Hello,

I'm looking for a manga I recall reading in the last six months,

It stars siblings m/f, possibly twins, on the onset of an apparent zombie apocalypse that is supernatural/spiritual in modern urban japan. The two get split up and the brother is saved by their guardian, who turns out to be a mercenary hired by their father to protect them. They go back into the city to find/rescue the sister, while also leaving for a safety zone that's separated by a large rift in the ground. Along the way they meet up with surviving JSDF that try to link up with survivors/the safety zone as well.

There are spiritual aspects involved, I recall a girl able to pull out a sword from her body, as well as some background of some old family that prevented the disaster from occurring, but was betrayed by the strongest girl in their family, with the sole survivor helping the mc. They also run into a man that was originally from the same clan as the girl as well, that has lived long past a normal lifespan.

Spoilers for sorta gory details

in the end the sister's body or head, can't remember, was separated and attached to the spirit's head/body, but in the end is saved somehow and survives

The series was less than 50 chapters I believe, and had nice detailing/clutter drawn in.

Any help is appreciated! 🙂
