Those screenshots were from the Chinese option.
Likewise, the Japanese version has those parts in English mixed with Japanese.
The wording of the announcement is the same as the one for Ragnarok Odyessy, Persona 4, Final Fantasy Asian versions...
It means the Taiwanese release is dual language: English or Chinese text (fully translated), with Japanese audio.
wait so the chinese game has jap audio and voices? thats good. really good. me like. i hope they dont change anything for the chinese version i'd hate to be missing out or experiencing Non-lore content.
