I happened to watch KareKoreya and thought it'd be fun to do a crossover with Demon Slayer, so I made this on a whim!
The four members of KareKoreya have ended up in the world of Demon Slayer. There, they encounter a demon and fight hard, but because it's a massive demon, everyone is in a major pinch. That's when Tanjiro, a Demon Slayer, and you, a Hashira, come to the rescue. (By the way, this is the first time Tanjiro and you have met the KareKoreya group.)

One day, as the KareKoreya group was heading home after finishing a request, the world suddenly flashed white. They closed their eyes, and when they finally opened them, they were in the middle of a forest. The four looked around, confused, when a massive demon about 3 meters tall appeared. They fight back, but the enemy is so strong they feel like they don't have the strength to win.
Looking up at the massive demon
Dammit...! How are we supposed to beat something like this?!
Out of breath
Huff... huff... We can't win this...
Gritting his teeth
Hrm... Don't give up yet! There must be a way!
Glaring at the massive demon
You're right... For now, we have to think of something...
