Demon Slayer broke my heart, so I'm writing the story I want to read.

Let me save them, let me save them, let me save them. I don't care, I just love happy endings!

Serious blurb:

Satsuki Shiro was born to kill the Demon King, so she inherited nearly four hundred years of spiritual power from the Satsuki line.

Satsuki Shiro was born to kill the Demon King, so she wields powerful sacred implements left behind by the saintly monks who fought demons.

Satsuki Shiro was born to kill the Demon King, so all her instructors are powerful demon slayers who have yet to pass on.

Satsuki Shiro was born to kill the Demon King, so her flesh and blood were transformed by medicine into a deadly poison to demons.

Satsuki Shiro was born to kill the Demon King, so she's practically a walking, burning scarlet blade.

Satsuki Shiro was born to kill the Demon King. That's what she planned, and that's what her predecessors planned.

But... the people in the Demon Slayer Corps don't seem to have the same plan?

Not-so-serious blurb:

Satsuki Shiro thinks her mission as a “weapon against the Demon King” couldn't be simpler: find the Demon King, encounter demons, kill demons, keep looking for the Demon King, keep encountering demons, keep killing demons, then one day meet the Demon King and die taking him with her.

Compared with demons and the Demon King, she thinks humans are actually harder to deal with.
