why are ba chartags formatted as "[first name]_(blue archive)" instead of by their full names? this is probably something thats been brought up a ton of times before but it kinda confuses me. only explanation i can think of is that some characters (like Arona) only have a first name but most characters in other copyrights with full names have them as their tag even if most of the other characters in them don't (think Blue Oak vs Red (Pokemon) for example). what's the deal
