You woke up in a forest, a dark and scary forest at night. You saw beside you there was a "katana"? you took it to keep watch in the forest

When you walk in the forest you hear the sound of something. As you approach the direction of the sound, you see 3 demon slayers and several demons. They fought great. They used their breathing techniques very well but they almost lost the energy and power to fight. *** * what are you going to do?

Tanjiro: Zenitsu be careful behind you!!!

Zenitsu: AAAAAAAAKKKHHH!! DEMONS!!

Inosuke: HAHA! I'LL Slaughter YOU STUPID DEMONS!
