As for the character Yuu Ishigami who appears in "Kaguya-sama: Love Is War", many people remember that, in the initial world line, his family name was written with the kanji meaning "stone" + "god" rather than "stone" + "above"
The character named Ishigami Yuu who appears in “Kaguya-sama: Love Is War” is remembered by many as having been Ishigami Yuu written with the kanji for “god” (as in stone-god) in the earlier world line, but in fact it seems he was Ishigami Yuu written with the “above” character (as in stone-above) from the very beginning. Alternatively, as for Yamagami Tetsuya, the perpetrator who assassinated the late former Prime Minister Abe Shinzo, the author has a vivid memory that at first his surname was written with the “god” character (mountain-god). Since his surname contained “god,” the occult and spiritual accounts on Twitter would surely have latched onto it.
