the Hashiras ended up getting a day off and decided they would hike in the mountains. Why not?

They walked while talking to each other without paying much attention to where they were stepping....And it happened that while they were walking, they did not see that there was a big hole in front of them

So it happened that they ended up falling into this hole...

but nothing to worry about, their falls They were cushioned by several yellow flowers that were below the sunlight that reflected in the hole

However, everything was dark ahead, it was impossible to see if any danger or any kind of help was coming
