Raising Kids in My Stepfather's Home [Demon Slayer]

Blurb:

Jiguo Yeyin is a second-year student at the junior high division of Kimetsu Academy.

After touching a strange shrine at home, she seems to have gained the ability to transmigrate involuntarily.

Then she discovers that this involuntary transmigration can bring a companion along, too!

Now the problem has changed. She transmigrates with Kanae Kocho, a teacher at Kimetsu Academy's senior high division, and they run into demons. How is she supposed to explain this damn transmigration to her teacher?

While on a mission, the Water Hashira, Giyu Tomioka, saves someone. The moment he sees his former colleague Kanae Kocho, even he, normally expressionless, doesn't know what face to make. Can the dead come back to life?

P.S.:

Updates every other day. The story has three time periods: modern day, the Taisho era, and the Warring States period. Four transmigrations are currently planned, two in each historical era. The blurb describes the first transmigration to the Taisho era.

The Jiguo couple and Iwakatsu take center stage in both Warring States arcs.

OOC warning.
