Ko-Guy

Ko-Guy is a minor antagonist in the Jujutsu Kaisen series. He was a grade 2 cursed spirit born from humanity's hatred of the grasshopper plague. Yuji Itadori encountered him on B2F of Meiji-Jingumae Station while he was guarding the commissioned curtain there.

Appearance
Ko-Guy is named after the obvious type of curse he is. He is a relatively large, bipedal, humanoid curse that strongly resembles a normal grasshopper. Ko-Guy uses two of his six legs to stand on and the other four as arms.

Personality
Ko-Guy is not particularly bright. He is capable of speech and communication to some degree, albeit with some occasional trouble. Despite barely being considered intelligent, Ko-Guy believes himself to be very smart. Upon meeting Yuji nearly everything he talked about revolved about either himself being smart or asking if Yuji if he's smart. When Yuji revealed to him that smart people don't really talk about being smart, he was surprised and covered his mouth to stop talking.

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

Abilities and Powers
Overall Skill: Evidenced by his ability to communicate, Ko-Guy is at least grade 2 level cursed spirit with high combat abilities that surpass some semi-grade 1 curses. He is more intelligent than most curses, but the Grasshopper isn't very smart compared to a typical jujutsu sorcerer. In Shibuya he was given two simple tasks: 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.
