Sword of the Demon Hunter episode 12, titled Drunken Dreams of the Lingering Snow Part 2, premiered on June 17, 2025, and began the next major arc centered around Jinya and Suzune's reunion ever since the events of episode 1.
Although Suzune essentially declared war on humanity in the first episode itself, episode 12 revealed that she had planned a meticulous operation, centered around simply turning humans into demons by feeding into their negative feelings and indulgences.

Sword of the Demon Hunter episode 12 highlight

Sword of the Demon Hunter episode 12 picked up from the ending of episode 11 with Somegorou Akitsu and Jinya returning to Ofuu's soba restaurant. Although the civil unrest hadn't reached critical mass, wrongdoers were already showing up at Ofuu's restaurant. Fortunately, Jinya, alongside Somegorou, were able to repel them.
Eventually, Jinya went on to reveal his ominous hunch about Yuki-no-Nagori, instructing Natsu to stop their father, Juuzou, from consuming any more of the wretched alcohol. Although the alcohol had resulted in civil unrest so far, its truth soon came to light right in front of Jinya and Somegorou. Apparently, the alcohol had the ability to transform anyone who consumed it into a demon.
After defeating one such transformed demon, Jinya and Somegorou left to track down the actual origins of the alcohol, which ended up being a prominent bar within Edo. Apparently, the bar owner was approached by a blonde-haired, pale-skinned woman, promising him unimaginable wealth if he were to sell Yuki-no-Nagori.
Realizing that the ominous drink was being supplied by Suzune, Jinya tried to seize and destroy the entire stock. Unfortunately, the bar owner opposed the idea and started consuming the alcohol in heavy amounts, resulting in his rather grotesque transformation into a demon.

Both Somegorou and Jinya engaged the demon in combat, only for Jinya's sword to prove ineffective in front of it. Given Juuzou's regular consumption of Yuki-no-Nagori and the overall threat that the rampant demon transformation possessed, Somegorou offered to engage the demon alone while Jinya rushed to Natsu and Juuzou's side.
Apparently, Juuzou was once again consuming Yuki-no-Nagori against all advice, even offering Natsu some of the drink. The episode soon ended with Jinya bolting to Natsu and Juuzou's location as an eerie monologue from Suzune played.
Final thoughts
Sword of the Demon Hunter episode 12 served as a transition into the next major arc of the series, hinting at an all-out war between humans and demons within the borders of Edo.
Given the convergence of strong demon hunters like Somegorou Akitsu in Edo, the future episodes may take a much more action-oriented turn, contrary to the detective mystery format followed by the series.
