeans, and the Revengers gradually reveals itself. The more entangled he becomes in these affairs, the more Raizou realizes that justice is as deceptive as the honor that he sought to redeem.
