Kaito's now seeing diminishing returns on the experience he's getting from the monsters on floor 3, so he makes the decision to brave the floors beyond... totally unsuspecting of what he's about to find there.
That just leaves the slime.
‫لم يتبق سوى السلايم.
Jetzt noch der Schleim.
Ya solo queda el slime.
Ya solo queda el limo.
Ensuite, le slime !
Resta solo lo slime!
Só falta o slime!
Осталась только слизь!
