Demon Slayer: When the Sun Comes Up, I Climb the Hillside

The Demon Slayer Corps was exhausted from slaying demons all night,

with nothing to do during the day!

On a deserted island, a scientist conducted meticulous research and created a demon that could withstand sunlight, filling the gap in the Demon Slayer Corps’ daytime demon-slaying schedule.

(The scientist has since been arrested and is being interrogated by the three remaining Hashira.)

But the sun-proof demons have already spread far and wide!

With no other choice, the three Hashira trained a new corps of daytime demon slayers.

And so the hapless members of the Demon Slayer Corps began their tireless demon-slaying careers once again.
