Kamui comes from Naruto, where it is the signature space-time ninjutsu tied to the Mangekyo Sharingan of Obito Uchiha and Kakashi Hatake. The technique warps objects and people into another dimension, which made its name a natural teleport sound for edits long after the series aired. Clips of the shout spread through anime soundboards and short-form edits, where fans pair it with vanish cuts, dodge plays, and dramatic reveals. It remains popular because one word instantly signals an impossible escape or a dimensional shift.
