The Bleach: Thousand-Year Blood War arc isn't just the final war arc in Bleach to settle the score between the Soul Reapers and the vengeful Quincy empire. This final arc is also wrapping up various character arcs and subplots to provide closure, such as protagonist Ichigo Kurosaki learning the truth of his Quincy mother and understanding his inner Hollow. Now it's Rukia Kuchiki's turn to get closure in her own character arc.
