Character A and B are fighting in battle and Character A starts a side battle between character B and Character C in the opponent's territory. Does Character B's ability reactivate?
A side battle begins a new battle phase, but does not begin a new battle, and from what I'm reading in the REG, it seems to imply abilities only activate when a battle begins or a character is brought in from outside the battle. It does not make it clear though, as far as I can tell.
