It’s PANDRA as seen in the official post and images above. Both PANDRA and PANDORA can be written as パンドラ in Katakana.
Mao still wrote it as PANDRA in this post after talking about the missing O earlier.

It’s understandable that some people may be skeptical about the band’s English skills that this could be a misspelling given them releasing a song named “a holy terrors” in the past lol.
Yes, it says all new tracks including the new single.
パンドラ pa n do ra can only be read as… pandora. It wouldnt surprise me if he means pandoras box or something edgy like that.
Well I am hyped!
What about ドラ in Dragon ball?
I wanna be mad at this but I laughed cuz it’s low-key true 
(chill on my boys).
This is great news. SADIE has been on fire since they returned. Excited to hear fresh music 
Dragon Ball written in katakana isドラゴンボール (doragon bōru)…?
But how do the pandas fit into the concept?
So Dra in Dragon Ball (ドラゴンボール) is written in katakana as ドラ just like DRA in PANDRA (パンドラ).
