how strong was tanjiro's father

Tanjiro's father, Tanjuro Kamado, was exceptionally strong despite his frail body and illness. He mastered the Hinokami Kagura dance, which is the Sun Breathing technique, and was able to perform it all night long without rest, indicating immense stamina and latent strength. Though he was not officially a Demon Slayer and never wielded a Nichirin sword in battle, his skills and endurance were extraordinary enough that he could have rivaled high-level fighters and potentially faced powerful demons like Muzan Kibutsuji. Tanjuro was able to foresee opponents' attacks by seeing their blood flow and movement, a rare ability among Demon Slayers. His strength and calm demeanor were likened to legendary figures such as Yoriichi Tsugikuni, the strongest Demon Slayer in history, suggesting that Tanjuro was close to that level in skill and power. In summary, Tanjuro Kamado was likely a Hashira-level warrior in natural ability and skill, capable of incredible feats of strength and endurance and possessing profound combat insight, despite never formally joining the Demon Slayer Corps or using a sword in battle.
