Japanese In an English Game? (Act 8, Chapter 20)

[CleverCreations]

When Jyonna says "Here, warrior." in a text bubble to call you over to the tree in the Sacred Bowers, her voiced dialogue is Japanese (I believe it is anyways). Does she not have the English line for that particular moment? It caught me off-guard and it was kind of strange.

Also in DT, the mobs between first and second bosses say something in Asian language as well, can't determine which one though.
