[Demon Slayer + Touken Ranbu + female protagonist + no romance + salvation-focused]
After Ling joined the ranks of Warden Examiners in the apocalypse, she plunged straight into a series of pioneering missions. The historical timelines were full of bizarre anomalies: during the Taisho era, creatures called demons had appeared. Ling's mission was to eliminate every demon and stabilize this abandoned parallel timeline.
The sword-wielding tsukumogami, serving as "historical vaccines," secretly joined the Demon Slayer Corps to save those who "were never supposed to die." Even Ling, the Master, wielded a strange machete from the apocalypse and racked up an impressive record of her own.
Before leaving the world, Ling looked at the entire Demon Slayer Corps, whose members nearly filled the frame of a modern camera, and smiled. Under everyone's astonished gaze, she activated the time-space transporter. The tsukumogami transformed into swords and vanished from that era, bidding everyone farewell.
"Live well," she said. "May you be spared this suffering for the rest of your lives."
And with that, the mission was complete.
