But we forget, Kubo still has several ways to stop the fight before it comes to a conclusion. For example, more people can show up to fight. And maybe an even better example: The "shadows" that stopped Yhwach from killing Ichigo make another appearance (you had all forgotten about them, hadn't you?). It was implied that they wouldn't effect him in Soul Society during the second invasion because he had swapped it with the Quincy's base, but that isn't the case now
