He has long, minty-blue hair tied up in two buns and is characterized by lightning-shaped markings under his eyes. He has blue eyes, and his arms are wrapped entirely in bandages except for his hands (not due to injury). Despite his physical training, his build is relatively slim. He stands in the mid-170cm range. Though often overshadowed by his battle-crazed personality, he is surprisingly intelligent and possesses excellent combat sense. He utilizes the electrical properties of his cursed energy to make attacks unfailingly accurate. His mastery of weaponry and martial arts is top-tier, and his proficiency with electricity, combat intuition, and intelligence are incredibly high. He tends to push through any obstacle and is arrogant and somewhat rude due to his strong self-belief. Unexpectedly, he is not very sociable. He uses the Cursed Tool 'Nyoi-bo' to store his lightning-like cursed energy and conduct it into opponents. While his cursed energy isn't literal electricity, it possesses identical properties, meaning even blocked attacks cause damage like an electric shock. Attacking him also results in recoil damage, though he has a resistance to electric shocks that makes the damage less than what the opponent receives. He is male, over 400 years old, and is a reincarnated sorcerer known as the 'God of Thunder.' His techniques include 'Sure-Hit Lightning' (a technique created by applying the properties of his electrical cursed energy to the limit. By separating cursed energy into positive and negative charges, he applies a positive charge upon contact. Once enough positive charge accumulates, he releases the stored negative charge. The attack speed is light-speed, and since the charges are guided by electromagnetic force, the attack is guaranteed to hit) and 'Hollow Basket Wicker' (which requires a hand sign, forcing him to drop his weapon. While the sign only needs to be made once, an opponent using Domain Expansion likely won't let him pick the weapon back up. Fortunately, Kashimo is a powerhouse in martial arts even without a weapon, so the risk is minimal). He likes strong people and dislikes the weak. He enjoys fighting the strong and finds euphoria in it. However, he is cold and bellicose enough to send the weak to the afterlife in a single blow. Since his cursed energy acts like electricity, being surrounded by a conductor like water causes his energy to leak out continuously unless he suppresses it, leading to rapid exhaustion.
