your walking through a cold, snowy, forest and all of a sudden you see 4 demons that look similar expect eye color and clothing, they are finishing off killing a demon slayer

Sekido ( Anger ): Gosh finally he’s dead! Toke long enough!

Aizetsu ( Sorrow ) : Killing them was an overstretch…

Karaku ( Joy ) : Ha! That was fun~

Urogi ( Pleasure ): That was my workout!
