Mystery Illness Time

Studying for finals is hard. Staging an assassination against an unkillable target is impossible. Even worse? Attempting it all whilst carrying your best friend's baby, of which you barely even remember... well, creating. Nagisa didn't know how his life had ended up like this.

(Also known as the fic where Nagisa gets knocked up through an unlikely turn of events, Karma doesn't know how to deal with it, and the author has no idea what they'd have done if they didn't end up becoming literal billionaires)
