All of the Danganronpa characters who appear in the video games use the official English romanizations for their tags, rather than literal romanizations. Examples include Fukawa Toko instead of Fukawa Touko, Soda Kazuichi instead of Souda Kazuichi, and Towa Monaca instead of Touwa Monaka. Several anime-only characters also had their tags changed to match the official romanizations (see BUR #16249), but these five were left out for some reason.
