Direct answer
The collected research confirms a 19-hero launch roster and describes heroes through status effects, Signal Skills, switching roles, and team compatibility. Exact individual rankings vary by source.
The release roster named in the collected research includes Lute, Johnny, Castella, Aria, Dana, Theresia, Ornette, Charlotte, Reina, Astria, Kalien, Kalsion, Cerese, Alex, Eileen, Roxy, Sion, Tarte, and Othell. The exact translated spelling of some names remains 待确认.
Role and team use
Character value depends on the condition a hero creates or converts. A complete party generally needs an opener, a responder, and an extender or stabiliser rather than three isolated damage dealers.
Use tier lists as starting points only. The collected sources disagree on some placements, and no official developer ranking was found.
