Hiroshi Furukawa

Biodata

Background / History

Family and motivation

Hiroshi witnessed a demon kill his father and devour his mother. Memories of their screams continued to torment him, and he regarded that night as the point after which he could no longer return to an ordinary life. He joined the Demon Slayer Corps to prevent demons from destroying other families’ happiness 39 53.

Although his mission earnings could have allowed him to retire and start a family, he refused to abandon demon hunting. His ambition was to slay one of the Twelve Kizuki, following the example of Kyojuro Rengoku 6 39.

Departure and the Taro Town hunt

By his first appearance, Hiroshi had killed three demons. Kyojuro praised his efforts and encouraged his ambition, although he privately recognized that Hiroshi was still far from strong enough to defeat a member of the Twelve Kizuki. Before leaving on another investigation, Hiroshi promised to treat him to salt-grilled sea bream and sweet potato rice upon returning 6.

During the mission, Hiroshi learned that his squadmate Murayama had disappeared while searching Taro Town. He led the squad there, where he briefly encountered the neglected Kanao Tsuyuri, gave her loose change, and warned her to go indoors after sunset 15 16.

The squad subsequently fought a demon in a battle that cost several swordsmen their lives. After a companion pinned the fleeing demon with a thrown Nichirin Blade, Hiroshi decapitated it using Rising Scorching Sun. He then discovered unusually deep footprints indicating that another demon had been nearby 22 23.

Investigation and Su Mu’s escape

Rather than pursue immediately, Hiroshi ordered his exhausted companions to rest and instructed the Hidden Ones to trace the footprints after sunrise. The trail ended at a busy town, prompting him to order searches of basements, sewers, and other sunless hiding places, alongside surveillance of missing-person reports 24 27.

When the squad investigated demons killed by Su Mu, they initially suspected the Flower Hashira’s involvement. Hiroshi nevertheless requested confirmation from his superiors and refused to declare the mission complete. A missing squadmate’s Nichirin Blade briefly made him consider whether a demon could be using the weapon, though he initially dismissed the possibility 33 34.

At the town gate, Hiroshi saw Su Mu caring tenderly for Kanao and assumed that such affection ruled out his being a demon. He noticed Kanao’s resemblance to the neglected girl from Taro Town but attributed their different circumstances to different fates. Shortly afterward, a Hidden One exposed Su Mu and was killed; Hiroshi recognized the fleeing pair and blamed his own oversight for the death 38 39 40.

After another comrade’s death, Hiroshi silently cut his hand and let his blood fall beside the corpse. His companions followed his example, renewing their determination to pursue Su Mu 42.

Makomo joins the pursuit

Near Mount Sagiri, Hiroshi sought Sakonji Urokodaki’s help tracking the unusual demon. Urokodaki was about to assist when an urgent message forced him to decline 44 45.

Makomo subsequently asked to join the hunt. Hiroshi initially refused because she had not passed the Mount Fujikasane examination, but offered her a trial when she insisted on following them. After she defeated one of his companions, he accepted her on the condition that she obey the squad’s instructions 48 49.

Over the following months, the group killed other demons without finding Su Mu. Hiroshi noticed that their target left no evidence of feeding: reports showed no missing people, unusual deaths, or missing corpses along his route. Despite recognizing this anomaly, he remained adamant that no demon could permanently resist eating humans 55 63.

During this journey, Hiroshi also helped Makomo interpret Sabito’s presumed death. He suggested that Sabito’s strength had led him to shoulder the most dangerous responsibilities for others 54.

The Kamado investigation

The squad followed its final lead to Saburo’s home, where Hiroshi asked about Tanjuro Kamado and learned of his unexplained illness and extraordinary strength. After Tanjuro died, Hiroshi accompanied Saburo and Tanjiro to the Kamado home, but questioning the family and searching the property yielded no evidence of demon activity 63 69 70.

Hiroshi apologized to Kie Kamado and left money for the bereaved family. With four demons slain during the lengthy mission but their principal target still missing, he ended the search and renewed his invitation for everyone to dine with Kyojuro. Makomo departed for Mount Sagiri, leaving Hiroshi unable to voice his feelings for her 70.

Final battle and death

Immediately after Makomo’s departure, Hiroshi spotted Kanao picking flowers on the mountainside and recognized her as Su Mu’s companion. The squad followed her, believing that Su Mu was keeping her as food. When she warned him and refused to reveal his location, Hiroshi stopped a swordsman from striking her, then correctly anticipated that she would give a false direction. The group followed her footprints to a cave 70 71.

