A killer travels to the world of death and lives an ordinary life...
The time travel is part of the extra story, which is about the blank period when the Masked Legion was just expelled from Soul Society...
So there will be a bunch of original characters to fill in the gaps.....
Don't have extravagant expectations. The heroine is very strong, but basically she won't do anything extraordinary. She should live a very ordinary and ordinary life...
Probably...
