Clearing an Isekai with the Zero-Believers Goddess

The frontlines against the demon lord army, the Black Barrel Fortress.

A solid fortress made at a slightly elevated mountain with dry moats at its surroundings and a number of barricades.

There isn’t much point against flying monsters, but it should show a certain degree of effectiveness against the monsters on land.

A boorish barricade that continues endlessly in this barren wasteland.

There’s what seems to be the bones of monsters lying around here and there.

We stood in front of the giant iron gate that’s slightly separated from the fortress.

The door was tightly shut.

While we were looking around restlessly wondering where to enter…

“You bunch, state your names.”
