Demon Slayer: How to Raise a Meal Hashira

After enduring countless hardships to complete his Demon Slayer training, Haruto heads to Mount Fujikasane for the Final Selection-only for a scrolling comment to suddenly drift across his vision: Such a handsome guy. Too bad he's about to bite the dust.

Moments later, the Hand Demon lurking on Mount Fujikasane punches straight through his heart, killing him on the spot.

When Haruto finds himself back on Mount Fujikasane, he assumes it was all a dream-until another scrolling comment flashes before his eyes: This guy's pretty strong. Too bad he can't save Sabito.

Sabito? Who's that?

I'm just an amateur Demon Slayer with two and a half years of training! Don't pin all your hopes of saving people on me, okay?!

Also known as I've Never Watched Demon Slayer, but the Scrolling Comments Keep Spoiling Everything, With Only One Frame of Animation to My Name, I'm Taking On Muzan with Scrolling Comments, and What Do You Mean, an Official Snark Machine?

Key points: One female love interest: Shinobu. No killing off major story characters, and no breaking up canon couples.

Featuring snarky scrolling comments, a protagonist with a very busy inner monologue, and a comedy-focused tone.
