Aizen Goes Outside! Ichigo Battles Yhwach – Bleach 618
Bleach 618 shows Aizen and Shunsui talk about the outside, to which Aizen is asked if he’d like to breath the air of Soul Society where Yhwach has just destroyed everything. On top of this, Mimihagi prevents the destruction of the world by holding down the Soul King while Ichigo goes head to head against Yhwach, and even cuts his arm off!
