I will use the tentative translations provided by G.A.S.A on the current Dx2 demon and skill lists. All demons currently in Dx2 have localized names from past games. The majority of skills have localized names from past games, with the exception of a handful of unique skills and passives. The five demon archetypes have no localized names, so this may be a sticking point. I intend to update their translations once the localized version is released.
