Tentacle
Tentacle (触手, Shokushu) is the brought onto Naomi via her contact with. At a basic level, it's a way for the Eldritch God to constantly have a hold over her, as a way of surveillance, along with it being a literal curse upon her, one of which is slowly, but surely, killing her. In this case, her remaining lifespan is being measured via her hair color, from its original black, where the pink is her death rate. The speed of the death rate seems to fluctuate throughout the story, causing for Naomi to believing that Cthullu is being fickle with her, and is, in some way, being pleased by certain actions of hers. However, she is unaware of what exactly is pleasing him.

The Curse also seems to act as a reverse form of. She does not need to transform into Cthullu to use the Curse, as it's a constantly active one at a basic level. Through Tentacle, she can produce tentacles by altering the area around her to create them, their form taking whatever it is she altered. Their strength, speed, durability, along with circumstantial abilities, seem to be derived from whatever is being altered. This Curse heavily relies upon her knowledge of the area, as the majority of the tentacles produced seem to be weak in nature. However, she has shown that she could infuse her magic into the tentacles to further augment their capabilities, such as with the infusion of Lunar.
