In an alternate 2023, the Your Forma, a miraculous smart thread technology initially developed to treat a massive outbreak of viral encephalitis, has become an integral part of daily life. But these convenient devices come with an invasive drawback—they record every sight, sound, and even emotion their users experience. For electronic investigator Echika Hieda, diving into peoples' memories via the Your Forma and hunting for evidence to solve the toughest crimes is all part of a day's work. The problem is, she's so good at what she does that her assistants literally fry their brains trying to keep up with her. After putting one too many aides in the hospital, the top brass finally furnish Echika with a partner on her level, a brilliant yet cheeky android named Harold Lucraft. Does this unlikely duo have what it takes to resolve their mutual suspicions and avert a deadly technological infection from sweeping across the globe before it's too late? (Source: Yen Press)

Following a ruthless attack from an imperialist criminal gang known as the Masked Demons, Shinsengumi's Eighth Division—the law-enforcing squad in Kyoto that remains faithful to the shogunate—is nearly annihilated, with its sole survivor, Heisuke Toudou, critically injured. Urged to rebuild the Shinsengumi by the local feudal lord, Katamori Matsudaira, Toudou decides to offer eight convicts the chance to redeem themselves: they must abandon their old names and become substitutes for the eight Shinsengumi captains. All accept but one, who ends up immediately executed by the former assassin Sakuya. However, Toudou has a hard time transforming the seven reformed criminals into loyal servants. Due to his lack of discipline, the impulsive and vengeful Ichibanboshi, whose family perished at the hands of the Masked Demons, threatens the success of Toudou's strategy. As Toudou pledges to protect the shogunate against imperialists and foreign invaders, other factions, such as Kogorou Katsura's group, start to put their plans in motion with only one goal in mind—to seize power at the dusk of the Edo period.

The 7th Division's Private Hyakunosuke Ogata and former Shinsengumi Vice Commander Toshizou Hijikata find themselves on opposite sides of a gang war in Barato after hearing rumors of the Hidoro gang possessing an escaped prisoner's tattooed skin. With a lead to the hidden Ainu gold close at hand, the two gladly take up arms but a betrayal will force both sides to think twice before carelessly jumping the gun.

In early 1900s Hokkaido after the Russo-Japanese war, Saichi Sugimoto tirelessly pans for gold. Nicknamed Sugimoto the Immortal for his death-defying acts in battle, the ex-soldier seeks fortune in order to fulfill a promise made to his best friend before he was killed in action: to support his family, especially his widow who needs treatment overseas for her deteriorating eyesight. One day, a drunken companion tells Sugimoto the tale of a man who murdered a group of Ainu and stole a fortune in gold. Before his arrest by the police, he hid the gold somewhere in Hokkaido. The only clue to its location is the coded map he tattooed on the bodies of his cellmates in exchange for a share of the treasure, should they manage to escape and find it. Sugimoto does not think much of the tale until he discovers the drunken man's corpse bearing the same tattoos described in the story. But before he can collect his thoughts, a grizzly bear—the cause of the man's demise—approaches Sugimoto, intent on finishing her meal. He is saved by a young Ainu girl named Asirpa, whose father happened to be one of the murdered Ainu. With Asirpa's hunting skills and Sugimoto's survival instincts, the pair agree to join forces and find the hidden treasure—one to get back what was rightfully her people's, and the other to fulfill his friend's dying wish.
