Chiharu Shiba commands respect as the fearless leader of the Tokkoutai racing gang, renowned for his exceptional pain tolerance in brutal street fights. His reputation was forged by surviving motorcycle collisions and single-handedly defeating 100 opponents, securing his place in the Maximum Tournament. Standing 185 cm tall with a slim, muscular physique, Chiharu is instantly recognizable by his vibrant orange-yellow pompadour and brown eyes. A striking three-headed dragon tattoo, reminiscent of King Ghidorah, dominates his back. He typically wears purple pants, tabi shoes, and a white or red jacket denoting his leadership. In the Maximum Tournament's first round, Chiharu confronted judo expert Kouhei Hatanaka. To intimidate his opponent, he deliberately shattered his own left arm before relentlessly headbutting his way to victory. His next match pitted him against boxing champion Iron Michael. Chiharu employed unorthodox tactics, wielding his arm cast as a weapon and binding their legs together with cloth. Though battered by Michael's punches, Chiharu triumphed by breaking the boxer's hands with his forehead, though his own severe injuries forced his withdrawal. He later confronted his substitute, Alexander Gallen, but was swiftly defeated. Chiharu's fighting style hinges on brute force, pain suppression, and triggering endorphin surges. By twisting his ear, he floods his system with endorphins, temporarily boosting his strength, speed, durability, and pain tolerance. This ability first emerged during a pre-tournament brawl following a motorcycle collision, where he felt "power rising". His immense durability and willpower are defining, though his lack of formal training leads to reliance on unconventional tactics and frequent self-harm. Initially, Chiharu exhibits extreme recklessness with minimal regard for his safety. Later, he demonstrates significant maturity: intervening in knife fights to demand fair combat and mentoring Baki Hanma, imparting tactical lessons. He holds deep reverence for Kaoru Hanayama, bowing to him after a tournament loss and dedicating his fight against Iron Michael to him. Their mutual respect is evident when Chiharu's words resonate during Hanayama's battle with Spec. Chiharu later refines his combat skills, evolving beyond street brawling. He successfully replicates Baki Hanma's cockroach dash technique, using it to break an opponent's hand and deform a metal fence. His growth continues in the spin-off "Baki Gaiden: Hana no Chiharu," where he studies martial arts and momentarily unnerves Iaido master Shobun Ron. His weaknesses include a tendency for reckless self-inflicted injury during combat and dependence on endorphin surges, risking long-term physical damage.
