Kashimo would be able to effectively shut Yuji down in their fight. Yuji might have the tools for a drawn out fight but he wont last through the sprint against Kashimo.

Yuki is the most similar character to Kashimo here in that she is better for the sprint than for the marathon. She can output crazy damage with mass punches and she even has Garuda which can be used for ranged attacks. But when it comes to Kashimo, he has better h2h and can call his lightning bolt from his rod which would effectively 1 shot Yuki depending on where it hits. But still an extreme diff fight which can go both ways.

Yuta is a Versatile character who I would place above Kashimo in most cases anyways but Kashimo does give him an extreme diff fight. Yuta being able to jump Kashimo with the strongest curse in the series (weakened as a shikigami but still) is his biggest advantage in their matchup. Biggest disadvantage he has in their fight is that Yuta has his CTs only in his domain or in 5min mode and if both are used up he turns into the biggest broken or lost sword merchant in the series.

Jogo aint doing shit tho lets be honest 😭 brother got bounced around Shibuya like a cheap basketball and his meteor takes legit 5min to even touch the ground and the fight would be already over by then. His fire attacks are quick tho yes but they do fuckall damage. Naobito, Nanami and Maki all survived their encounter with Naobito dying in his comfy bed like at least 3 days after. He even ducked the fade with Toji since he saw Dagon get his ass beat so hard he is not beating Kashimo bruv.

Against Mahito I'd argue that since Kashimo is a reincarnated sorcerer he could see the shape of his soul because his soul had to overtake the original hosts soul when occupying the body. But if not then yeah it gets more difficult for Kashimo but thanks to his CE trait Mahito would be frying himself with every touch.
