Hajime Kashimo (鹿紫雲かしも一はじめ Kashimo Hajime?),[2] known as The God of Lightning (雷らい神じん Raijin?),[3] is an antagonist-turned-supporting character in the Jujutsu Kaisen series. He is a sorcerer from 400 years ago, currently inhabiting the body of someone Kenjaku prepared as a vessel, and has served as a player in Kenjaku's Culling Game, seeking to find and consequently battle Sukuna.

400 years ago, Hajime was an elderly man with cyan-colored eyes with short zig-zag lines underneath them. He had thick eyebrows and long cyan-colored hair tied together in a disheveled style. Most of it was kept tied back behind his head with a single band and reached just beyond his neck. He also had some of the hair on top parted and tied into two buns on the right and left sides of his head. He wore a traditional dark-colored haori.

Incarnated into a new body, Hajime has a much younger appearance as a Culling Game player. He retains the lightning-shaped lines connected to the bottom of his eyelids and his disheveled hairstyle is mostly the same but with bangs in the front. Hajime wears simple, white clothing including a large robe with a scrunched collar around the neck area. The sleeves of his robe are slightly rolled up to reveal Hajime's bandage-wrapped forearms. Hajime also wears matching pants and shoes of the same color as well.

Hajime is the perfect example of a jujutsu sorcerer from the past who lives for fighting strong opponents. Towards the end of his life, after presumably spending the majority of it fighting sorcerers, Hajime was ultimately bored and unsatisfied with the battles he fought. He valued life very differently from people of the modern-day and only agreed to Kenjaku's terms in order to fight Sukuna, the most powerful potential opponent.[5]

The incarnated sorcerer quickly became bored with the Culling Game even after slaughtering over forty players. His focus became exclusively on searching out Sukuna[1] which eventually led him to cross paths with Panda and Kinji Hakari. He found Panda to be below average but Hakari provided Hajime with a real challenge, which he found very interesting due to the unique nature of his abilities.[6] Rather than taking the easy route of outlasting Hakari's jackpot, Hajime desired to kill him while he was unkillable for the most satisfying win possible. To Hajime, anything less is how a loser thinks.
