You see the first image and you can understand why it says it's Rio, but then when you see the others, it could just be a random anime character with black hair.
If it's already being generated by AI, I think you can still give it the halo, or at least know that all the Blue Archive characters have one.

Base +6

@ByakuyaT25 of course it won't be identical to the real character due to the change of the art style,and for the halo ,i tried to hide it on purpose cuz i don't like it

Base +4, 42nddegree -6, JPZ4-5 -6

@Gilgameish0 The halo is something extremely important in the Blue Archive characters (and I think Rio's is one of the prettiest) and the fact that even the game's NPCs have some kind of original design today demonstrates their importance.
