The race to obtain the lost Ainu gold is nearing its peak, as even more formidable ex-prisoners are set on keeping their tattooed skins intact. Saichi "The Immortal" Sugimoto and Asirpa can finally move forward together, but Asirpa's time with Kiroranke and Ogata Hyakunosuke has slightly altered her ambition and strengthened her determination. As their party leaves the Russian territory, they gain a peculiar follower. Meanwhile, Toshizou Hijikata's crew makes major moves to get invaluable skins, falling into the poisonous trap of a dangerous convict. Although each group possesses a strong advantage over the others, even First Lieutenant Tokushirou Tsurumi—the most powerful and ruthless contender—cannot advance without Asirpa's help. However, his ominous plans for when they will inevitably meet remain a mystery.

A powerful necromancer known as the Corpse God dies during a legendary battle, only to be reborn as Polka Shinoyama, a young boy in modern-day Tokyo. In the process of trying to adapt to his new physical body, he gets targeted by various groups that deal with the supernatural. Among them is Misaki Sakimiya, a high school girl who can see spirits and is out for his blood from the very moment they meet. Attempting to make sense of this situation where unknown parties want him dead, Polka eventually meets Takumi Kuruya, a contractor skilled in surveillance and hacking, and Lisa Kuraki, a crime boss operating out of Shinjuku. Alongside these—and other unexpected—allies, Polka braves danger to reveal the truth of his reincarnation and the fate awaiting the world he now lives in.

Second half of Kengan Ashura.

Foolhardy police officer Brian Nightraider is dismissed from the force for a history of reckless behavior that ultimately resulted in his partner's death. While wallowing in self-pity, the disgraced officer receives a curious invitation from the United Nations Immigration Bureau Special Investigation Unit. He has been recruited to join the Marginal Service, a secret underground branch of the UN tasked with handling Borderlanders. Indistinguishable from humans, Borderlanders are aliens that peacefully coexist in society. But now, a Borderlander terrorist organization has emerged, manufacturing and distributing a potent drug called Confu. With the Borderlanders' ability to regenerate and blend in as humans, uncovering the drug-trafficking ring will be no easy undertaking. However, the ragtag group at the Marginal Service are not one to back down from a challenge—even as their work exposes some unexpected figures as Borderlanders.
