Eh, I've gotten used to Diodora's hair color by now. Even if he looks better blonde, it won't change how great it'll be to see him getting demolished.

Sairaorg in the OP is definitely an accidental error, just like Great Red's arm looking a bit like the BG gauntlet. I'd expect both to be fixed in the BD/actual episode (especially based on how Sairaorg looked in the preview for 02).

And they better not miss out on Ise's personal training with Tannin and his buffed state after.
