I. Human Period: Hakuji—A Martial Arts Genius Awakened in Adversity
Core Battle Power: Exceptionally Talented Physical Combat + Protective Obsession
Akaza's real name was Hakuji, born into a poor family in the Edo period. Due to his naturally sharp fangs, he was considered an outcast. At the age of 11, his family passed away, and to buy medicine for his seriously ill father, he resorted to stealing. Through repeated street fights and punishments, he honed his physical strength far beyond that of ordinary people—at 15, he could still remain conscious after receiving a hundred lashes and could defeat adult men with his bare hands.
After meeting his master Keizo, Hakuji learned formal martial arts at the Soryu dojo. His desire to protect his ailing fiancée, Koyuki, fueled his obsession to "become stronger than anyone else." In this stage, his battle power stemmed from pure physical strength and a protective heart. He lacked flashy techniques, yet he could break real swords with his bare hands and defeat nine disciples of a swordsmanship dojo single-handedly, becoming a martial arts genius whom no one dared to challenge on the streets.

II. Early Stage of Demon Transformation: Akaza – The Nascent Fighting Demon with Amnesia
Power Leap: Demon Body Regeneration + Blood Demon Art Awakening
After his master and Koyuki were poisoned and murdered, Hakuji completely broke down. After single-handedly slaughtering 67 people, he lost his way and was forcibly transformed into a demon by Muzan Kibutsuji, taking the name "Akaza." Having lost his memories, he was left with only the obsession to "become stronger," leading to his first qualitative leap in power:
• Enhanced Demon Body: Possessing unlimited regeneration abilities, ordinary swords cannot inflict fatal damage, and his physical strength far surpasses his human form;
• Blood Demon Art Awakening: His techniques originate from his human-era martial arts and Koyuki's snowflake hairpin, giving rise to the "Destructive Killing" series, such as Compass and Chaotic Style, centered around (fist fighting), accompanied by blue fighting aura effects, resulting in astonishing destructive power;
• Physical Transformation: Pale skin, short pink hair, upper body covered in dark blue tattoos (a combination of sin and demon markings), wearing a purplish-red short shirt, and prayer beads on his ankles, becoming a highly recognizable fighting demon.
In this stage, he fought a deadly battle against the Flame Hashira Kyojuro Rengoku in the Mugen Train arc. Although he had the advantage of regeneration, he was shaken by Rengoku's willpower, laying the groundwork for his subsequent power evolution.

III. Upper Rank Three: Peak Combat Power – The Ultimate Demon Who Overcame the Decapitation Weakness
Peak Combat Power: Technique Deployment + Breaking the Limits of Demons
After two hundred years of battle refinement, Akaza became Upper Rank Three, reaching the pinnacle of demon combat power. In the Infinity Castle arc, he displayed astonishing strength:
• Technique Deployment: Facing the combined efforts of Tanjiro and Giyu Tomioka, he unleashed "Destructive Killing Technique Deployment," transforming the Infinity Castle into a fighting arena, each move accompanied by spatial distortion effects, his punches powerful enough to shatter buildings;
• Breaking the Limits: During the battle, he overcame the fatal weakness of demons – decapitation. Even when his neck was severed by a Nichirin Blade, he could regenerate, becoming an almost immortal being;
• Will and Obsession: Only after recovering his human memories did he self-destruct in the sunlight. This initial intention of "becoming strong to protect" gave his combat power even greater spiritual weight.
At this stage, he was Muzan Kibutsuji's most trusted Upper Rank, and also the most loved and hated combat power ceiling in *Demon Slayer*.
