Synopsis:
On the night gunfire rang through the concentration camp, Kaori Kokonoe, a Creation ability user, took two bullets from Tsurugaoka and died protecting a reincarnation ability user. Unexpectedly, a rift in space and time dragged her into the Taisho era, dropping her right into the Ubuyashiki Estate, where she came face-to-face with the Hashira.
Mistaking her situation for a deadly threat, she turned her own flesh and blood into blades and fought her way out, only to run into a Lower Rank demon. Her anatomical expertise let her strike with precision, but ignorant of demons' regenerative powers, she was gravely wounded and on the brink of death. Fortunately, the Tokito twins found her and took her in, giving her a taste of warmth she hadn't felt in a long time.
Amane Ubuyashiki visits and reveals the truth. To protect the twins, Kaori joins the Demon Slayer Corps and becomes a member of the Butterfly Mansion. She uses modern medicine to make up for gaps in medical care and save lives with pharmaceuticals. She creates flesh-and-blood weapons to restrain demons from afar and incorporates her anatomical knowledge into Insect Breathing, forging her own path to slaying demons. As the shadow of Tsurugaoka intertwines with Muzan's schemes, she will protect the people she treasures with all the care of a healer, cut down every demon with her blade, and find her own path to survival through redemption.
Also known as: Demon Slayer + Talentless Nana: The Longest Night
P.S. If I'm not mistaken, the male lead will probably be Yuichiro Tokito. But since the kids are underage, the actual romance will likely happen in the modern-day arc or in an extra...
I have some original headcanons about why the Talentless Nana manga hasn't finished.
The demon slayer part is well written, and the writing and characters are great! There are a lot of incompetent Nana. I haven't watched this show and can't understand it just by relying on the heroine's memories, obsessions, and soliloquies! Although there are a lot of related words in the other series, it is fragmented, and it was really painful for me to watch it as I have never watched Incompetent Nana. The demon slayer part is also very well written, and I can't bear to abandon it directly 🤦
I won't comment, but it looks good! ૮₍♡>𖥦<₎ა Come on, author!
