Death's Heads (死の頭 Shi no atama) are flying, disembodied skull heads first appear in Chapter 3.
They are flying white skulls bearing some resemblance to Death. They always move their mouths up and down while floating around.
They are invulnerable, moving diagonally around the room, and dealing damage upon contact. They ultimately die when the room is cleared.
While dying, their expression changed while jaws were falling.
- Death's Heads are immune to Mom's Bra.
- Death's Heads, along with Flesh Death's Head, are the only monsters so far to have a death animation.
- Their Japanese name, "Shi no atama", is translated to "Head of death".
