- Blond hair girl who looks like a delicate Bisque doll. Level 89 <Normal> rank monster.
- Outward appearance and speech are elegant, but underneath lies a cruel personality. Moves like an insect, like climbing a tree using sharp nails and toes, joints bent in the wrong direction. In fact, the head is freshly severed, it's not actually attached to the body.
- It has dozens of souls, disposable "Names" that take damage and are discarded, even if its limbs and the body are chopped off, it can be immediately regenerated again. Time required for this to take place is one beat (1/4 of a breath).
- Leonardo cut its head in two with <Assassinate> using <Parallel PLot> faster than it can regenerate, so it died.
- A mass of tentacles wearing a robe. Level 89 <Normal> rank monster.
- Attacks with acid from the tentacles. In addition, it's tentacles are parasitic and can take over monsters. Can keep battle at a back and forth state against multiple people by employing innumerable <Ash Mottled Dog Demon>'s.
- It knows <Lander>'s and <Ancient>'s are dolls(personality software) called NPC's. It cornered Elias by saying "NPC is a doll" using the 'words of death', it was was killed with the help of Elias who came to consciousness again at the words of Kanami.
