Yondome wa Iya na Shizokusei Majutsushi - Vol. 9 Ch. 37

I'm assuming the "god killer" thing is a mistranslation, sort of. It was probably originally in Kanji and was vague, and she said the explanation in simpler words. But it all comes back to "god killer" in English. Is what I'm guessing.

Unfortunately I couldn't find the raws for this chapter... so I can only guess that the skill name was something like 力ミキラー (Kami Kiraa)... which could mean "Paper Killer", "Hair Killer", or "God Killer"

Or it was some esoteric kanji that you wouldn't know the meaning of unless you looked it up. Kind of like how most people wouldn't know the existence of the word "Apotheosis" unless they encountered it in some form of entertainment. (games, manga/comics, and maybe anime)
