Through 99 Underground Levels of Osaka Castle

I was chatting with some friends about the Osaka Castle dungeon in Touken Ranbu, and suddenly thought that this event sounds like the opening of a horror story.

Every floor has the same layout, ghosts [Time Retrograde Army] roam around, and the stairs go on forever.

Imagine a girl falling asleep on the subway during the pandemic. She wakes up to find the train empty, the world outside pitch-black, and the doors open. She gets off and realizes she's at the wrong station. The whole subway station is like a maze, with every floor laid out exactly the same.

It's also incredibly dark inside the station, so she can't see what's even one step ahead. After finally escaping to a small room, she finds a box inside: a resource cache and a koban box.

Thinking about it, there's no way the girl would survive. If she can't beat the enemy swords, she won't be able to recruit any sword boys.

After thinking it over again, maybe she could survive. I remember there were only two enemy swords on the first floor. She could grab a fire extinguisher from the subway station, smash it into the enemy short sword's face, then whack it twice to beat it. Recruit one Awataguchi short sword?
