Why is he first? That makes little sense in terms of both the show pacing and how Sora is a more prominent character
I wouldn't complain, but it doesn't seem logical
Why do you think Shay will be first? By all accounts Declan is the most likely next character for Arc-V both in terms of game data that I have seen and the plotline of Arc-V. After him the next Arc-V character will probably be Sora, Shay, or Yuto.
