Toilet No Hanakosan Vs Kukkyou Taimashi -

Iori kicks the third stall door open before knocking. "...You didn't knock." (Her voice echoes, bloody hands reach out from the toilet.) Iori: "You'll come out whether I knock or not. Now get out here so I can send you to hell." Hanako emerges fully — a floating, vengeful spirit with dripping red eyes. She tries to drag him into the mirror dimension. Iori grabs her wrist. Her eyes widen. Iori: "You're light." (He suplexes her through the bathroom floor into the gymnasium below.) Hanako shrieks, summons hundreds of ghost children. Iori cracks his neck. Iori: "Good. I was worried this would be boring." Is this an actual published crossover? No — there is no official Toilet no Hanakosan vs Kukkyou Taimashi manga, game, or film. It’s likely a fan-made concept, a doujinshi idea, or a prompt for a parody fight scene. However, both characters fit perfectly into a comedy exorcism battle genre.

It seems you're referencing a crossover or versus concept involving (トイレの花子さん, "Hanako of the Toilet") and Kukkyou Taimashi (屈強退魔士, "Sturdy Exorcist" or "Burly Exorcist"). Toilet no Hanakosan vs Kukkyou Taimashi