Hiroshi left one swordsman outside with the unconscious Kanao and led the others inside. Su Mu ambushed the group, fatally wounded Ryota, and retreated into a passage too narrow for the swordsmen to surround him 72.

Taking the lead himself, Hiroshi refused to engage with Su Mu’s claim that he was different from other demons. Su Mu’s taunts about a dead teammate provoked him into attacking with Blazing Universe. Their blades struck each other’s necks simultaneously: Hiroshi was completely decapitated, while Su Mu survived a partial severing and killed the remaining swordsmen inside the cave 73.

Urokodaki later told Makomo that the entire squad had died on the day she left them. She blamed herself for departing and vowed to kill the escaped demon, whose trail had been erased by heavy rain 97.

Personality

Hiroshi combined compassion toward humans with an absolute hatred of demons. He gave money to the neglected Kanao and the grieving Kamado family, yet believed that becoming a demon meant losing one’s humanity entirely. This conviction prevented him from accepting Su Mu’s unusual restraint or his affection for Kanao as evidence that he might be different 16 53 55 70 71.

As a leader, he was normally cautious and practical. He prioritized rest over an immediate pursuit, sought confirmation before ending an investigation, and accepted the potential embarrassment of requesting a superior’s help. He also refused to drink while on duty, knowing that impaired judgment or slower sword movements could prove fatal 24 34 39 44.

His composure weakened when comrades died. He had accepted the possibility of his own death, but others’ deaths brought intense grief and anger. Su Mu exploited this vulnerability during their final duel 22 42 73.

In romance, Hiroshi was markedly less decisive. He blushed around Makomo, became flustered by small gestures of kindness, and hesitated to pursue her because he questioned whether someone living a demon slayer’s life should seek such happiness 50 69 70.

Abilities & Skills

Flame Breathing

Hiroshi practiced Flame Breathing and demonstrated three named forms 15 22 23 73.

• Stamina limitation: Neither Hiroshi nor his squadmates had mastered Total Concentration: Constant. Their breathing states could not be maintained indefinitely, and exhaustion left them vulnerable 24.
• Lethality requirement: His final strike cut through more than half of Su Mu’s neck but did not completely sever it, allowing the demon to survive 73.

Squad Combat and Leadership

Hiroshi coordinated attacks to restrict a demon’s movements and exploit openings rather than relying on single combat 22 23.

• Ordered recovery periods and conserved the squad’s strength for possible nighttime fighting 24 27.
• Directed Hidden Ones in reconnaissance and search operations 24 27.
• Recognized that narrow passages negated the squad’s numerical advantage 72.
• Climbed Mount Sagiri’s steep terrain without significant difficulty 45.

Tracking and Investigation

Hiroshi identified a second demon’s presence through deep footprints left during high-speed movement 24.

• Used missing-person reports and searches of sunless locations to narrow a demon’s whereabouts 27.
• Distinguished other slain demons from Su Mu by build and behavior, despite having initially seen his target only from behind 55 63.
• Anticipated Kanao’s attempt to misdirect the squad and confirmed her route through her footprints 71.

Equipment / Weapons / Items

• Nichirin Blade — His primary weapon, used with Flame Breathing to behead demons 22 23.
• Demon Slayer Corps uniform — Close-fitting black clothing identifying him as a Corps swordsman 15 16 45.
• Kasugai Crow — Used to send a written inquiry to his superiors during the town investigation 34.

Relationships

• Kyojuro Rengoku — Admired senior and role model. Hiroshi regarded him as a caring older brother and hoped to emulate his success against the Twelve Kizuki 6 23 24.
• Makomo — Temporary hunting companion and unrequited romantic interest. She respected and admired him but did not share his romantic feelings; his death left her grieving and blaming herself for leaving 49 70 71 97.
• Su Mu — Principal quarry and eventual killer. Hiroshi considered him a cruel, deceptive demon and pursued him despite mounting evidence of behavior unlike ordinary demons 40 49 55 73.
• Kanao Tsuyuri — A child he first helped in Taro Town and later followed to Su Mu’s refuge. He interpreted her loyalty to Su Mu as the result of deception 16 71.
• Sakonji Urokodaki — Respected senior whose tracking assistance he requested near Mount Sagiri 44 45.
• His squad — Companions who addressed him as “Boss.” He protected their recovery time, shared their grief, and promised to introduce them to Kyojuro 23 24 42.
