Did they actually change their names?

Seeing that they are now closer than ever,>!possibly being revealed next update!<, I went into a bit of a spiral, but going by the twitter posts and >!the leaked names attached to the IDs!<, it seems that they changed all of their names. From Chinatsu to Summer From Yutane to Aria From Rokudo to Nangong Yu

I think the first two are extremely simple and the third one is fine I guess, but their original names were so cool and iconic after almost two years of waiting, so I’d be pretty disappointed if they actually did change them.

I still hold hope since Rokudo still has suriel on her wing on twitter and the internal ID names aren’t always the name of the character when they release
