Tokita Ohma, nicknamed “The Asura,” emerged from the lawless enclave of The Inside, where he survived childhood abandonment through ruthless theft and street violence. His life shifted when Tokita Niko, a martial arts master, took him in and rigorously trained him in the Niko Style—a combat system blending versatile techniques, including the lethal counterattack Demonsbane. Ohma honed his skills through grueling trials, such as ceaseless sparring in weighted gear, forging both resilience and mastery.

A turning point arrived when The Other Tokita Niko, a rival practitioner, forcibly etched the Possessing Spirit (Advance) into Ohma’s psyche. This volatile technique supercharged his physical prowess by overtaxing his heart, but at a dire cost: progressive organ failure and eroding memories. Despite the toll, Ohma repeatedly unleashed the Advance in tournaments, hastening his body’s collapse.

Once brash and dismissive, Ohma gradually tempered his demeanor, forging loyalty to allies like Kazuo Yamashita, a corporate manager turned confidant. Their bond deepened as Ohma shielded Kazuo from danger, shifting from lone warrior to trusted protector. Though initially uneasy around Karla, a fellow fighter fixated on him, he navigated her advances with newfound composure after reclaiming fractured memories.

Ohma’s tournament path saw him triumph over formidable rivals—Lihito, Sekibayashi Jun, Wakatsuki Takeshi—before facing Kuroki Gensai in a final, devastating duel. Repeated Advance use left him mortally wounded, yet he defiantly fought on, embracing death as a warrior’s worthy end. His passing cemented a legacy of honor and self-determination, inspiring peers like Kazuo and successors.

Physically imposing with a muscular frame, tan skin, and wild dark hair, Ohma transitioned from ragged streetwear to tournament gear like light-blue trunks. Though he overcame illiteracy and social hesitance, he retained a blunt, informal speech style, addressing most by full names—except Kazuo, whom he referenced with unspoken warmth.

Struggling initially with Tokita Niko’s legacy, Ohma ultimately embraced the Niko Style as his own, reconciling his turbulent past with his mentor’s teachings. This acceptance mirrored his broader growth from rootless survivor to disciplined inheritor of ideals.

In later years, Ohma mentored Narushima Koga, imparting hard-won wisdom, and secured victories in cross-organizational bouts against fighters like Rolón Donaire. Chronic Advance use, however, ravaged his body—memory gaps, cardiovascular decay—underscoring his choice of legacy over longevity.

Posthumously, fighters paid homage at his grave, while sequel narratives echoed his impact. Kazuo adopted leadership roles shaped by Ohma’s ethos, and even Kuroki acknowledged his indomitable spirit as a testament to martial honor.
