Azami (Voice: Marie Keda)

A mysterious girl who happens to visit the hotel the protagonist lives in. A cheerful and carefree young woman with an ever-present shadow, she ends up being hunted by the yakuza after a client dies on her.

Haruhiko Nire (Voice: Netoru Irakusa)

An elite detective from Tokyo Metropolitan Police Department’s First Detective Division who wanders Kabukicho, seemingly in search of something, even though his beat is actually East Shinjuku. While he may look kind, he’s a shrewd man who knows not just judo and kendo but various other practical martial arts as well.

Sayuki Ugai (Voice: Ren Kureno)

A detective from East Shinjuku’s Detective Department Section 4 who’s lost any shred of morals or sense of duty. With her propensity for violence and greed, it’s no surprise she’s in the pocket of the Aoike Gathering who rule Kabukicho’s underbelly.

Mirei Bessho (Voice: Murasaki Fujino)

A brash and intelligent but stubborn young woman. She met the protagonist in Kabukicho and became fast friends with Azami.

Yun Shi Gu (Voice: Jimu Kyari)

The owner of an illegal business in Kabukicho. When he was young, he was the leader of a group of hot-blooded Shanghainese militants. Now he has been reduced to scraping together a living under the watchful eyes of the yakuza and the police, yet this does nothing to deter him from sticking it out in Kabukicho.

Li Jian Rong (Voice: Yukine Takane)

The elderly driver for Yun’s illegal business. Being a warm and sincere man who’s well-liked by the ladies he chauffeurs belies the fact that he was once the boss of Yun and a legendary Chinese gang who exercised power over Kabukicho.

Lady Dharma (Voice: Mako Ayane)

A wheelchair-bound, limbless mass murderer who has weapons stowed within her prosthetic legs. Her modified wheelchair tops out at 50 KPH, allowing her to hunt her prey to the ends of the earth. She’s become something of an urban legend in Tokyo.

Mamoru Tougi (Voice: Torowa Ando)

The leading subordinate of the Aoike Gathering, the secondary organization under the large-area designated yakuza group known as the S Gathering that rules Kabukicho. A rising star in the organization, he’s one of the candidates to become the leader of the Aoike Gathering. He’s a man of few words and great restraint with the ruthlessness to kill anyone without hesitation should it be required.

Shinsuke Kaieda (Voice: Tetsuto Furukawa)

A member of the Aoike Gathering and assistant to Mamoru Tougi. He’s a bold and unflappable as well as crafty, modern kind of man. Lacking the usual concern for his reputation and pride of yakuza members, he’s willing to work with anyone and everyone to achieve his goals.

Kazuyoshi Mifune (Voice: Tooru Kishiri)

The head of the S Gathering’s third faction, the Mifune Group, and second lieutenant of the Aoike Gathering who’s also in the running to be next in line. He’s an old-school yakuza with an appetite for alcohol and a good time on par with his brute strength. Merciless and cruel but compassionate to his people, he’s a hero to his subordinates.

Meng Feng Da (Voice: Goro Ide)

A suspicious thug who roams Kabukicho, committing fraud, fencing stolen goods, and cleverly navigating the lines between every faction from the yakuza to the Chinese gangs to the police. He’s also corrupt cop Sayuki Ugai’s pet informant.

Onda (Voice: Kazuki Nishizaki)

Just your regular balding, middle-aged day laborer who gambles away his pay on horse or bike track races most days. With his easygoing smile, he’s pretty approachable.

The Crone (Voice: Megumi Nishikiori)

The old woman who owns the hotel the protagonist lives in, working him like a dog. She’s a well-informed member of the Kabukicho underworld who has ties to the Aoike Gathering and knows about both the protagonist’s hit man side hustle and Yun’s gang member past.

“Me” (Voice: Ryo Sugisaki)

A hit man who suffers from insomnia that renders him eternally sleep-deprived. He’s Japanese—and went by Takeo Muraki for a time—but operates under the Hong Konger identity of “Zeng Heixing” and has made a home for himself in one of the rooms in a hotel on the outskirts of Kabukicho. Normally, he spends his days working there apathetically and only kills anyone when a job comes in. After meeting Azami and getting the best sleep of his life, he can’t bring himself to let her go.
