The Grasshopper Curse (バッタのい) is a minor antagonist in the Jujutsu Kaisen series. It was a grade 2 cursed spirit born from humanity's hatred of the grasshopper plague. Yuji Itadori encountered it on B2F of Meiji-Jingumae Station while it was guarding the commissioned curtain there.

Appearance
The Grasshopper Curse is named for the obvious type of curse it is. It is a relatively large, bipedal, humanoid curse that strongly resembles a normal grasshopper. The Grasshopper Curse uses two of its six legs to stand on and the other four as arms.

Personality
The Grasshopper Curse is not particularly bright. It is capable of speech and communication to some degree, albeit with some occasional trouble. Despite barely being considered intelligent, the Grasshopper Curse believes itself to be very smart. Upon meeting Yuji nearly everything it talked about revolved about either itself being smart or asking if Yuji if he's smart. When Yuji revealed to it that smart people don't really talk about being smart, it was surprised and covered its mouth to stop talking.

Shibuya Incident Arc
Yuji Itadori encountered the Grasshopper curse munching on a human corpse, when he entered the Shibuya Station at the B2F entrance. The young sorcerer asked the curse about Mahito's whereabouts, to which the Grasshopper responded by answering the question and adding that it's protecting a Curtain here. Yuji took it upon himself to exorcise the curse in order to get rid of the Curtain. The Grasshopper Curse was initially overpowered, so it tried a surprise attack, but it didn't work and Itadori promptly eliminates the curse.

Abilities and Powers
Overall Skill: Evidenced by its ability to communicate, the Grasshopper Curse is at least a semi-grade level cursed spirit. It was tasked with guarding the commissioned curtain and killing non-sorcerers. Despite having natural physical prowess superior to a normal human, Yuji was far superior in physical skill and easily defeated the curse. Mahito mentioned that it must have taken a strong jujutsu sorcerer to defeat him.
