THORN queen: WILD ADAPTER

"W·A," later identified as "Wild Adapter," is the name of a dangerous drug which transforms its users into an animalistic state; the users exhibit superhuman strength and a berserker mentality until the drug causes his or her organs to explode, effectively killing them. The corpses left behind by W·A are covered in fur and sport cat-like claws. The police are baffled by W•A even as they investigate the remains of W·A users, and the Yakuza wants it. Two powerful rival yakuza groups, the Izumokai and the Toujougumi are fighting to figure out and gain control of the source of W·A, a task made harder by the fact that no user of W·A have managed to stay alive after consuming the drug.

Amid this, 17-year-old Kubota, the first of two main protagonists, have somehow managed to stumble into the position of Head of the Izumokai youth group, despite not being a gang member before that. He is aided by the second-in-command, Komiya, in his yakuza jobs and it is through Komiya that he knows of the existence of W·A. Komiya is killed by the rival Toujougumi gang when investigating W·A, and Kubota quits the gang after Komiya's death, but not before taking out twelve high-ranking members of the Toujougumi gang, and disappears from the yakuza world.

Soon after, Kubota picks up a stranger with amnesia whom he names Tokitoh, and they start living together. Tokitoh has no idea of his identity, or why his right hand is a furry, clawed paw identical to the animalistic bodies of dead W·A users, yet he is still alive. Kubota and Tokitoh then set out on a mission to investigate W·A, hoping to discover Tokitoh's past at the same time. The manga details their quest to investigate every victim of W·A, and following up on any leads provided by Kou, a drugstore owner who is Kubota's current employer, or Kasai, Kubota's detective uncle. These tips however are usually red herrings or traps and lead nowhere.

In the process, Kubota and Tokitoh often get mixed up with the yakuza who are just as eager to seek W·A. Sanada, leader back of Izumokai gang and Kubota's former employer is fascinated by Kubota, and constantly keeps tabs on him. Sekiya, leader of Toujougumi just wants to get his hands on W·A. In their various clashes with the yakuza Kubota and Tokitoh rarely emerge unscathed, but they always manage to survive and make it out somehow, ready to follow the next lead.

Tokito Minoru

Tokitoh is first introduced as a boy running from pursuers. He collapses, unconscious, in an alley, where Kubota finds him soon after leaving the Izumokai. Tokitoh's right hand is that of a beast's—and that of deceased W·A users—and it occasionally causes him immense pain. He keeps it covered by a black glove. He has no memory of his past before Kubota picked him up, other than flashes of a menacing figure who calls him "Minoru." Tokitoh is loud, impulsive, stubborn, and tactless at times, but he is straightforward, kind-hearted, and a very loyal ally.

Kubota, along with several other characters, refers to Tokitoh as a "cat," or "stray cat." Tokitoh calls Kubota "Kubo-chan." Tokitoh is highly protective of Kubota, and gets jealous easily when he thinks someone else is closer to Kubota.

Kubota Makoto

In volume one of Wild Adapter, Kubota is 16. He becomes leader of the Yakuza's Izumokai youth division when he is offered two guns; one of them is dangerously defective and the other is safe and functional. He chooses the functional gun and executes the youth division's previous leader who was revealed to be a spy from the rival Yakuza. Kubota leaves the Izumokai after only seven months, and a year later, re-emerges as Tokitoh's guardian.

He is seen as calm, collected, and focused, as well as cool, callous, and aloof. He is cruel and insensitive, but at the same time, childish and sweet. To both friends and enemies, they find him terrifying at times—whether because he can insensitively break a man's arm, or because of his smile. He is never seen without a cigarette, and his favored brand is Seven Stars.

Komiya, in volume 1, says he has no logic to him. He says, "Interested in nothing, yet fiercely curious about everything. Acts like he doesn't care, but with so much desire in his eyes. Only caring for himself, but completely masochistic. Needing nothing, clinging to everything. Chaos existing inside tight order...All of these fevered colors merging into black...and disappearing. He's just like this city."

Kubota is extremely possessive of Tokito, and is a very talented mahjong player.
