Tanjiro to Unlock Sun Breathing in Future Demon Slayer Movies

The piece says Tanjiro will gain a major power-up in the remaining Demon Slayer: Infinity Castle movies. It notes that the first film became the highest-grossing anime movie and that Tanjiro fought Akaza alongside Giyu Tomioka. Tanjiro is expected to unlock Sun Breathing in the next installments.
The Infinity Castle trilogy follows a pivotal arc, and the first film’s record-breaking box office success surprised those who doubted a movie adaptation. In it, Tanjiro and Giyu Tomioka confront Akaza, Upper Moon Rank 3, in a grueling battle that highlights Tanjiro’s need for greater strength before facing Muzan.
Sun Breathing is tied to the Kamado family and was created by Yoriichi Sugikuni, described as history’s strongest Demon Slayer. As the first breathing style, it is thought to be the strongest and inspired all others. Tanjiro previously used an imperfect version through Hinokami Kagura, so the remaining films are expected to show him unlocking its full potential.
The continued Demon Slayer films may affect global anime fans, theater chains, and streaming platforms by sustaining interest in theatrical anime. Record-breaking success could encourage studios to adapt major arcs as event films, while fans may engage more with manga, merchandise, and online discussion. For casual viewers, the trilogy may shape expectations for animation quality and franchise finales.
