Bosses are strong monsters the player must fight in order to progress to the next floor. At the end of each floor, the player must fight a boss. The boss will be randomly chosen based on which area the player is currently in. Some bosses can be Champions like normal enemies, which can change their pattern somewhat; this occurs more often once the player has beaten the full game for the sixth time and onward. The posthumous-type bosses are lot stronger than their original counterparts and can only appear in alternative chapters.

Mini-bosses take a role as "minor bosses" and appear randomly every time when entering any rooms. Seven Deadly Sins and their "super" variants are major mini-bosses. Krampus, Uriel, Gabriel, and the Fallen Angels are also mini-bosses and does not relate to the Seven Deadly Sins.
