Thanks for the translation as always. To be honest, even if mokou died, i think she won’t meet the same judgement as keine. With a millennium worth of sin, i don’t think shikieiki would approve it, especially including killing the guy that she was supposed to serve and rob their dead body of the hourai elixir.
Reversing mokou’s immortality might also kind of invalidate a lot of thing, not in a good way. The ending is a happy ending i might say, but it kind of trivialize all of the pain and suffering. Most of all, i think mokou shouldn’t die a normal human death. Hourai’s elixir immortality is supposed to be “eternal and unchanging” which even if they’re able to make mokou die, it shouldn’t be because of the immortality got reversed, but instead, it should be a workaround, like forcefully splitting her soul and her body. Her death should not be a natural death. The weight of immortality means nothing if we can choose when to end it.
But still, it’s still a nice little story. I can imagine how now mokou cannot escape shikieiki’s yapping now that mokou also cannot escape death.
