Sword of the Demon Hunter episode 6 highlights

Sword of the Demon Hunter episode 6 picked up from the events of episode 5, with Naotsugu escorting Jinya to his house in order to further investigate Sadanaga Miura's disappearance.
Jinya enters the samurai's residence and gets greeted by Naotsugu's mother in a much more formal and polite way than he expected, given his status as a nameless ronin.
Eventually, Jinya investigates the belongings left behind by Sadanaga and realizes that he must've been whisked away by a demon.
He requests to investigate Sadanaga's personal room, which ends with both him and Naotsugu being whisked away into a separate dimension.
Soon, the dimension shows them visions of a young girl losing her parents and home to a fire.
Overcome by the grief and despair, she inadvertently turns into a demon, only to get ostracized by humans despite not having any ill intent towards them.

Eventually, the girl reveals herself in front of Jinya and Naotsugu, mentioning how the garden they stand in is a result of demon abilities.
Apparently, the garden was a separate dimension created from her memories, which constantly replay the memories of her parents from her childhood.
Naotsugu tries to enquire about his brother Sadanaga, only for the demon girl to reveal that Sadanaga was indeed here with her.
The girl goes on to unveil how Sadanaga once stumbled into this garden and refused to leave her alone, and spent a really long time in this dimension keeping her company.
Apparently, Sadanaga realized that the demon girl had been lonely for centuries and decided to become her father. Soon, she dispels the garden, urging Naotsugu to move on and realize that Sadanaga Miura was a really kind person.

Naotsugu and Jinya meet back at the Soba restaurant, where Naotsugu thanks Jinya for his help and accepts that he should just move on.
Both Ofuu and her father thank Jinya for helping Naotsugu under their request. Soon, Jinya starts assessing the transpired events, coming to the conclusion that Ofuu's father had mentioned Naotsugu as "Arimori" previously.
Given that real names of samurai like "Arimori" are only known to lords or family members, Jinya deduces that Ofuu's father was Sadanaga himself.
He goes further and realizes how Sadanaga must've aged due to the accelerated time within the demon girl's garden within one month of real-life time.
As a result, he abandoned his identity as Sadanaga Miura and started the run-down soba restaurant.

Ofuu's father, faced by the accurate theory, relents and reveals that he indeed is Sadanaga Miura while simultaneously revealing that he knew Jinya's identity as a demon.
Jinya further enquires about what the demon girl was doing now. Sadanaga simply mentions how she's been right beside him all these moments as Ofuu.
Ofuu asks Jinya what he'll do next, since demon hunting is his job and she herself is a demon.
Sword of the Demon Hunter episode 6 ends with Jinya simply ordering a bowl of Soba, content with the fact that Naotsugu, Ofuu, and her father have moved on from their past.
Final thoughts
Sword of the Demon Hunter episode 7 will be released on May 13, 2025, and follow a different mystery around a painting cursed by a demon.
While the episodes so far have gradually pushed Jinya towards accepting his own emotions, while simultaneously gaining closure to his biological father.
Episode 7 will apparently bring closure to Jinya and his father's estranged relationship.
